fix: dedupe Aurora Data API incompatibility metadata, normalize solr pin

space in the sqlalchemy-solr version pin for PEP 508 consistency.

-
-            As decided in [SIP-36](https://github.com/apache/superset/issues/9101), all new frontend code should be written in TypeScript. Please convert above files to TypeScript then re-request review.

+## Security and Threat Model
+
+Before evaluating any code path for security issues, read [`SECURITY.md`](SECURITY.md). It is the canonical, authoritative source for Apache Superset's security model and is referenced by both human reporters and automated scanners.
+
+In short, the test for whether a finding is in scope is one question:
+
+> *Does it let a principal perform an action the role and capability matrix in `SECURITY.md` does not entitle them to?*
+
+If yes, it is in scope. If no, it is not.
+
+The three trust boundaries are:
+
+1. **The Admin role** is a fully trusted operational principal. Anything an Admin can do through documented configuration, API, or UI is an intended capability, not a vulnerability.
+2. **The operator** owns deployment-time decisions (secrets, network exposure, feature-flag selection, connector and codec choices, notification destinations, third-party plugins). Misconfiguration at this layer is a deployment defect, not a Superset vulnerability.
+3. **The codebase** is responsible for enforcing the role and capability matrix wherever it exposes functionality to a principal: API routes, command and DAO layers, UI handlers, background jobs, and any other entry point. A missing or incorrect enforcement check is in scope no matter where it lives.
+
+The security model assumes that operator-controlled infrastructure, including the metadata database, cache backends, message brokers, secret stores, and deployment environment, remains within the operator's trust boundary. Vulnerabilities must demonstrate a security boundary violation by an attacker who does not already control those systems.
+
+Route-level authorization in this codebase uses one of three Flask-AppBuilder decorators depending on the route type:
+
+- `@protect()` for REST API routes (`ModelRestApi` / `BaseApi`)
+- `@has_access_api` for legacy view routes
+- `@has_access` for legacy HTML view routes
+
+Object-level authorization via `security_manager.raise_for_access(...)` applies to data-bearing resources: dashboards, charts, datasets and datasources, queries, database and table access, and query contexts. Other resources (annotations, tags, CSS templates, reports, RLS rules, and similar) rely on the route-level decorator plus DAO `base_filters` for ownership scoping; the absence of `raise_for_access` on these resources is by design, not a finding. Code that omits the per-object gate on a route that returns or mutates a specific data-bearing object is in scope; code that follows the correct pattern for its resource class can still contain injection, SSRF, XSS, or other classes of finding unrelated to authorization, which are evaluated separately.
+
+The full role and capability matrix, in-scope and out-of-scope class lists, and CVE aggregation rules are in [`SECURITY.md`](SECURITY.md). Defer to that document for any specifics.
+
+**Requirements for findings filed by automated tooling**
+
+Automated scanners (LLM-based code scanners, static analyzers, dependency tools) that file findings against this codebase must, in each finding, name:
+
+1. The specific role and capability matrix row in [`SECURITY.md`](SECURITY.md) the finding believes is violated.
+2. The principal the finding assumes the attacker holds (Public, Gamma, sql_lab, Alpha, Admin, Embedded guest token, or a custom role with explicit capability grants).
+
+Findings that cannot identify both should be filed as questions, not vulnerabilities. This requirement exists to ensure every reported issue is testable against the published security model and to keep speculative or pattern-match-only reports out of the triage queue.

+# Security Policy
+
+This is a project of the [Apache Software Foundation](https://apache.org) and follows the
+ASF [vulnerability handling process](https://apache.org/security/#vulnerability-handling).
+
+## Reporting Vulnerabilities
+
+**⚠️ Please do not file GitHub issues for security vulnerabilities as they are public! ⚠️**
+
+
+Apache Software Foundation takes a rigorous standpoint in resolving the security issues
+in its software projects. Apache Superset is highly sensitive and forthcoming to issues
+pertaining to its features and functionality.
+If you have any concern or believe you have found a vulnerability in Apache Superset,
+please get in touch with the Apache Superset Security Team privately at
+e-mail address [security@superset.apache.org](mailto:security@superset.apache.org).
+
+More details can be found on the ASF website at
+[ASF vulnerability reporting process](https://apache.org/security/#reporting-a-vulnerability)
+
+**Submission Standards & AI Policy**
+
+To ensure engineering focus remains on verified risks and to manage high reporting volumes, all reports must meet the following criteria:
+- Plain Text Format: In accordance with Apache guidelines, please provide all details in plain text within the email body. Avoid sending PDFs, Word documents, or password-protected archives.
+- Mandatory AI Disclosure: If you utilized Large Language Models (LLMs) or AI tools to identify a flaw or assist in writing a report, you must disclose this in your submission so our triage team can contextualize the findings.
+- Human-Verified PoC: All submissions must include a manual, step-by-step Proof of Concept (PoC) performed on a supported release. Raw AI outputs, hypothetical chat transcripts, or unverified scanner logs will be closed as Invalid.
+
+We kindly ask you to include the following information in your report to assist our developers in triaging and remediating issues efficiently:
+- Version/Commit: The specific version of Apache Superset or the Git commit hash you are using.
+- Configuration: A sanitized copy of your `superset_config.py` file or any config overrides.
+- Environment: Your deployment method (e.g., Docker Compose, Helm, or source) and relevant OS/Browser details.
+- Impacted Component: Identification of the affected area (e.g., Python backend, React frontend, or a specific database connector).
+- Expected vs. Actual Behavior: A clear description of the intended system behavior versus the observed vulnerability.
+- Detailed Reproduction Steps: Clear, manual steps to reproduce the vulnerability.
+
+## Security Model
+
+This section defines what Apache Superset considers a security issue and what it does not. It is the canonical reference for reporters, the Apache Superset Security Team, and any automated tool (LLM-based scanner, static analyzer, dependency tool) that needs to constrain its hypotheses to behaviors that genuinely violate the project's security policy.
+
+The model is intentionally written in terms of principals, trust boundaries, and capability surface rather than in terms of specific files, functions, or libraries. New code paths inherit the model automatically.
+
+### Trust Boundaries
+
+Apache Superset's threat model assumes three trust boundaries.
+
+1. *The Admin role* is a fully trusted operational principal. Anything an Admin can do through the documented user interface, REST API, or configuration system is an intended capability, not a vulnerability, even if individually powerful or destructive. The Admin role is, by policy, equivalent to operating-system-level trust over the Apache Superset application. This is unavoidable rather than aspirational: an Admin can, for example, register new database connections of arbitrary type, execute arbitrary SQL through SQL Lab, render Jinja templates that resolve to SQL or rendered HTML, and override application configuration. Granting Admin is functionally equivalent to granting shell access on the host, which is the reasoning behind treating it as a trust boundary in the sense of MITRE CNA Operational Rules 4.1.
+
+2. *The operator* is whoever deploys, configures, and runs Apache Superset. Behaviors that depend on deployment-time decisions are the operator's responsibility, not Apache Superset's. This includes the values of secrets, the network reachability of the application and its data sources, the choice of database connectors and cache backends, the selection of feature flags, the destinations of notifications, and the trust placed in third-party plugins. Defaults that fail closed are the responsibility of the Apache Superset codebase. Defaults that fail open must be accompanied by a documented hardening requirement; applying that hardening is the operator's responsibility, while shipping an undocumented or unflagged fail-open default is a codebase issue.
+
+3. *The Apache Superset codebase* is responsible for enforcing the role and capability matrix below across its product surface. A failure to enforce, anywhere in that surface, is in scope. The codebase's commitments are limited to the role and capability matrix and to controls Apache Superset's own documentation (this file and the linked Security documentation) explicitly positions as security boundaries; configurable hardening that operators can layer on top is treated separately under *Vulnerability Scope* below.
+
+### Roles and Capabilities
+
+Apache Superset ships with the following first-class principals. Detailed permission definitions live in the [Security documentation](https://superset.apache.org/docs/security).
+
+| Principal | Read data | Write objects | Execute SQL | Manage databases | Manage users, roles, RLS |
+|---|---|---|---|---|---|
+| Public (anonymous) | none by default | no | no | no | no |
+| Gamma | only granted datasets | own charts and dashboards on granted datasets | no by default (requires the `sql_lab` role) | no | no |
+| Alpha | all data sources | own charts, dashboards, and datasets | no by default (requires the `sql_lab` role) | data upload to existing databases only | no |
+| Admin | all | all | yes | yes | yes |
+| Embedded guest token | data sources reachable through the embedded dashboards the token authorizes | no | no | no | no |
+
+The `sql_lab` role is *additive*: it grants the SQL Lab permission set on top of the base role above, and is the only path by which Gamma or Alpha gain SQL execution capability. Database access is still scoped per the base role's grants. Admin includes SQL Lab access by default.
+
+Deployments may grant or revoke individual view-menu permissions, which shifts the boundary for that deployment but does not redefine the model. Any custom role created by an operator inherits the same principle: its capabilities are whatever the operator has explicitly granted it. The Public principal follows the same rule: operators may grant the Public role read access to specific datasets or dashboards (typically for anonymous reporting use cases), which shifts the boundary for that deployment without redefining the model.
+
+### Vulnerability Scope
+
+The test for whether a finding is in scope is a single question:
+
+> *Does this finding let a principal perform an action the role and capability matrix above does not entitle them to?*
+
+If yes, it is in scope. If no, it is out of scope. The lists below apply that test to the classes Apache Superset most commonly receives reports about; they are illustrative, not exhaustive.
+
+*In Scope*
+
+- A user, embedded guest, or anonymous visitor reads, modifies, or deletes data outside their granted set. Includes object-level access bypass on charts, dashboards, datasets, saved queries, tags, annotations, and similar per-object endpoints, and row-level-security rule bypass.
+- A user supplies input that the codebase should sanitize or parameterize but does not, causing arbitrary SQL, template code, or scripts to execute. Includes injection through Jinja templates, SQL-construction paths, and any field the codebase passes to a query engine or template engine.
+- A user bypasses authentication, fixates or reuses another user's session, or reaches an authenticated endpoint without logging in.
+- An embedded guest token authorizes actions outside the dashboard it was issued for, or can be forged, replayed, or escalated to a higher principal.
+- Apache Superset, acting on behalf of an unprivileged user, fetches an outbound URL the user controls in a feature where Apache Superset itself, not the operator, controls the outbound destination set (server-side request forgery).
+- An Apache Superset default fails open without an accompanying documented hardening requirement. The codebase is responsible for shipping fail-closed defaults or for documenting the hardening required when a default fails open; failures of that responsibility are in scope (see *Trust Boundaries*).
+- A user bypasses a control Apache Superset documents specifically as a security boundary. This includes row-level security, the access checks tied to the role and capability matrix above, and any feature whose documentation positions it as security-relevant. The codebase commits to enforcing those controls; bypasses are in scope regardless of which principal triggers them.
+- A user causes a script to execute in another user's browser through a field the codebase renders to that other user (cross-site scripting), or causes cross-origin leakage of authenticated session state or data.
+- A user reaches a route, page, or API endpoint that requires a role they do not have.
+
+*Out of Scope*
+
+- Any action an Admin role can perform through documented configuration, API, or UI. The Admin role is a trusted operational principal by policy. Per MITRE CNA Operational Rules 4.1, a qualifying vulnerability must violate a security policy; behavior within a documented trust boundary does not.
+- Deployment or operator decisions: the values of secrets and tokens, whether internal networks are reachable from the server, which database connectors or cache backends are enabled, which feature flags are set, where notifications are delivered, and which third-party plugins are loaded.
+- Compromise, modification, or malicious control of trusted backend infrastructure. Apache Superset assumes the integrity of its metastore, cache backends (for example Redis or Memcached), message brokers, secret stores, and other operator-managed infrastructure. Findings that require an attacker to read from, write to, or otherwise tamper with these systems, including injecting malicious state, serialized objects, cache entries, task metadata, configuration, or database records, are post-compromise scenarios and do not constitute vulnerabilities in Apache Superset itself. A finding remains in scope only if an unprivileged user can cause such modification through a vulnerability in Apache Superset.
+- The continued presence of expired key-value or metastore-cache entries that have not yet been deleted from the metadata database. Such entries are excluded from reads once expired, are purged opportunistically on write, and are removed in bulk by the scheduled `prune_key_value` maintenance task; their lingering until purged is an eventual-cleanup property, not a security boundary, and does not constitute a vulnerability.
+- How a downstream application (spreadsheet program, email client, browser handling user-downloaded files) interprets output Apache Superset produced for it.
+- Findings without a reproducible proof of concept against a supported release. The burden of demonstrating exploitability rests with the reporter; findings closed for lack of a proof of concept may be refiled if one is later produced.
+- Brute force, rate limiting, denial of service, or resource exhaustion that does not bypass a documented control.
+- Missing security headers, banner or version disclosure, user or object enumeration through error messages or timing, and similar low-impact information disclosure that does not enable a further concrete exploit.
+- Bypasses of configurable defense-in-depth hardening that Apache Superset does not document as a security boundary. Apache Superset is not a SQL or database firewall: operator-deployable filters such as SQL function or table denylists, URI restrictions on already-authorized database connectors, and similar belt-and-braces controls are provided to let operators layer hardening on top of the role and capability matrix, not as firewall-grade guarantees the codebase commits to. Findings against such hardening are improvements, not vulnerabilities, unless the documentation positions the specific control as security-relevant.
+- Hardening suggestions that improve defense in depth but do not violate the security model.
+
+Findings in third-party dependencies fall into two cases. A finding in a transitive dependency, or in an operator-selected dependency that Apache Superset does not ship, is out of scope and should be reported to the dependency's maintainers. A finding caused by Apache Superset pinning a known-vulnerable version of a direct dependency it ships, or using a dependency in a way that creates a vulnerability the dependency itself does not have, remains in scope. Dependency findings in the official Apache Superset Docker image that fall into the first case can be remediated by extending the image at release time.
+
+When uncertain whether a finding falls in scope, please file it through the reporting process above. The triage team will classify it and explain the reasoning if it is closed as out of scope.
+
+**Outcome of Reports**
+
+Reports that are deemed out of scope for a CVE but represent valid security best practices or hardening opportunities are typically converted into public GitHub issues, where the community can contribute fixes alongside the maintainers. The triage decision and reasoning are communicated back to the reporter in either case.
+
+**Vulnerability Aggregation & CVE Attribution**
+
+In accordance with MITRE CNA Operational Rules (4.1.10, 4.1.11, and 4.2.13), Apache Superset issues CVEs based on the underlying architectural root cause rather than the number of affected endpoints or exploit payloads.
+- Aggregation: If multiple exploit vectors stem from the same programmatic failure or shared vulnerable code, they must be aggregated into a single, comprehensive report.
+- Independent Fixes: Separate CVEs will only be assigned if the vulnerabilities reside in decoupled architectural modules and can be fixed independently of one another.
+Reports that fail to aggregate related findings will be merged during triage to ensure an accurate and defensible CVE record.
+
+**Your responsible disclosure and collaboration are invaluable.**

+### Dashboard "Export Data to Excel" requires a Celery worker and S3 bucket
+
+A new dashboard action exports every chart's data to a single multi-sheet
+`.xlsx` asynchronously. It is disabled by default and turns on only when
+`EXCEL_EXPORT_S3_BUCKET` is set (the endpoint returns `501` otherwise). It also
+requires a running Celery worker and a configured SMTP transport, since the task
+emails the requesting user a pre-signed download link. New config keys:
+`EXCEL_EXPORT_S3_BUCKET`, `EXCEL_EXPORT_S3_KEY_PREFIX`,
+`EXCEL_EXPORT_LINK_TTL_SECONDS`, `EXCEL_EXPORT_S3_CLIENT_KWARGS`, and
+`EXCEL_EXPORT_TABLE_VIZ_TYPES`.
+
+The feature depends on `boto3`, which is **not** installed by default; install it
+with `pip install apache-superset[excel-export]`.
+
+A second mode, **Export Images to Excel**, embeds non-table charts as rendered
+images (which viz types stay tabular is controlled by
+`EXCEL_EXPORT_TABLE_VIZ_TYPES`). It renders through the headless webdriver, so the
+menu option only appears when the webdriver screenshot feature flags
+(`ENABLE_DASHBOARD_SCREENSHOT_ENDPOINTS`,
+`ENABLE_DASHBOARD_DOWNLOAD_WEBDRIVER_SCREENSHOT`) are enabled.
+
+Deployments that override `CELERY_CONFIG` must add
+`"superset.tasks.export_dashboard_excel"` to their `imports` tuple, or the task
+will not register and exports will silently never run.
+
+### SQL_QUERY_MUTATOR now honors MUTATE_AFTER_SPLIT in SQL Lab
+
+SQL Lab now applies `SQL_QUERY_MUTATOR` according to `MUTATE_AFTER_SPLIT`, matching the documented semantics and the chart/query path. This only affects deployments that define `SQL_QUERY_MUTATOR` in `superset_config.py`:
+
+- With `MUTATE_AFTER_SPLIT = True`, the mutator previously never ran in SQL Lab; it now runs on each individual statement (including on engines like BigQuery and Kusto that execute multiple statements as one block, where each statement is mutated before the statements are joined).
+- With `MUTATE_AFTER_SPLIT = False` (the default), multi-statement SQL Lab queries previously applied the mutator to each statement separately; the mutator now runs once on the whole un-split query, as documented. Single-statement queries are unaffected.
+- With `MUTATE_AFTER_SPLIT = False` on engines that execute statements individually, the mutator's output is re-parsed to split it into statements. A mutator that emits SQL Superset's parser cannot parse will now fail with a clear parse error before execution, and one that strips a query down to nothing raises an invalid-SQL error instead of executing an empty query.
+
+### Python 3.10 support removed
+
+Python 3.10 is no longer supported. Superset now requires **Python 3.11 or higher**.
+Update your environment (virtualenv, Docker base image, CI configuration, etc.) to
+Python 3.11+ before upgrading. The `apache/superset-cache:3.10-slim-trixie` and
+`py310` Docker image variants are no longer published.
+
+### `from_dttm` and `to_dttm` Jinja template variables removed
+
+The `{{ from_dttm }}` and `{{ to_dttm }}` Jinja template variables, deprecated since
+v5.0, have been removed from the Jinja context and are no longer available in virtual
+dataset SQL or custom SQL expressions.
+
+Replace usages with the `get_time_filter()` function. For example:
+
+```sql
+-- Before
+SELECT * FROM tbl
+WHERE dttm_col > '{{ from_dttm }}' AND dttm_col < '{{ to_dttm }}'
+
+-- After
+{% set tf = get_time_filter("dttm_col") %}
+SELECT * FROM tbl
+WHERE dttm_col > {{ tf.from_expr }} AND dttm_col <= {{ tf.to_expr }}
+```
+
+Note that `from_expr` and `to_expr` are already fully-formatted SQL expressions (e.g.
+`TO_TIMESTAMP('2024-01-01', ...)`) — do not wrap them in single quotes.
+
+### Removed deck.gl JavaScript tooltip/data-mutator controls and ENABLE_JAVASCRIPT_CONTROLS
+
+The `ENABLE_JAVASCRIPT_CONTROLS` feature flag and the deck.gl chart controls it gated
+(`js_tooltip`, `js_onclick_href`, `js_data_mutator`, and the GeoJSON layer's label/icon
+JavaScript-mode generators) have been removed. These controls let users write arbitrary
+JavaScript, sandboxed via Node's `vm` module, to customize deck.gl tooltips, click
+behavior, and data transforms; the flag defaulted off and the feature saw negligible use.
+
+The deck.gl "Extra data for JS" control (`js_columns`) has also been removed. It only
+ever existed to feed extra columns into the JavaScript controls above; deck.gl's
+built-in field-based tooltips and cross-filtering already pull in any columns they need
+via `tooltip_contents`/`cross_filter_column`, so this control had no remaining purpose.
+Any chart layer whose "Advanced" control panel section only contained this control no
+longer has an "Advanced" section.
+
+Any saved charts with these fields set will simply ignore them going forward and fall back
+to deck.gl's built-in field-based tooltips (`tooltip_contents`/`tooltip_template`) and
+native click/cross-filter behavior. No migration is required; the fields are dropped
+silently on next save.
+
+### Owners, dashboard roles, and RLS roles replaced by Subjects
+
+Superset now uses subject-based access assignments for dashboards, charts, datasets,
+alerts/reports, and Row Level Security. A Subject can represent a user, role, or group.
+
+This is a breaking API and metadata change:
+
+- `owners` is replaced by `editors` for dashboards, charts, datasets, and alerts/reports.
+- Dashboard `roles` and the `DASHBOARD_RBAC` feature flag are replaced by dashboard/chart
+  `viewers`, enabled with `ENABLE_VIEWERS`.
+- RLS `roles` is replaced by `subjects`.
+- The legacy `dashboard_user`, `slice_user`, `sqlatable_user`, `report_schedule_user`,
+  `dashboard_roles`, and `rls_filter_roles` tables are migrated into subject junction tables
+  and dropped on upgrade.
+
+For deployments that previously used `DASHBOARD_RBAC` and later disabled it: remove stale rows
+from the legacy `dashboard_roles` table before upgrading, otherwise those role assignments will
+become active dashboard Viewers after migration.
+
+API clients and automation should send and read `editors`, `viewers`, and `subjects` instead
+of the legacy fields.
+
+Subject pickers support users, groups, and roles, but only users and groups are selectable by
+default. Roles remain supported as Subject types for backwards compatibility with RLS role
+assignments and the previous `DASHBOARD_RBAC` model, but they are not recommended for new
+resource-specific assignments. Prefer groups for membership-based access and keep roles focused
+on capability grants. Existing Role subject assignments remain effective after migration even when
+Roles are hidden from the default dropdown values; configure the relevant `SUBJECTS_RELATED_TYPES_*`
+setting to make Roles selectable when editing subject lists. See the [Security documentation](docs/admin_docs/security/security.mdx#subjects)
+for the full Subject model and picker configuration guidance.
+
+To make roles selectable everywhere:
+
+```python
+from superset.subjects.types import SubjectType
+
+SUBJECTS_RELATED_TYPES = [
+    SubjectType.USER,
+    SubjectType.GROUP,
+    SubjectType.ROLE,
+]
+```
+
+To make roles selectable for RLS while other pickers keep the user and group default, use the
+RLS-specific override:
+
+```python
+from superset.subjects.types import SubjectType
+
+SUBJECTS_RELATED_TYPES_RLS = [
+    SubjectType.USER,
+    SubjectType.GROUP,
+    SubjectType.ROLE,
+]
+```
+
+Entity-specific `SUBJECTS_RELATED_TYPES_*` settings replace `SUBJECTS_RELATED_TYPES` for that
+picker.
+
+Deployments using `EXTRA_OWNERS_RESOLVER` must migrate to `EXTRA_EDITORS_RESOLVER`. The new
+resolver should return editor Subjects, subject IDs, or dicts with an `id` key instead of FAB
+User objects. API responses expose these dynamic assignments as `extra_editors` instead of
+`extra_owners`.
+
+`DASHBOARD_RBAC` has been removed. To preserve the previous Dashboard RBAC behavior, enable both
+subject viewers and viewer datasource bypass:
+
+```python
+FEATURE_FLAGS = {
+    "ENABLE_VIEWERS": True,
+}
+VIEWER_PROMISCUOUS_MODE = True
+```
+
+Enabling only `ENABLE_VIEWERS` allows assigning dashboard/chart viewer subjects, but viewers still
+need normal datasource permissions unless `VIEWER_PROMISCUOUS_MODE` is also enabled.
+
+For backwards compatibility, enabling `ENABLE_VIEWERS` does not change access for dashboards or
+charts that have no assigned viewers. Those resources continue to use the implicit dataset-access
+model: users who can access the underlying dataset can still see published dashboards that use that
+dataset and charts backed by that dataset.
+Assigning one or more viewers opts that resource into explicit viewer access for non-editors. To
+return a resource to the implicit dataset-access model, remove all viewers from it. Explicit Viewers
+are the intended model going forward; deprecating and removing implicit viewership can be considered
+in a later major version.
+
+- [41044](https://github.com/apache/superset/issues/41044): Removes the deprecated `AVOID_COLORS_COLLISION` feature flag (it defaulted to `True`). Color-collision avoidance is now permanently enabled; any config override setting it to `False` is ignored.
+
+- [41813](https://github.com/apache/superset/pull/41813): `redis` (the Python client, `redis-py`) is bumped from 5.3.1 to 8.0.1. redis-py 8 changes several connection defaults; Superset's own Redis-backed features (`GLOBAL_ASYNC_QUERIES_CACHE_BACKEND`, `DISTRIBUTED_COORDINATION_CONFIG`, and the MCP Redis store) explicitly pin the pre-upgrade behavior so this bump is a no-op for them: the wire protocol stays RESP2 (not the new RESP3 default, which requires Redis/Sentinel 6+ to speak `HELLO`) and there is still no socket timeout by default (redis-py 8 defaults to 5s, which could otherwise newly time out large cached payloads or slow networks). The no-timeout default can now be overridden via two new config keys, `CACHE_REDIS_SOCKET_TIMEOUT` / `CACHE_REDIS_SOCKET_CONNECT_TIMEOUT`, on any `CacheConfig` dict using `CACHE_TYPE: RedisCache` or `RedisSentinelCache`. Separately, redis-py 6+ changed the default for `ssl_check_hostname` from `False` to `True` for SSL connections using `ssl_cert_reqs="required"` (the default) — this is a security improvement, so it has **not** been reverted; deployments with `CACHE_REDIS_SSL=True` whose certificates lack a hostname matching the connection address should set `CACHE_REDIS_SSL_CERT_REQS="none"` (disables cert verification entirely, matching hostname-check bypass) or replace the certificate. General-purpose cache/results backends configured via `CACHE_CONFIG` / `DATA_CACHE_CONFIG` / `RESULTS_BACKEND` with `CACHE_TYPE: RedisCache` go through `flask-caching`'s own Redis backend (outside Superset's code) and are subject to the same new defaults; pass `socket_timeout` / `protocol` via `CACHE_OPTIONS` there if needed. Celery broker and result-backend connections (built by `kombu`, also outside Superset's code) keep their no-socket-timeout behavior (`kombu` passes `socket_timeout=None` explicitly) but do **not** pin the wire protocol, so they follow redis-py's RESP3 default — which requires a Redis server new enough to speak `HELLO` (Redis 6+). Deployments using a pre-6.0 Redis server (EOL) as a Celery broker should upgrade the server before taking this bump.
+
+- [39925](https://github.com/apache/superset/pull/39925): URL prefixing for `SUPERSET_APP_ROOT` subdirectory deployments is now handled automatically by helpers in `src/utils/navigationUtils` (`openInNewTab`, `redirect`, `getShareableUrl`, `<AppLink>`). Direct imports of `ensureAppRoot` / `makeUrl` from `src/utils/pathUtils` are forbidden outside `navigationUtils.ts` (enforced by a static-invariant test); contributors writing new code should use the focused helpers instead. No runtime behaviour change for existing callers — all 19 prior call sites have been migrated and four pre-existing double-prefix and missing-prefix bugs are fixed as part of the migration.
+
+- [39925](https://github.com/apache/superset/pull/39925): `SupersetClient.getUrl()` now strips a single leading application-root segment from the supplied `endpoint` before building the request URL, so a caller that accidentally pre-prefixes its endpoint (for example by wrapping it with `ensureAppRoot` before passing it to the client) no longer produces a doubled `/superset/superset/...` URL under subdirectory deployment. The strip is **single-pass** — a genuine `/superset/superset/<slug>` route is preserved, not collapsed — and **silent** (no console warning); the static-invariant test remains the primary signal for pre-prefixing at the call site, and this runtime strip is a safety net beneath it. Code that intentionally targeted a literal `/<app_root>/<app_root>/...` endpoint through `getUrl` (a configuration that has no legitimate use under the prefixing model) would have its first redundant segment removed.
+
+- **Breaking — `Superset` view class route prefix removed.** The `Superset` view in `superset/views/core.py` now declares `route_base = ""`, overriding Flask-AppBuilder's auto-derived `/superset` prefix. Routes that previously lived at `/superset/welcome/`, `/superset/dashboard/<id>/`, `/superset/dashboard/p/<key>/`, `/superset/explore/`, etc. now respond at `/welcome/`, `/dashboard/<id>/`, `/dashboard/p/<key>/`, `/explore/`, etc. Under subdirectory deployment (`SUPERSET_APP_ROOT=/superset`) the URLs are unchanged from end-user perspective — `AppRootMiddleware` re-applies the prefix via `SCRIPT_NAME`. Under root deployments, any external integration or bookmark that hard-codes `/superset/<endpoint>/` paths must be updated to drop the prefix. This fixes the doubled `/superset/superset/...` URLs that `url_for` emitted for these endpoints under subdirectory deployment and the related 404s on the routes themselves.
+
+- **Breaking — Three sibling view classes route prefix removed.** Following the same rationale as the `Superset` class above, `ExplorePermalinkView` (`superset/views/explore.py`), `TagModelView`, and `TaggedObjectsModelView` (`superset/views/tags.py`, `superset/views/all_entities.py`) now mount at the application root rather than a hard-coded `/superset/...`. The user-visible URLs `/superset/explore/p/<key>/`, `/superset/tags/`, and `/superset/all_entities/` are unchanged under subdirectory deployment; under root deployments these views now serve `/explore/p/<key>/`, `/tags/`, and `/all_entities/`, so any external integration or bookmark must drop the `/superset/` prefix. `Dashboard.url` and `Dashboard.get_url` likewise return `/dashboard/<id>/` instead of the prior `/superset/dashboard/<id>/` literal so downstream consumers (DashboardList row hrefs, MCP service `dashboard_url`) emit a single, deployment-correct prefix.
+
+- **Legacy `/superset/*` path support.** A new outermost WSGI middleware `LegacyPrefixRedirectMiddleware` (`superset/middleware/legacy_prefix_redirect.py`) 308-redirects every enumerated legacy `/superset/<canonical>` path to its post-`route_base=""` canonical location (e.g. `/superset/welcome/` → `/welcome/` under root; → `/superset/welcome/` under `SUPERSET_APP_ROOT=/superset`, because the canonical resolves through `AppRootMiddleware`). Bookmarks, email links, and external integrations survive the route-base collapse for one release cycle. POST against a GET-only canonical returns 410 Gone instead of 308 (308 would 405 on retry). The shim is removed at EOL `5.0.0`, matching the `@deprecated(eol_version="5.0.0")` gate on `Superset.explore` and `Superset.explore_json`.
+
+- **PWA web app manifest served dynamically.** The PWA manifest is now served at `/pwa-manifest.json` (under `APPLICATION_ROOT`) by a new `PwaManifestView` (`superset/views/pwa_manifest.py`) instead of the static file at `/static/assets/pwa-manifest.json`. The legacy static source at `superset-frontend/src/pwa-manifest.json` has been removed (along with its `webpack.config.js` `CopyPlugin` rule). The new endpoint resolves `APPLICATION_ROOT` and `STATIC_ASSETS_PREFIX` at request time so PWA install works under subdirectory deployments and split static-prefix / app-root deployments (where `STATIC_ASSETS_PREFIX` points to a CDN host while the Superset backend stays under `APPLICATION_ROOT`). The `<link rel="manifest">` href in `superset/templates/superset/spa.html` was updated correspondingly (using a new `application_root_rstrip` template global). Operators with a forked `spa.html` should switch any manifest `<link>` to `{{ application_root_rstrip }}/pwa-manifest.json`.
+
+- **Hard re-bookmark break — `/superset/sql/<database_id>/`.** SQL Lab moved to its own blueprint at `/sqllab/`. The legacy `/superset/sql/<id>/` shape changed to a query-string form (`/sqllab/?dbid=<id>`); no 1:1 path mapping exists, so `LegacyPrefixRedirectMiddleware` does **not** redirect this route — it passes through and surfaces a 404. Users with bookmarks to `/superset/sql/<id>/` must update them to `/sqllab/?dbid=<id>`.
+
+- **`SqlaTable.sql_url` query-string format.** `SqlaTable.sql_url` now URL-encodes `table_name` and joins it as a query parameter rather than concatenating a second `?`. Previously, with `Database.sql_url` returning `/sqllab/?dbid=<id>`, the concatenation produced `/sqllab/?dbid=<id>?table_name=<raw>` — a malformed second `?` that broke the query parser. External code that parsed the legacy `<base>?table_name=<raw>` shape now sees properly percent-encoded values (e.g. `/` → `%2F`, ` ` → `+` or `%20`); decode with `urllib.parse.parse_qsl`.
+
+- **New config flag `EMBEDDED_DISABLE_PERMALINK_ORIGIN_REWRITE` (default `False`).** Share/permalink URLs now substitute `window.location.origin` for the backend-supplied origin so a proxied or subdirectory-deployed Superset never hands the user an unreachable internal hostname. Operators whose reverse proxy correctly forwards `X-Forwarded-Host` *and* who want permalinks to carry the backend's literal origin can opt out by setting `EMBEDDED_DISABLE_PERMALINK_ORIGIN_REWRITE = True` in `superset_config.py`. Default `False` (rewrite is on); flipping the default would regress the dominant proxied/subdir deployment to an unreachable host.
+
+- [41651](https://github.com/apache/superset/pull/41651): **New do-not-translate standard for translation catalogs.** Strings that must stay identical to the source — icon names (e.g. `bolt`), enum/option values (`step-after`), SQL keywords, API field names (`error_message`), code constants, and example placeholders — are now marked with a `#. do-not-translate` extracted comment. The list lives in the `superset/translations/do-not-translate.txt` registry; `scripts/translations/apply_do_not_translate.py` stamps the marker onto `messages.pot` during `babel_update.sh`, and `pybabel update` propagates it to every `.po`, so the status is consistent across all languages. The AI backfill (`backfill_po.py`) and translators leave these entries untranslated (source fallback). The legacy per-catalog convention (a `# Не переводить` translator comment in the `ru` catalog) is still honored for back-compat but is superseded by this standard; contributors adding new machine-read strings should add the msgid to the registry rather than annotating individual catalogs.
+
+### SQL Lab denies large-object and information_schema access by default
+
+`DISALLOWED_SQL_FUNCTIONS` and `DISALLOWED_SQL_TABLES` now ship with additional default entries, so SQL Lab and chart-data queries that reference them are rejected where they were previously allowed:
+
+- PostgreSQL large-object routines (`lo_from_bytea`, `lo_export`, `lo_import`, `lo_put`, `lo_create`, `lo_creat`, `lowrite`, `lo_get`, `loread`, `lo_unlink`), which read and write bytes on the database server's filesystem.
+- The SQL-standard `information_schema` views (`tables`, `columns`, `routines`, `views`, the privilege/grant views, etc.), which expose table, column, privilege, and view-definition metadata across the whole database.
+
+Deployments that legitimately query these (for example tooling that introspects `information_schema`) can restore the previous behavior by overriding `DISALLOWED_SQL_FUNCTIONS` / `DISALLOWED_SQL_TABLES` in `superset_config.py` to drop the entries they need.
+
+Because the denylist now resolves the effective schema through the query-aware path, PostgreSQL queries that change the `search_path` (e.g. `SET search_path = ...`) are rejected on the SQL Lab execution and cost-estimate paths whenever any `DISALLOWED_SQL_TABLES` entry is configured (the default for PostgreSQL), matching the behavior previously applied only when `RLS_IN_SQLLAB` was enabled.
+
+### SQL parser input length cap (SQL_MAX_PARSE_LENGTH)
+
+The SQL parser now rejects scripts whose UTF-8 byte length exceeds the new
+`SQL_MAX_PARSE_LENGTH` config option (default `1_000_000` bytes) before they are
+handed to sqlglot, which bounds parser memory and CPU usage. A single query
+larger than the cap (for example a very large `IN (...)` list or a big
+virtual-dataset SQL) raises a parse error in SQL Lab and dashboard-generated
+queries. Deployments that legitimately run queries above this size should raise
+the value, and `SQL_MAX_PARSE_LENGTH = None` disables the check entirely.
+
+### Ant Design upgraded from v5 to v6
+
+The frontend now builds against Ant Design 6, and `@superset-ui/core` / `@apache-superset/core` peer-depend on `antd ^6`. Custom plugins, extensions, and themes that interact with Ant Design need review:
+
+- **Internal DOM classes were renamed**, so any custom CSS targeting `.ant-*` internals silently stops matching. Notable renames: `.ant-tabs-content-holder` → `.ant-tabs-body-holder`, `.ant-tabs-content` → `.ant-tabs-body`, `.ant-tabs-tabpane` → `.ant-tabs-content`; `.ant-select-selector` → `.ant-select-content`, `.ant-select-selection-placeholder` → `.ant-select-placeholder`, `.ant-select-arrow` → `.ant-select-suffix`; `.ant-tooltip-inner` → `.ant-tooltip-container`; `.ant-popover-inner` → `.ant-popover-container`; `.ant-steps-item-tail` → `.ant-steps-item-rail`.
+- **Some component props changed or were removed** — e.g. `Select` no longer accepts `dropdownAlign`, `visible`/`onVisibleChange` are `open`/`onOpenChange`, `Dropdown` `overlay` is `menu`, `Steps.Step` children are the `items` prop, and `styles.body` on Tooltip/Popover is `styles.container`.
+- **CSS variables are on by default** in antd 6, and `ThemeConfig.cssVar` no longer accepts a boolean; Superset theme configs using `cssVar: true`/`false` are coerced (`true` → `{}`, `false` → omitted).
+
+Theme tokens are unaffected — antd 6 removed none of the tokens Superset exposes, so existing theme configurations continue to work. See the [Ant Design v6 migration guide](https://ant.design/docs/react/migration-v6) for the complete upstream list.
+
+### Guest-token RLS rules reject unknown fields
+
+The `rls` rules passed to `POST /api/v1/security/guest_token/` are now validated strictly: a rule may only contain `dataset` and `clause`. Previously unknown fields were silently dropped, so a mistyped or legacy scope key (most commonly `datasource` instead of `dataset`) produced a rule with no `dataset`, which is treated as a *global* rule applied to every dataset the embedded resource can reach. Such a request now returns HTTP 400 identifying the offending field instead of issuing a token with an unintended global rule. Integrators that were sending extra fields in RLS rules must remove them; valid dataset-scoped (`{"dataset": 41, "clause": "..."}`) and global (`{"clause": "..."}`) rules are unaffected.
+
+### MCP service requires `MCP_JWT_AUDIENCE` when JWT auth is enabled
+
+When the MCP service has JWT auth enabled (`MCP_AUTH_ENABLED = True`), an audience must be configured via `MCP_JWT_AUDIENCE` so issued tokens are bound to this service. The service now fails to start with a clear configuration error when the audience is unset, instead of starting with audience validation skipped. Deployments that enable MCP JWT auth must set `MCP_JWT_AUDIENCE` to the audience value their identity provider issues for the MCP service. API-key-only MCP deployments (JWT auth disabled) are unaffected.
+
+### Swagger UI is opt-in (off by default)
+
+`FAB_API_SWAGGER_UI` now defaults to `False` and is driven by the `SUPERSET_ENABLE_SWAGGER_UI` environment variable. The interactive Swagger UI / OpenAPI documentation endpoints (e.g. `/swagger/v1`) are therefore no longer exposed by default. To enable them, set `SUPERSET_ENABLE_SWAGGER_UI=true` (the bundled Docker development environment sets this) or override `FAB_API_SWAGGER_UI = True` in `superset_config.py`.
+
+### Build details (git SHA / build number) are admin-only by default
+
+The git SHA and build number surfaced in the "About" section, the bootstrap payload, and the public `/version` endpoint are now only included for admin users by default; the release version string is still shown to everyone. To expose the build details to all users (the previous behavior), set the `SUPERSET_EXPOSE_BUILD_DETAILS` environment variable (or `EXPOSE_BUILD_DETAILS_TO_USERS = True` in `superset_config.py`).
+
+### Helm chart adopts Kubernetes recommended labels (breaking upgrade)
+
+The Helm chart now labels and selects workloads using the [Kubernetes recommended labels](https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/) (`app.kubernetes.io/*`) instead of the legacy `app`/`release` labels. Because a Deployment's `spec.selector.matchLabels` is immutable, `helm upgrade` against an existing release will fail with a `field is immutable` error.
+
+To upgrade, delete the affected workloads (which selector labels changed) before upgrading, then run the upgrade so they are recreated with the new labels:
+
+```bash
+kubectl delete deployment,statefulset -l release=<release-name> -n <namespace>
+helm upgrade <release-name> superset/superset
+```
+
+Alternatively, perform a fresh install. This is a one-time migration; subsequent upgrades are unaffected.
+
+### Time-series tooltips follow the selected time grain
+
+Tooltips on the Time-series and Mixed Time-series ECharts plugins now respect the chart's time grain (and any dashboard-level time-grain override delivered via `extra_form_data`) when the tooltip time format is left on Adaptive formatting (the default). Tooltips read grain-appropriate labels such as `Jan 2021` (month), `2021 Q1` (quarter), `2021` (year), and weekly date ranges, becoming grain-aware like the x-axis, though the two are formatted independently and their labels may not always match exactly. Only a custom, explicitly-set tooltip time format (a d3 format string) is unaffected — that always wins over the grain.
+
+### Pivot table First/Last aggregations follow data order
+
+The pivot table chart's `First` and `Last` aggregations now return the first and last value in data (query result) order, instead of effectively returning the minimum and maximum. Existing pivot tables that use these aggregations for totals/subtotals may show different values after upgrading. For deterministic results, ensure the underlying query has a stable sort order.
+
+### `FetchRetryOptions` callback parameters widened to allow `null`
+
+The `error` and `response` parameters of the `retryDelay` and `retryOn` callbacks in `FetchRetryOptions` (exported from `@superset-ui/core`) are now typed `Error | null` and `Response | null` to match the actual call-site signature provided by `fetch-retry`. Because these parameter types are contravariant, consumers who typed their callbacks with the non-nullable `(attempt: number, error: Error, response: Response) => number` will get a TypeScript compile error. Widen your callback signatures to accept `Error | null` / `Response | null`.
+
+### Pivot Table totals are now computed by the database (per-metric "Aggregation function" control removed)
+
+Pivot Table subtotals and grand totals are now computed by the database at each
+rollup level instead of re-aggregating the already-aggregated cell values on the
+client. This fixes long-standing incorrect totals for non-additive metrics
+(ratios such as `SUM(a)/SUM(b)`, `COUNT_DISTINCT`, `AVG`, percentiles, etc.),
+which previously summed the displayed cell values.
+
+As a result the per-table **"Aggregation function"** control (which let you pick
+how totals were aggregated client-side, e.g. Sum/Average/Count) has been
+removed: totals now always reflect the metric's own definition evaluated at the
+total's granularity. For additive metrics (`SUM`/`COUNT`/`MIN`/`MAX`) the result
+is unchanged. Saved charts that set `aggregateFunction` will ignore it; no
+migration is required. If you previously relied on a plain sum-of-cells total
+for a non-additive metric, that specific behavior is no longer available.
+
+### `thumbnail_url` removed from dashboard list API response
+
+The `thumbnail_url` field has been removed from `GET /api/v1/dashboard/` list responses. External consumers relying on this field must now construct the thumbnail URL client-side using `id` and `changed_on_utc`:
+
+```
+/api/v1/dashboard/{id}/thumbnail/{changed_on_utc}/
+```
+
+The thumbnail endpoint redirects to the current digest URL regardless of whether the supplied digest is exact. If the image is not yet cached, that digest URL may return `202` and trigger async generation. Using `changed_on_utc` as the digest is sufficient for cache-busting purposes.
+
+### Dashboard import can overwrite related charts, datasets, and databases
+
+Re-importing an existing dashboard previously overwrote only the dashboard itself; its related charts, datasets, and databases were never updated (the importer hardcoded `overwrite=False` for them). They can now be overwritten as part of the import.
+
+A new `overwrite_all` form field controls this, and defaults to `false` everywhere, so existing behavior is preserved: passing `overwrite=true` alone still overwrites only the dashboard, exactly as before. To also overwrite the related charts, datasets, and databases on the `/api/v1/dashboard/import/` endpoint, pass `overwrite_all=true` explicitly. The import modal in the UI exposes this as an "also overwrite all assets" checkbox, and the CLI `superset import-dashboards` and the `ImportDashboardsCommand` likewise default `overwrite_all` to `false`.
+
+### Tagging fix for `create_all`-bootstrapped schemas
+
+Only affects deployments whose metadata schema was created with SQLAlchemy's `create_all` (rather than `superset db upgrade`) on a foreign-key-enforcing backend — PostgreSQL, or MySQL with `FOREIGN_KEY_CHECKS=1`. Such schemas carry three invalid foreign keys on `tagged_object.object_id` that break tagging (`TAGGING_SYSTEM = True`) with a `ForeignKeyViolation`. Schemas built via `superset db upgrade` are unaffected.
+
+This release stops the ORM from emitting these constraints, but it cannot drop ones already present in your schema. If affected, drop them manually (names vary by backend, so look them up first):
+
+```sql
+-- PostgreSQL: names are typically tagged_object_object_id_fkey, _fkey1, _fkey2
+ALTER TABLE tagged_object DROP CONSTRAINT <constraint_name>;
+
+-- MySQL: find names via `SHOW CREATE TABLE tagged_object;`
+ALTER TABLE tagged_object DROP FOREIGN KEY <constraint_name>;
+```
+### Entity version-history infrastructure (gated off by default)
+
+Introduces the schema and SQLAlchemy-Continuum wiring that captures version history for charts, dashboards, and datasets, plus read-only `GET /api/v1/{chart,dashboard,dataset}/<uuid>/versions/` endpoints. This ships **inert**: a new config flag `ENABLE_VERSIONING_CAPTURE` defaults to `False`, so no save writes any version rows and the endpoints return empty. It is an operational kill-switch (a release toggle that becomes a permanent ops switch), not a feature flag — set it to `True` to enable capture once validated. The migration is additive; existing entity `PUT` responses gain `old_version_uuid` / `new_version_uuid` body fields and an `ETag` header (both null/absent when capture is off).
+
+A few save- and import-path internals change **unconditionally** (independent of the flag), because the versioned mappers must behave correctly whether or not capture is enabled:
+
+- `DatasetDAO` column/metric updates move from bulk operations to per-row ORM operations, and a metadata refresh now preserves column primary keys via a natural-key (`column_name`) upsert instead of delete-and-reinsert — so charts that reference dataset columns by id keep working across a refresh (previously such references could be invalidated).
+- `ImportExportMixin.reset_ownership` stamps the current user onto `created_by`/`changed_by` when a request context is present (previously left null for the column default to fill).
+- `UpdateDashboardCommand` runs its body under `no_autoflush`.
+
+These are behavior changes that take effect on upgrade regardless of `ENABLE_VERSIONING_CAPTURE`; no operator action is required.
+
+### Cross-entity version activity stream
+
+A read-only companion to the version-history endpoints: each entity type gains a `GET /api/v1/{chart,dashboard,dataset}/<uuid>/activity/` endpoint returning a chronological, access-filtered stream of edits — the entity's own edits plus, for charts and dashboards, transitive edits to related entities during their association windows. Datasets have no related layer in V2, so `include=related` returns an empty stream for a dataset and `include=all` reduces to the dataset's own edits.
+
+| Param | Type | Default | Purpose |
+|---|---|---|---|
+| `since` / `until` | ISO 8601 | — | Bound `issued_at` |
+| `include` | `self` \| `related` \| `all` | `all` | Own edits, related edits, or both |
+| `q` | string | — | Case-insensitive search over the full history, applied before pagination (so `count` reflects matches) |
+| `page` / `page_size` | integer | `0` / `25` | Pagination (`page_size` clamped to 200) |
+
+Authorization reuses the resource's `can_read` permission and per-object `raise_for_access`; related-entity rows are visibility-filtered to what the caller may see. The stream is empty unless version capture is on (`ENABLE_VERSIONING_CAPTURE`).
+
+### Version-history retention (pruning)
+
+Entity version history (the `version_transaction` / `*_version` shadow tables that back version capture) is aged out by a nightly Celery beat task, `version_history.prune_old_versions` (`superset.tasks.version_history_retention`).
+
+| Key | Default | Purpose |
+|---|---|---|
+| `SUPERSET_VERSION_HISTORY_RETENTION_DAYS` | `30` | Version rows whose owning `version_transaction.issued_at` is older than this many days are pruned. Each entity's live row (`end_transaction_id IS NULL`) is always preserved, as are the live rows of its children and associations; closed historical rows (including the baseline) age out. Set to `0` or a negative value to disable pruning. |
+
+The task ships in the default `CeleryConfig.beat_schedule`; a deployment that overrides `CELERY_CONFIG` without inheriting the default will log a startup warning that the prune task is absent (so it never silently stops running). Retention only prunes whatever history exists — capture itself is gated separately by `ENABLE_VERSIONING_CAPTURE` (ships off).
+
+### Webhook alerts/reports block private/internal hosts by default
+
+Webhook alert/report dispatch (`WebhookNotification.send`) now validates the target URL's host against the same private/internal-IP block applied to dataset import URLs. If the resolved host is in a loopback, link-local, private (RFC-1918), shared-CGNAT, or multicast range, the webhook is rejected with `NotificationParamException`.
+
+Deployments that intentionally point webhooks at internal targets (chatops bridges, internal automation servers, on-premises Mattermost/Rocket.Chat, etc.) can opt out by setting `ALERT_REPORTS_WEBHOOK_ALLOW_INTERNAL_HOSTS = True` in `superset_config.py`. This mirrors the existing `DATASET_IMPORT_ALLOW_INTERNAL_DATA_URLS` opt-out for dataset imports.
+
+### Impala cancel_query blocks private/internal hosts by default
+
+The Impala engine spec's `cancel_query` issues an HTTP request from the Superset backend to the host configured on the Impala database connection. That host is now validated before the request: if it resolves to a private/internal IP range, the cancel call is refused and a warning is logged. Operators whose Impala cluster runs on an internal network can opt out by setting `IMPALA_CANCEL_QUERY_ALLOW_INTERNAL_HOSTS = True` in `superset_config.py`. This mirrors the dataset-import and webhook opt-out flags.
+
+### Map chart renderer and OpenStreetMap migration behavior
+
+The MapLibre migration for deck.gl charts preserves saved non-Mapbox styles on
+the MapLibre-compatible path. Saved styles such as OpenStreetMap, `tile://`
+tile templates, generic HTTPS style URLs, and charts without a saved style are
+not reclassified as Mapbox during migration and do not require
+`MAPBOX_API_KEY` only because of the migration.
+
+Saved true Mapbox styles whose value starts with `mapbox://` remain
+Mapbox-backed. If a Superset deployment does not configure `MAPBOX_API_KEY`,
+those saved Mapbox charts keep the existing missing-key message instead of
+silently falling back to MapLibre or another provider. In Explore, deck.gl and
+point-cluster renderer controls preserve saved Mapbox state, but the Mapbox
+choice is not available as a new working renderer without a configured key.
+
+The MapLibre style choices include `Streets (OSM)`, backed by
+`https://tile.openstreetmap.org/{z}/{x}/{y}.png`. This OpenStreetMap tile
+service requires visible `© OpenStreetMap contributors` attribution and should
+be used through normal browser map tile requests and caching; it is not intended
+for bulk prefetch or offline tile downloads.
+
+### Password complexity policy enabled by default
+
+Superset now ships a default password-complexity policy, enforced (via Flask-AppBuilder) across self-registration, the user create/edit/reset forms, and the User REST API. The policy requires a minimum password length of 8 characters and rejects a built-in blocklist of common/guessable passwords.
+
+This is enabled by default (`FAB_PASSWORD_COMPLEXITY_ENABLED = True`), so new or reset passwords that are too short or appear in the blocklist will be rejected where they were previously accepted. Existing stored passwords are unaffected until they are next changed.
+
+Operators can tune or disable the policy via config:
+
+- `AUTH_PASSWORD_MIN_LENGTH` — minimum length (default `8`).
+- `AUTH_PASSWORD_COMMON_BLOCKLIST` — extra passwords to reject, in addition to the built-in list.
+- `FAB_PASSWORD_COMPLEXITY_VALIDATOR` — replace with your own callable for custom rules.
+- `FAB_PASSWORD_COMPLEXITY_ENABLED = False` — disable enforcement entirely.
+
+### Data uploads bounded by UPLOAD_MAX_FILE_SIZE_BYTES
+
+Single data-file uploads (CSV, Excel, columnar) are now bounded by the `UPLOAD_MAX_FILE_SIZE_BYTES` config option, which defaults to `100 * 1024 * 1024` (100 MB). Files larger than this are rejected with a `413` before their contents are buffered into memory. Set `UPLOAD_MAX_FILE_SIZE_BYTES = None` to disable the check and restore unbounded uploads.
+### Currency symbol position follows the locale when unset
+
+When a chart's currency control leaves the **Prefix or suffix** field empty, the currency symbol position is now derived from the deployment locale's own convention via `Intl.NumberFormat` instead of always defaulting to a suffix. For example, under the default `en-US` locale `USD`, `GBP`, and `EUR` render as a prefix (`$ 1,000`), while eurozone locales such as `fr-FR` render `EUR` as a suffix (`1 000 €`). An explicit Prefix/Suffix selection is always honored and is unaffected.
+
+Charts that relied on the previous always-suffix default for an unset position will render the symbol on the locale-appropriate side instead; set the position explicitly on the metric's currency control to pin it.
+
+### Duration formatter precision
+
+The `DURATION` number formatter now uses `Intl.DurationFormat` for locale-aware output. By default, sub-second fields are omitted, so values that previously displayed fractional seconds with `pretty-ms`, such as `10500` milliseconds rendering as `10.5s`, now render as `10s`.
+
+To preserve sub-second precision in custom duration formatters, enable `formatSubMilliseconds`.
+
+### Cache warmup authenticates via SUPERSET_CACHE_WARMUP_USER
+
+The `cache-warmup` Celery task now drives a real WebDriver session for reliable authentication and reads the user to authenticate as from the new `SUPERSET_CACHE_WARMUP_USER` config option. It no longer consults `CACHE_WARMUP_EXECUTORS` for the warmup path. `SUPERSET_CACHE_WARMUP_USER` defaults to `None`, so the task fails fast with a clear message until you set it. Operators who previously relied on `CACHE_WARMUP_EXECUTORS` for cache warmup must set `SUPERSET_CACHE_WARMUP_USER` to a dedicated least-privilege user with access to the dashboards they want warmed up before the next warmup run.
+
+### YDB now uses a native sqlglot dialect
+
+YDB SQL parsing now relies on the dedicated [`ydb-sqlglot-plugin`](https://pypi.org/project/ydb-sqlglot-plugin/) dialect, which registers itself with sqlglot automatically. YDB users must install this plugin (e.g., via `pip install "apache-superset[ydb]"`) to avoid a `ValueError` when Superset parses YDB queries.
+
+### Embedded dashboards enforce configured Allowed Domains for postMessage
+
+The embedded dashboard page now validates the origin of incoming `postMessage` events against the dashboard's configured **Allowed Domains**. The server-rendered embedded page exposes the configured domains in its bootstrap payload, and the frontend rejects message events whose origin is not in that list.
+
+Enforcement only applies when the Allowed Domains list is non-empty. If the list is empty (the default), any origin is accepted, so there is no behavior change for embeds that did not configure Allowed Domains.
+
+### Default guest/async JWT secrets are rejected at startup
+
+Superset already refuses to start in production (non-debug, non-testing) when `SECRET_KEY` is left at its built-in default, and when `GUEST_TOKEN_JWT_SECRET` is left at its default while `EMBEDDED_SUPERSET` is enabled. This behavior is extended to `GLOBAL_ASYNC_QUERIES_JWT_SECRET`: if the `GLOBAL_ASYNC_QUERIES` feature flag is enabled and the secret is still the publicly known default (`test-secret-change-me`), Superset logs a clear error and refuses to start.
+
+As with the existing `SECRET_KEY` check, this only fails in production. In debug mode, testing mode, or under the test runner, a warning is logged instead of exiting, so local development is unaffected.
+
+To resolve the error, set a strong random value in `superset_config.py`:
+
+```python
+GLOBAL_ASYNC_QUERIES_JWT_SECRET = "<output of: openssl rand -base64 42>"
+```
+
+The check is only active when the relevant feature is enabled, so deployments that do not use global async queries (or embedding) are not affected.
+
+### Guest token revocation (opt-in)
+
+Embedded guest tokens can be coarsely revoked at runtime via a new opt-in mechanism. A new config flag `GUEST_TOKEN_REVOCATION_ENABLED` (default `False`) gates the feature. When enabled, every minted guest token carries a revocation version, and tokens whose version is below the current expected version (stored in the metadata database) are rejected at validation time.
+
+Bump the expected version with the new CLI command to invalidate all outstanding guest tokens:
+
+```bash
+superset revoke-guest-tokens
+```
+
+This change is backward compatible. The feature is off by default, and even when enabled nothing is revoked until an admin explicitly bumps the version: the expected version starts at `0`, and tokens minted before this change (which carry no version claim) are treated as version `0`. No database migration is required.
+
+### Sessions are terminated when an account is disabled
+
+Disabling a user account (setting `active` to `False`, via the admin UI, REST API, or CLI) now terminates that user's outstanding sessions on their next request, instead of relying on a passive check. This works for both client-side cookie sessions and server-side session stores via a per-user invalidation epoch (`user_attribute.sessions_invalidated_at`, added by a migration). The mechanism is inert for users that were never disabled (NULL epoch), so there is no behavior change for active users. Re-enabling an account and logging in again starts a fresh, valid session. The migration backfills the epoch for accounts that are already disabled at upgrade time, so re-enabling such an account does not revive a session that predates this feature.
+
+### Opt-in SSH tunnel server host key verification
+
+SSH tunnels can now optionally pin the expected SSH server host key as a defense-in-depth measure against man-in-the-middle attacks. paramiko's transport performs no known-hosts checking by default, so previously the SSH server's identity was not verified. This feature is opt-in and off by default; existing tunnels are unaffected.
+
+- A new nullable `server_host_key` column on the `ssh_tunnels` table stores the expected host key in authorized-key form (e.g. `ssh-ed25519 AAAA...`). It is a public key and is stored in plaintext. It can be set via the SSH tunnel POST/PUT payloads (`ssh_tunnel.server_host_key`).
+- When a tunnel has `server_host_key` set, Superset connects to the SSH server, reads the host key it presents, and rejects the tunnel if it does not match.
+- A new config flag `SSH_TUNNEL_STRICT_HOST_KEY_CHECKING` (default `False`) controls fail-closed behavior. When `True`, every tunnel must declare a `server_host_key`; a tunnel without one is rejected.
+
+Runbook to adopt:
+
+1. Capture the SSH server's host key, e.g. `ssh-keyscan -t ed25519 ssh.example.com` (verify it out-of-band).
+2. Set that value on the tunnel's `server_host_key` (via the database/SSH tunnel API or UI payload).
+3. Optionally set `SSH_TUNNEL_STRICT_HOST_KEY_CHECKING = True` in `superset_config.py` to require host-key verification on all tunnels.
+
+### SMTP server certificate validation enabled by default
+
+`SMTP_SSL_SERVER_AUTH` now defaults to `True` (previously `False`). With this default, STARTTLS/SSL connections to the configured SMTP server validate the server's TLS certificate against the system trusted CA store. This makes outbound email (alerts and reports) verify the mail server's identity out of the box.
+
+If your SMTP server presents a self-signed certificate, or a certificate that is not trusted by the system CA store, email delivery may now fail with a certificate verification error. To restore the previous behavior of skipping certificate validation, set the following in `superset_config.py`:
+
+```python
+SMTP_SSL_SERVER_AUTH = False
+```
+
+The recommended fix is to add the SMTP server's certificate (or its issuing CA) to the system trust store rather than disabling validation.
+
+### Dataset import validates catalog against the target connection
+
+Importing a dataset now validates the `catalog` field against the target database connection. When the connection has multi-catalog disabled (`allow_multi_catalog` off) and the dataset's catalog is not the connection's default catalog, the import fails instead of silently persisting the non-default catalog. This matches the validation already enforced on the dataset update path and prevents imported datasets from querying an unintended database.
+
+If you relied on importing datasets with a non-default catalog, enable "Allow changing catalogs" on the target connection, or set the dataset's catalog to the connection's default before importing.
+
+### Extension supply-chain controls (denylist + version policy)
+
+Two opt-in static gates control which extensions are allowed to load:
+
+- `EXTENSION_DENYLIST` refuses extensions matching an id (every version) or `id@version` (a single version), e.g. `["compromised-extension", "other-ext@1.2.3"]`.
+- `EXTENSION_VERSION_POLICY` enforces a minimum version per extension id, e.g. `{"acme.widget": "1.2.0"}` (PEP 440 comparison); a release below the minimum is refused.
+
+Both default to empty (no behavior change). They apply to both the `LOCAL_EXTENSIONS` and `EXTENSIONS_PATH` load paths.
+
+### Dynamic Group By respects the sort toggle for display values
+
+The Dynamic Group By chart customization now orders its display values according to the "Sort display control values" toggle: ascending (A–Z), descending (Z–A), or the dataset's source order when the toggle is unset. Previously the dropdown always sorted alphabetically. Existing dashboards where the toggle was never set will show options in source order instead of A–Z; open the customization and enable the toggle to restore alphabetical ordering.
+
+### Selectable encryption engine for app-encrypted fields (AES-GCM)
+
+App-encrypted fields (database passwords, SSH tunnel credentials, OAuth tokens, etc.) can now use authenticated **AES-GCM** encryption instead of the historical unauthenticated **AES-CBC**. A new config selects the engine for the default adapter:
+
+```python
+# "aes" (AES-CBC, historical default) | "aes-gcm" (authenticated, recommended for new installs)
+SQLALCHEMY_ENCRYPTED_FIELD_ENGINE = "aes"
+```
+
+**No action required / no behavior change:** the default remains `"aes"`, so existing installs are unaffected.
+
+**Opting in on an existing install:** flipping the engine on a populated database without re-encrypting first will make stored secrets undecryptable, because the two ciphertext formats are not compatible. A migrator is provided. Recommended runbook:
+
+1. Take a metadata-DB backup.
+2. Re-encrypt existing secrets into the new engine (the `SECRET_KEY` is unchanged):
+   ```bash
+   superset re-encrypt-secrets --engine aes-gcm
+   ```
+3. Set `SQLALCHEMY_ENCRYPTED_FIELD_ENGINE = "aes-gcm"` in your config.
+4. Restart Superset.
+5. Re-run the migrator once more after the restart:
+   ```bash
+   superset re-encrypt-secrets --engine aes-gcm
+   ```
+   A live instance keeps writing *new* secrets as AES-CBC during the window between step 2 and the restart in step 4; this second pass sweeps those up (it is idempotent, so already-migrated values are skipped).
+
+Schedule the cutover in a quiet window. Runtime reads use only the single configured engine, so in a multi-worker deployment there is an unavoidable brief decrypt-outage between the migration commit and the last worker restarting with the new config — each migrator run is transactional, but the fleet-wide cutover is not zero-downtime.
+
+The migration is transactional (all-or-nothing) and idempotent — it can be safely re-run or resumed. Note that AES-GCM, unlike AES-CBC, does not support querying directly over encrypted columns; audit any code that filters on an encrypted column before switching. See the SIP at `docs/sip/authenticated-encryption-at-rest.md` for details.
+
+### Soft delete and restore for datasets
+
+**The soft-delete behavior in this section applies only when the `SOFT_DELETE` feature flag is enabled. The flag defaults to `False`** (`@lifecycle: development`), so on a default deployment `DELETE /api/v1/dataset/<id>` continues to **hard-delete permanently** — nothing is recoverable. Enable `SOFT_DELETE` to get the behavior described below.
+
+**Flag-toggle caveat:** the soft-delete visibility filter is evaluated per query while the flag is on. If datasets are soft-deleted during a flag-on window and the flag is later turned **off**, those rows reappear as live datasets in all lists, lookups, and relationship loads (including charts that reference them). The `POST /<uuid>/restore` endpoint and the `dataset_deleted_state` list filter remain functional regardless of the flag, deliberately, so rows soft-deleted during a flag-on window stay discoverable and restorable after a rollback of the flag.
+
+**Flag-independent parts of this work** (active even with `SOFT_DELETE` off): the restore endpoint and deleted-state filter (above); the database-deletion guard counting soft-deleted datasets; the `get_or_create_dataset` soft-deleted-twin pre-check; the combined datasource listing (`GET /api/v1/datasource/...`) always excluding soft-deleted datasets; and the two uniqueness-validation changes documented at the end of this section. Everything else — the soft DELETE itself and the visibility filtering — is flag-gated.
+
+With the flag enabled: `DELETE /api/v1/dataset/<id>` no longer hard-deletes the dataset (the bulk-delete endpoint behaves the same way). The row is marked with a `deleted_at` timestamp and hidden from all list, detail, and lookup endpoints. Datasets in this state are excluded from default queries and from relationship loads (e.g. `database.tables`).
+
+**No cascade in v1.** Soft-delete does not propagate to dependent charts or dashboards: they remain visible. Loading a chart whose dataset is soft-deleted surfaces a "datasource not found" error at chart-load time. Restore the dataset to recover.
+
+**Database deletion is blocked by soft-deleted datasets.** Superset already refuses to delete a database that still has datasets (`DatabaseDeleteDatasetsExistFailedError`); that check now explicitly counts soft-deleted datasets too (it bypasses the visibility filter), since the soft-deleted `tables` rows still reference the database via `database_id` and must not be orphaned. Consequence: because dataset `DELETE` is soft and v1 ships no hard-delete/purge, **a database that has ever had datasets cannot be deleted through the API once those datasets are soft-deleted** — the rows remain and keep blocking the delete. Until a purge capability lands, operators who must remove such a database have to hard-delete the underlying `tables` rows out-of-band first. This is a deliberate trade-off (no orphaned rows / restorable datasets) and is expected to be resolved by the planned purge work.
+
+**Side-effect change for operators.** Because the row is no longer physically deleted, FAB `ab_view_menu` / permission-view rows tied to the dataset are also preserved. Downstream automation that relied on `DELETE /api/v1/dataset/<id>` cleaning up those rows must now react to the new `POST /api/v1/dataset/<uuid>/restore` lifecycle, or call the eventual hard-delete endpoint.
+
+**New endpoint** — `POST /api/v1/dataset/<uuid>/restore` clears `deleted_at` and returns the dataset to active state. Requires `can_write on Dataset` and editorship of the row (or admin). Soft-deleted datasets can also be surfaced in the list endpoint via the new `dataset_deleted_state` rison filter: `include` returns both live and soft-deleted rows, `only` returns just the soft-deleted ones. Any other value is ignored. For non-admin users, soft-deleted rows are limited to datasets they can edit — the same audience that can restore them.
+
+**Permissions migration:** existing role grants of `can_write on Dataset` cover the new restore endpoint automatically; no role migration is required.
+
+**Schema migration:** the migration adds a nullable `deleted_at` column and an index on it (`ix_tables_deleted_at`) to the `tables` table. The column add is instant; the index build runs inline (no `CONCURRENTLY`) and may briefly block writes on the `tables` table (INSERT/UPDATE/DELETE are queued while the index builds; reads are unaffected) on large Postgres deployments. MySQL InnoDB builds the index online (no blocking). Production deployments with many thousands of datasets should run this migration during a maintenance window.
+
+**Rollback note:** if the application code is rolled back after datasets have been soft-deleted, the older code path's visibility filter no longer applies and previously hidden rows become visible to the older code. Pair the rollback with a data decision (restore the rows, hard-delete them, or also downgrade the migration) rather than assuming the old hard-delete semantics still hold. **Downgrading the migration destroys the deletion markers**: `downgrade()` drops the `deleted_at` column, so any not-yet-restored soft-deleted datasets silently become live, active datasets with no record they were ever deleted. Reconcile the trash (restore or hard-delete each row) *before* downgrading, and disable the `SOFT_DELETE` flag first so no new soft deletes land mid-rollback.
+
+**SQL Lab / dataset-creation flows:** creating a dataset over a table whose dataset sits in the trash is refused. The SQL Lab "save as dataset" flow (`get_or_create_dataset`) and file uploads return a **422 naming the hidden twin and the restore endpoint**; the plain create, update, and duplicate paths currently fail with the generic "already exists" 422. In all cases the remediation is the same: restore the hidden dataset (or use a different table name). Perm-string maintenance also covers hidden rows: renaming a database rewrites `perm`/`schema_perm`/`catalog_perm` on soft-deleted datasets and their charts, so a later restore does not resurrect stale permission strings.
+
+**Importer behavior:** importing a dataset YAML whose UUID matches an existing **soft-deleted** dataset is treated as an implicit restore-with-update — **and this happens even when `overwrite` is not set**. This is a deliberate asymmetry with active rows: an active dataset imported without `overwrite=true` is returned unchanged, but a soft-deleted UUID match is restored *and* has the upload's contents applied regardless of the `overwrite` argument, on the reasoning that re-importing a deleted dataset's exact UUID is an explicit request to bring it back. The restore preserves the original PK, the chart back-reference, `table_columns`, and `sql_metrics`. Non-editors get `ImportFailedError`. Callers without `can_write` get `ImportFailedError` instead of silently receiving the soft-deleted row.
+
+**Uniqueness-validation changes that apply regardless of the feature flag:** two dataset uniqueness checks were tightened alongside this work and are active even with `SOFT_DELETE` off. (1) Create/update uniqueness treats a dataset whose `catalog` is `NULL` as belonging to the database's default catalog, so a legacy twin pair (`catalog=NULL` vs. `catalog=<default>`, same database/schema/name) that older versions allowed now fails validation with "already exists" when either row is edited — resolve by renaming or removing one of the twins. (2) Duplicating a dataset now checks name collisions scoped to the target (database, catalog, schema) instead of globally by name alone: duplicates into other databases that were previously blocked are now allowed.
+
+### Soft delete and restore for charts
+
+**Everything in this section applies only when the `SOFT_DELETE` feature flag is enabled. The flag defaults to `False`** (`@lifecycle: development`), so on a default deployment `DELETE /api/v1/chart/<id>` continues to **hard-delete permanently** — nothing is recoverable. Enable `SOFT_DELETE` to get the behavior described below.
+
+**Flag-toggle caveat:** the soft-delete visibility filter is evaluated per query while the flag is on. If charts are soft-deleted during a flag-on window and the flag is later turned **off**, those rows reappear as live charts in all lists, lookups, and relationship loads (including dashboards that contained them). The `POST /<uuid>/restore` endpoint and the `chart_deleted_state` list filter remain functional regardless of the flag, deliberately, so rows soft-deleted during a flag-on window stay discoverable and restorable after a rollback of the flag.
+
+With the flag enabled: `DELETE /api/v1/chart/<id>` no longer hard-deletes the chart (the bulk-delete endpoint behaves the same way). The row is marked with a `deleted_at` timestamp and hidden from all list, detail, and lookup endpoints. Charts in this state are excluded from default queries and from relationship loads (e.g. `dashboard.slices`).
+
+**Operational notes:** a report schedule whose target chart is soft-deleted now fails its runs with an explicit error ("The chart this report targets was deleted...") until the chart is restored or the report re-pointed — chart deletion is blocked while a report references the chart, but a validate/commit race or a flag toggle can still produce this state. Dashboards **preserve** their membership rows for soft-deleted charts: saving a dashboard does not sever a trashed member, and restoring the chart re-attaches it to its dashboards.
+
+**New endpoint** — `POST /api/v1/chart/<uuid>/restore` clears `deleted_at` and returns the chart to active state. Requires `can_write on Chart` and editorship of the row (or admin). Soft-deleted charts can also be surfaced in the list endpoint via the new `chart_deleted_state` rison filter: `include` returns both live and soft-deleted rows, `only` returns just the soft-deleted ones.

+
+**Permissions migration:** existing role grants of `can_write on Chart` cover the new restore endpoint automatically; no role migration is required.
+
+**Schema migration:** the migration adds a nullable `deleted_at` column and an index on it (`ix_slices_deleted_at`) to the `slices` table.

The restore preserves the original PK and all out-of-archive references (`dashboard_slices` junctions, `report.chart_id`, tag rows). The operation is permission-gated: non-editors get `ImportFailedError`, and callers without `can_write` get `ImportFailedError` instead of silently receiving the soft-deleted row.
+
+- [39914](https://github.com/apache/superset/pull/39914) `ALERT_REPORT_SLACK_V2` now defaults to `True` and the legacy Slack v1 integration (`Slack` recipient type, `files.upload` API) is deprecated for removal in the next major. Slack blocked new apps from `files.upload` in May 2024 and fully retired the method for all apps on November 12, 2025; because the v1 path sends files through `files.upload`, v1 file-bearing sends now fail at the API level — only text-only `chat_postMessage` still works via the legacy path. Grant your Slack bot the `channels:read` and `groups:read` scopes so existing `Slack` recipients can be auto-upgraded to `SlackV2` on next send. Operators who explicitly override the flag to `False`, or whose Slack bot is missing those scopes, will see deprecation warnings while text-only sends continue through the legacy path.
+
+### Soft delete and restore for dashboards
+
+**Everything in this section applies only when the `SOFT_DELETE` feature flag is enabled. The flag defaults to `False`** (`@lifecycle: development`), so on a default deployment `DELETE /api/v1/dashboard/<id>` continues to **hard-delete permanently** — nothing is recoverable. Enable `SOFT_DELETE` to get the behavior described below.
+
+**Flag-toggle caveat:** the soft-delete visibility filter is evaluated per query while the flag is on. If dashboards are soft-deleted during a flag-on window and the flag is later turned **off**, those rows reappear as live dashboards in all lists and lookups (including slug lookups — if a soft-deleted dashboard's slug was reused while the flag was on, both rows become visible with the same slug). The `POST /<uuid>/restore` endpoint and the `dashboard_deleted_state` list filter remain functional regardless of the flag, deliberately, so rows soft-deleted during a flag-on window stay discoverable and restorable after a rollback of the flag.
+
+With the flag enabled: `DELETE /api/v1/dashboard/<id>` no longer hard-deletes the dashboard (the bulk-delete endpoint behaves the same way). The row is marked with a `deleted_at` timestamp and hidden from the dashboard API's list, detail, and lookup endpoints, which return 404 for soft-deleted dashboards. The embedded-dashboard iframe URL (`/embedded/<uuid>`) keeps rendering because it reads only `embedded.allowed_domains` and `embedded.dashboard_id` (the FK column) without dereferencing the parent dashboard; the frontend's subsequent dashboard-API fetch is what sees the 404 and surfaces "dashboard not found" to the user.
+
+**New endpoint** — `POST /api/v1/dashboard/<uuid>/restore` clears `deleted_at` and returns the dashboard to active state. Requires `can_write on Dashboard` and editorship of the row (or admin). Soft-deleted dashboards can also be surfaced in the list endpoint via the new `dashboard_deleted_state` rison filter: `include` returns both live and soft-deleted rows, `only` returns just the soft-deleted ones. Any other value is ignored. For non-admin users, soft-deleted rows are limited to dashboards they can edit — the same audience that can restore them.
+
+**Permissions migration:** existing role grants of `can_write on Dashboard` cover the new restore endpoint automatically; no role migration is required.
+
+**Schema migration:** the migration adds a nullable `deleted_at` column and an index on it (`ix_dashboards_deleted_at`) to the `dashboards` table, and **replaces the full unique constraint on `slug`** with a partial unique index (`ix_dashboards_active_slug`) enforcing slug uniqueness only among active (non-soft-deleted) rows. The column add is instant. On Postgres the constraint swap briefly blocks reads and writes during `ALTER TABLE ... DROP CONSTRAINT` (acquires `ACCESS EXCLUSIVE`), then blocks writes only during `CREATE UNIQUE INDEX` (acquires `ShareLock`); reads pass through during the index build. Both windows are sub-second on a typical `dashboards` table. MySQL InnoDB builds the functional index online (no blocking).
+
+**Rollback note:** the downgrade restores the original full unique constraint on `slug`. If the partial-index window allowed slug reuse (a soft-deleted row and an active row holding the same slug), `ALTER TABLE ... ADD CONSTRAINT idx_unique_slug UNIQUE (slug)` will abort with a unique-constraint violation. Before downgrading, hard-delete the soft-deleted duplicates (or rename one side) so each slug appears at most once across all rows. Rolling back the application code while leaving the new migration in place is also possible but exposes soft-deleted rows to the older code path; pair the rollback with a data decision (restore, hard-delete, or migrate-down).
+
+The partial-index replacement is dialect-dependent: PostgreSQL uses a native `WHERE deleted_at IS NULL` partial index; MySQL 8.0.13+ uses a functional index over `(CASE WHEN deleted_at IS NULL THEN slug END)` (8.0.13 is the first release with functional key parts). **MySQL <8.0.13, MariaDB, and SQLite keep the original full unique constraint** (functional indexes / column-level UNIQUE recreation aren't supported cleanly — MariaDB is excluded even at 10.x because its `CASE`-expression index semantics differ), so on those backends a soft-deleted dashboard continues to reserve its slug for the lifetime of the row.
+
+**Slug semantics:** on PostgreSQL and MySQL 8.0.13+, the slug of a soft-deleted dashboard is **free for reuse**. A new active dashboard can claim it immediately. Restoring a soft-deleted dashboard whose slug has since been claimed returns **422 with a clean error** (`DashboardSlugConflictError`) — rename one of the dashboards and retry; the restore is not silently rejected by a database-level constraint violation.
+
+**Importer behavior:** importing a dashboard YAML whose UUID matches an existing **soft-deleted** dashboard is treated as an implicit restore-with-update — **and this happens even when `overwrite` is not set**. This is a deliberate asymmetry with active rows: an active dashboard imported without `overwrite=true` is returned unchanged (the import never mutates it), but a soft-deleted UUID match is restored *and* has the upload's contents applied regardless of the `overwrite` argument, on the reasoning that re-importing a deleted dashboard's exact UUID is an explicit request to bring it back. The restore preserves the original PK and all pre-deletion relationship rows (`dashboard_slices` junctions, editor/viewer subjects, tags). Callers whose imports must never mutate existing state should treat bundles that may contain previously deleted UUIDs accordingly. The operation is permission-gated: it requires `can_write` and editorship of the deleted row (or admin) — non-editors get `ImportFailedError`, and callers without `can_write` get `ImportFailedError` instead of silently receiving the soft-deleted row.
+
+### Engine spec capability flag: `supports_offset`
+
+A new `BaseEngineSpec.supports_offset` attribute (default `True`) indicates whether a database engine supports the SQL `OFFSET` clause. Engines that do not support `OFFSET` — such as Elasticsearch SQL and OpenDistro — opt out by setting it to `False`, and Superset uses each engine's cursor API to paginate drill-to-detail samples instead of emitting `OFFSET`. Downstream forks maintaining custom engine specs may set the flag to `False` (and implement `fetch_data_with_cursor`) to avoid crashes when paginated drill-to-detail queries are run against engines without `OFFSET` support.
+
+**Note on deep-pagination cost:** Cursor-based engines (including Elasticsearch and OpenDistro) are forward-only, so reaching page `N` of a drill-to-detail view issues `N` round trips to the cluster. Deep pagination is therefore linear in page number; users paginating into the hundreds or thousands will notice added latency compared to `OFFSET`-capable engines.
+
+### Granular Export Controls
+
+A new feature flag `GRANULAR_EXPORT_CONTROLS` introduces three fine-grained permissions that replace the legacy `can_csv` permission:
+
+| Permission | Controls |
+|---|---|
+| `can_export_data` | CSV, Excel, JSON exports |
+| `can_export_image` | Screenshot/PDF exports |
+| `can_copy_clipboard` | Copy-to-clipboard operations |
+
+When the feature flag is enabled, these permissions are enforced on both the frontend (disabled buttons with tooltips) and backend (403 responses from API endpoints). When disabled, legacy `can_csv` behavior is preserved.
+
+**Migration behavior:** All three new permissions are granted to every role that currently has `can_csv`, preserving existing access. Admins can then selectively revoke individual export permissions from specific roles as needed.
+
+### Deck.gl MapBox viewport and opacity controls are functional
+
+The Deck.gl MapBox chart's **Opacity**, **Default longitude**, **Default latitude**, and **Zoom** controls were previously non-functional — changing them had no effect on the rendered map. These controls are now wired up correctly.
+
+**Behavior change for existing charts:** Previously, the viewport controls had hard-coded default values (`-122.405293`, `37.772123`, zoom `11` — San Francisco) that were stored in each chart's `form_data` but never applied. The map always used `fitBounds` to center on the data. With this fix, those stored values are now respected, which means existing MapBox charts may open centered on the old default coordinates instead of fitting to data bounds.
+
+**To restore fit-to-data behavior:** Open the chart in Explore, clear the **Default longitude**, **Default latitude**, and **Zoom** fields in the Viewport section, and re-save the chart.
+
+### Combined datasource list endpoint

+Added a new combined datasource list endpoint at `GET /api/v1/datasource/` to serve datasets and semantic views in one response.
+
+- The endpoint is available to users with at least one of `can_read` on `Dataset` or `SemanticView`.
+- Semantic views are included only when the `SEMANTIC_LAYERS` feature flag is enabled.
+- The endpoint enforces strict `order_column` validation and returns `400` for invalid sort columns.

+### ClickHouse minimum driver version bump
+
+The minimum required version of `clickhouse-connect` has been raised to `>=0.13.0`. If you are using the ClickHouse connector, please upgrade your `clickhouse-connect` package. The `_mutate_label` workaround that appended hash suffixes to column aliases has also been removed, as it is no longer needed with modern versions of the driver.
+
+### Kenya Country Map: Updated Administrative Divisions
+
+The Kenya country map has been updated to reflect the 47 counties established under Kenya's 2010 constitution, replacing the outdated 8-province boundaries from the Natural Earth dataset. County keys now use ISO 3166-2:KE codes (`KE-01` through `KE-47`), replacing the former province codes (`KE-110`, `KE-200`, ..., `KE-800`). Dashboards that join on the old province codes will need to re-key their datasets to use the new county codes.
+
+### MCP Tool Observability
+
+MCP (Model Context Protocol) tools now include enhanced observability instrumentation for monitoring and debugging:
+
+**Two-layer instrumentation:**
+1. **Middleware layer** (`LoggingMiddleware`): Automatically logs all MCP tool calls with `duration_ms` and `success` status in the audit log (Action Log UI, logs table)
+2. **Sub-operation tracking**: All 19 MCP tools include granular `event_logger.log_context()` blocks for tracking individual operations like validation, database writes, and query execution
+
+**Action naming convention:**
+- Tool-level logs: `mcp_tool_call` (via middleware)
+- Sub-operation logs: `mcp.{tool_name}.{operation}` (e.g., `mcp.generate_chart.validation`, `mcp.execute_sql.query_execution`)
+
+**Querying MCP logs:**
+```sql
+-- Top slowest MCP operations
+SELECT action, COUNT(*) as calls, AVG(duration_ms) as avg_ms
+FROM logs
+WHERE action LIKE 'mcp.%'
+GROUP BY action
+ORDER BY avg_ms DESC
+LIMIT 20;
+
+-- MCP tool success rate
+SELECT
+    json_extract(curated_payload, '$.tool') as tool,
+    COUNT(*) as total_calls,
+    SUM(CASE WHEN json_extract(curated_payload, '$.success') = 'true' THEN 1 ELSE 0 END) as successful,
+    ROUND(100.0 * SUM(CASE WHEN json_extract(curated_payload, '$.success') = 'true' THEN 1 ELSE 0 END) / COUNT(*), 2) as success_rate
+FROM logs
+WHERE action = 'mcp_tool_call'
+GROUP BY tool
+ORDER BY total_calls DESC;
+```
+
+**Security note:** Sensitive parameters (passwords, API keys, tokens) are automatically redacted in logs as `[REDACTED]`.
+
+### Distributed Coordination Backend
+
+A new `DISTRIBUTED_COORDINATION_CONFIG` configuration provides a unified Redis-based backend for real-time coordination features in Superset. This backend enables:
+
+- **Pub/sub messaging** for real-time event notifications between workers
+- **Atomic distributed locking** using Redis SET NX EX (more performant than database-backed locks)
+- **Event-based coordination** for background task management
+
+The distributed coordination is used by the Global Task Framework (GTF) for abort notifications and task completion signaling, and will eventually replace `GLOBAL_ASYNC_QUERIES_CACHE_BACKEND` as the standard signaling backend. Configuring this is recommended for Redis enabled production deployments.
+
+Example configuration in `superset_config.py`:
+```python
+DISTRIBUTED_COORDINATION_CONFIG = {
+    "CACHE_TYPE": "RedisCache",
+    "CACHE_KEY_PREFIX": "signal_",
+    "CACHE_REDIS_URL": "redis://localhost:6379/1",
+    "CACHE_DEFAULT_TIMEOUT": 300,
+}
+```
+
+See `superset/config.py` for complete configuration options.

 ### WebSocket config for GAQ with Docker
 
 [35896](https://github.com/apache/superset/pull/35896) and [37624](https://github.com/apache/superset/pull/37624) updated documentation on how to run and configure Superset with Docker. Specifically for the WebSocket configuration, a new `docker/superset-websocket/config.example.json` was added to the repo, so that users could copy it to create a `docker/superset-websocket/config.json` file. The existing `docker/superset-websocket/config.json` was removed and git-ignored, so if you're using GAQ / WebSocket make sure to:

+### Composite primary keys on many-to-many association tables
+
+Eight M:N association tables move from a synthetic `id INTEGER PRIMARY KEY` to a composite `PRIMARY KEY (fk1, fk2)` on their two foreign-key columns. The surrogate `id` is dropped, and the redundant `UNIQUE (fk1, fk2)` on the two tables that carried one is removed (now subsumed by the PK).
+
+| Table | Composite PK |
+|---|---|
+| `dashboard_roles` | `(dashboard_id, role_id)` |
+| `dashboard_slices` | `(dashboard_id, slice_id)` |
+| `dashboard_user` | `(user_id, dashboard_id)` |
+| `report_schedule_user` | `(user_id, report_schedule_id)` |
+| `rls_filter_roles` | `(role_id, rls_filter_id)` |
+| `rls_filter_tables` | `(table_id, rls_filter_id)` |
+| `slice_user` | `(user_id, slice_id)` |
+| `sqlatable_user` | `(user_id, table_id)` |
+
+**Before upgrading:**
+
+- The migration **deletes** two classes of pre-existing rows the composite PK cannot accommodate: duplicate `(fk1, fk2)` pairs (it keeps the lowest `id` and removes the rest) and rows with `NULL` in either FK column. Both are meaningless for `secondary=` association tables, but export the affected rows first if you need an audit record.
+- External tooling (BI tools, backup scripts) that references the surrogate `id` on these tables will break; no application code references it.
+- Downgrade restores the `id` column (and the original `UNIQUE` on the two tables that had it) but leaves the FK columns `NOT NULL` (intentional — a `NULL` FK in a junction row is meaningless).
+
+For large `dashboard_slices` / `report_schedule_user` tables, see the operator runbook in [#39859](https://github.com/apache/superset/pull/39859) — pre-flight inventory queries, per-dialect lock-window sizing, and the duplicate / NULL-FK roll-up — to plan the maintenance window.

+#### Before You Cut
+
+The cut snapshots whatever's on disk into a frozen historical version, including auto-generated content (database pages from `superset/db_engine_specs/`, API reference from `static/resources/openapi.json`, component pages from Storybook stories). The cut script refreshes these via `generate:smart` before snapshotting, but the **`databases.json` diagnostics file** needs special care to capture full detail:
+
+1. **Canonical release cut**: download the `database-diagnostics` artifact from a green `Python-Integration` run on master, place it at `docs/src/data/databases.json`, then run the cut script with `--skip-generate` to preserve it. This is what the production deploy uses and includes full Flask-context diagnostics (driver versions, feature support matrix, etc.).
+2. **Local dev cut**: just run the script normally. `generate:smart` will regenerate `databases.json` using your local Flask environment — accurate to whatever drivers/extras you have installed, but typically less complete than the CI artifact.
+3. **No Flask available**: also fine — the database generator falls back to AST parsing of engine spec files. The MDX pages are still correct; only the diagnostics JSON is leaner.
+
+Also: confirm `master` CI is green, and that your local checkout matches the SHA you intend to cut from.
+
 #### Using Automated Scripts (Required)
 
-**⚠️ Important:** Always use these custom commands instead of the native Docusaurus commands. These scripts ensure that both the Docusaurus versioning system AND the `versions-config.json` file are updated correctly.

 ```
 
+What the script does:
+1. Refreshes auto-generated content via `generate:smart` (database pages, API reference, component pages).
+2. Calls `yarn docusaurus docs:version` (or the per-section equivalent) to snapshot the section.
+3. Freezes any data-file imports (`@site/static/*.json`, `../../data/*.json`) into a snapshot-local `_versioned_data/` dir so the historical version doesn't silently mutate when the source files change.
+4. Adjusts relative import paths (`../../src/...` → `../../../src/...`) for files now one directory deeper.
+5. Updates `versions-config.json` and `<section>_versions.json`.
+
 **Do NOT use** the native Docusaurus commands directly (`yarn docusaurus docs:version`), as they will:
 - ❌ Create version files but NOT update `versions-config.json`
+- ❌ Skip auto-gen refresh, freezing whatever was on disk
+- ❌ Skip data-import freezing, leaving the snapshot pointed at live data
 - ❌ Cause versions to not appear in dropdown menus

+# Alerts and Reports
+
+Users can configure automated alerts and reports to send dashboards or charts to an email recipient or Slack channel.
+
+- *Alerts* are sent when a SQL condition is reached
+- *Reports* are sent on a schedule
+
+Alerts and reports are disabled by default. To turn them on, you'll need to change configuration settings and install a suitable headless browser in your environment.
+
+## Requirements
+
+### Commons
+
+#### In your `superset_config.py` or `superset_config_docker.py`
+
+- `"ALERT_REPORTS"` [feature flag](/admin-docs/configuration/configuring-superset#feature-flags) must be turned to True.
+- `beat_schedule` in CeleryConfig must contain schedule for `reports.scheduler`.
+- At least one of those must be configured, depending on what you want to use:
+  - emails: `SMTP_*` settings
+  - Slack messages: `SLACK_API_TOKEN`
+- Users can customize the email subject by including date code placeholders, which will automatically be replaced with the corresponding UTC date when the email is sent. To enable this functionality, activate the `"DATE_FORMAT_IN_EMAIL_SUBJECT"` [feature flag](/admin-docs/configuration/configuring-superset#feature-flags). This enables date formatting in email subjects, preventing all reporting emails from being grouped into the same thread (optional for the reporting feature).
+    - Use date codes from [strftime.org](https://strftime.org/) to create the email subject.
+    - If no date code is provided, the original string will be used as the email subject.
+
+##### Disable dry-run mode
+
+Screenshots will be taken but no messages actually sent as long as `ALERT_REPORTS_NOTIFICATION_DRY_RUN = True`, its default value in `docker/pythonpath_dev/superset_config.py`.  To disable dry-run mode and start receiving email/Slack notifications, set `ALERT_REPORTS_NOTIFICATION_DRY_RUN` to `False` in [superset config](https://github.com/apache/superset/blob/master/docker/pythonpath_dev/superset_config.py).
+
+#### In your `Dockerfile`
+
+You'll need to extend the Superset image to include a headless browser. Your options include:
+- Use Playwright with Chromium: this is the recommended approach as of version 4.1.x or greater. Playwright always uses Chromium — the `WEBDRIVER_TYPE` config setting has no effect when Playwright is active. A working example of a Dockerfile that installs these tools is provided under "Building your own production Docker image" on the [Docker Builds](/admin-docs/installation/docker-builds#building-your-own-production-docker-image) page. Enable the `PLAYWRIGHT_REPORTS_AND_THUMBNAILS` feature flag in your config to activate it.
+- Use Firefox (Selenium): you'll need to install geckodriver and Firefox. Set `WEBDRIVER_TYPE` to `"firefox"` in your `superset_config.py`.
+- Use Chrome (Selenium): you'll need to install Chrome. Set `WEBDRIVER_TYPE` to `"chrome"` in your `superset_config.py`.
+
+In Superset versions <=4.0x, users installed Firefox or Chrome and that was documented here.
+
+Only the worker container needs the browser.
+
+### Slack integration
+
+To send alerts and reports to Slack channels, you need to create a new Slack Application on your workspace.
+
+1. Connect to your Slack workspace, then head to [https://api.slack.com/apps].
+2. Create a new app.
+3. Go to "OAuth & Permissions" section, and give the following scopes to your app:
+   - `incoming-webhook`
+   - `files:write`
+   - `chat:write`
+   - `channels:read`
+   - `groups:read`
+4. At the top of the "OAuth and Permissions" section, click "install to workspace".
+5. Select a default channel for your app and continue.
+   (You can post to any channel by inviting your Superset app into that channel).
+6. The app should now be installed in your workspace, and a "Bot User OAuth Access Token" should have been created. Copy that token in the `SLACK_API_TOKEN` variable of your `superset_config.py`.
+7. Ensure the feature flag `ALERT_REPORT_SLACK_V2` is set to True in `superset_config.py`
+8. Restart the service (or run `superset init`) to pull in the new configuration.
+
+Note: when you configure an alert or a report, the Slack channel list takes channel names without the leading '#' e.g. use `alerts` instead of `#alerts`.
+
+#### Large Slack Workspaces (10k+ channels)
+
+For workspaces with many channels, fetching the complete channel list can take several minutes and may encounter Slack API rate limits. Add the following to your `superset_config.py`:
+
+```python
+from datetime import timedelta
+
+# Increase cache timeout to reduce API calls
+# Default: 1 day (86400 seconds)
+SLACK_CACHE_TIMEOUT = int(timedelta(days=2).total_seconds())
+
+# Increase retry count for rate limit errors
+# Default: 2
+SLACK_API_RATE_LIMIT_RETRY_COUNT = 5
+```
+
+#### Slack Enterprise Grid (org-scoped tokens)
+
+On a Slack Enterprise Grid org, an org-scoped token spans multiple workspaces, so
+workspace-scoped methods such as `conversations.list` require a `team_id` to
+indicate which workspace to target. Set `SLACK_TEAM_ID` to your workspace (team)
+ID so Superset can list channels and deliver reports:
+
+```python
+# The workspace (team) ID to target, e.g. "T01234567"
+SLACK_TEAM_ID = "T01234567"
+```
+
+This defaults to `None` and only needs to be set when using an org-scoped token;
+it is accepted but ignored for standard workspace-level tokens.
+
+### Webhook integration
+
+Superset can send alert and report notifications to any HTTP endpoint — useful for chat platforms, incident management tools, or custom automation.
+
+#### Enabling Webhooks
+
+Enable the feature flag in `superset_config.py`:
+
+```python
+FEATURE_FLAGS = {
+    "ALERT_REPORTS": True,
+    "ALERT_REPORT_WEBHOOK": True,
+}
+```
+
+#### Configuring a Webhook Recipient
+
+When creating or editing an alert or report, select **Webhook** as the notification method and enter your endpoint URL.
+
+#### Payload Format
+
+Superset sends an HTTP POST with `Content-Type: application/json`:
+
+```json
+{
+  "name": "My Alert",
+  "header": {
+    "notification_format": "JSON",
+    "notification_type": "Alert",
+    "notification_source": "Alert",
+    "chart_id": 42,
+    "dashboard_id": null
+  },
+  "text": "Alert condition met: value exceeded threshold",
+  "description": "Monthly revenue dropped below target",
+  "url": "https://your-superset-host/superset/dashboard/1/"
+}
+```
+
+When a report includes file attachments (CSV, Excel, PDF, or PNG screenshots), the request is sent as `multipart/form-data` instead. In that case, each top-level payload field (`name`, `text`, `description`, `url`) becomes its own form field, and nested structures like `header` are serialized as a JSON-encoded string in their own field. Every attachment is added as a repeated form field named `files`:
+
+```
+POST /webhook HTTP/1.1
+Content-Type: multipart/form-data; boundary=...
+
+--...
+Content-Disposition: form-data; name="name"
+
+My Alert
+--...
+Content-Disposition: form-data; name="header"
+
+{"notification_format": "JSON", "notification_type": "Alert", ...}
+--...
+Content-Disposition: form-data; name="text"
+
+Alert condition met: value exceeded threshold
+--...
+Content-Disposition: form-data; name="files"; filename="report.csv"
+Content-Type: text/csv
+
+<file bytes>
+--...
+```
+
+Webhook consumers should branch on `Content-Type`: parse the body as JSON when `application/json`, or read the individual form fields (decoding `header` as JSON) when `multipart/form-data`.
+
+#### HTTPS Enforcement
+
+To require HTTPS webhook URLs (recommended for production), set:
+
+```python
+ALERT_REPORTS_WEBHOOK_HTTPS_ONLY = True
+```
+
+When enabled, Superset rejects webhook configurations that use `http://` URLs.
+
+#### Retry Behavior
+
+Superset automatically retries webhook deliveries on `429 Too Many Requests` and `5xx` server errors using exponential backoff. Retries are bounded to roughly 120 seconds of cumulative wall-clock time (worst case ~210 seconds, because the bound is checked against the time elapsed before each attempt, so the final request can begin just under the limit and still run its full request timeout), after which the delivery is abandoned.
+
+### Kubernetes-specific
+
+- You must have a `celery beat` pod running. If you're using the chart included in the GitHub repository under [helm/superset](https://github.com/apache/superset/tree/master/helm/superset), you need to put `supersetCeleryBeat.enabled = true` in your values override.
+- You can see the dedicated docs about [Kubernetes installation](/admin-docs/installation/kubernetes) for more details.
+
+### Docker Compose specific
+
+#### You must have in your `docker-compose.yml`
+
+- A Redis message broker
+- PostgreSQL DB instead of SQLlite
+- One or more `celery worker`
+- A single `celery beat`
+
+This process also works in a Docker swarm environment, you would just need to add `Deploy:` to the Superset, Redis and Postgres services along with your specific configs for your swarm.
+
+### Detailed config
+
+The following configurations need to be added to the `superset_config.py` file. This file is loaded when the image runs, and any configurations in it will override the default configurations found in the `config.py`.
+
+You can find documentation about each field in the default `config.py` in the GitHub repository under [superset/config.py](https://github.com/apache/superset/blob/master/superset/config.py).
+
+You need to replace default values with your custom Redis, Slack and/or SMTP config.
+
+Superset uses Celery beat and Celery worker(s) to send alerts and reports.
+
+- The beat is the scheduler that tells the worker when to perform its tasks. This schedule is defined when you create the alert or report.
+- The worker will process the  tasks that need to be performed when an alert or report is fired.
+
+In the `CeleryConfig`, only the `beat_schedule` is relevant to this feature, the rest of the `CeleryConfig` can be changed for your needs.
+
+```python
+from celery.schedules import crontab
+
+FEATURE_FLAGS = {
+    "ALERT_REPORTS": True
+}
+
+REDIS_HOST = "superset_cache"
+REDIS_PORT = "6379"
+
+class CeleryConfig:
+    broker_url = f"redis://{REDIS_HOST}:{REDIS_PORT}/0"
+    imports = (
+        "superset.sql_lab",
+        "superset.tasks.scheduler",
+    )
+    result_backend = f"redis://{REDIS_HOST}:{REDIS_PORT}/0"
+    worker_prefetch_multiplier = 10
+    task_acks_late = True
+    task_annotations = {
+        "sql_lab.get_sql_results": {
+            "rate_limit": "100/s",
+        },
+    }
+    beat_schedule = {
+        "reports.scheduler": {
+            "task": "reports.scheduler",
+            "schedule": crontab(minute="*", hour="*"),
+        },
+        "reports.prune_log": {
+            "task": "reports.prune_log",
+            "schedule": crontab(minute=0, hour=0),
+        },
+    }
+CELERY_CONFIG = CeleryConfig
+
+SCREENSHOT_LOCATE_WAIT = 100
+SCREENSHOT_LOAD_WAIT = 600
+
+# Slack configuration
+SLACK_API_TOKEN = "xoxb-"
+
+# Email configuration
+SMTP_HOST = "smtp.sendgrid.net" # change to your host
+SMTP_PORT = 2525 # your port, e.g. 587
+SMTP_STARTTLS = True
+SMTP_SSL_SERVER_AUTH = True # If you're using an SMTP server with a valid certificate
+SMTP_SSL = False
+SMTP_USER = "your_user" # use the empty string "" if using an unauthenticated SMTP server
+SMTP_PASSWORD = "your_password" # use the empty string "" if using an unauthenticated SMTP server
+SMTP_MAIL_FROM = "noreply@youremail.com"
+EMAIL_REPORTS_SUBJECT_PREFIX = "[Superset] " # optional - overwrites default value in config.py of "[Report] "
+
+# WebDriver configuration
+# If you use Firefox or Playwright with Chrome, you can stick with default values
+# If you use Chrome and are *not* using Playwright, then add the following WEBDRIVER_TYPE and WEBDRIVER_OPTION_ARGS
+WEBDRIVER_TYPE = "chrome"
+WEBDRIVER_OPTION_ARGS = [
+    "--force-device-scale-factor=2.0",
+    "--high-dpi-support=2.0",
+    "--headless",
+    "--disable-gpu",
+    "--disable-dev-shm-usage",
+    "--no-sandbox",
+    "--disable-setuid-sandbox",
+    "--disable-extensions",
+]
+
+# This is for internal use, you can keep http
+WEBDRIVER_BASEURL = "http://superset:8088" # When running using docker compose use "http://superset_app:8088'
+# This is the link sent to the recipient. Change to your domain, e.g. https://superset.mydomain.com
+WEBDRIVER_BASEURL_USER_FRIENDLY = "http://localhost:8088"
+```
+
+You also need
+to specify on behalf of which username to render the dashboards. In general, dashboards and charts
+are not accessible to unauthorized requests, that is why the worker needs to take over credentials
+of an existing user to take a snapshot.
+
+By default, Alerts and Reports are executed as a physical user represented by the alert/report editors
+(giving priority to the last modifier, then the creator, then the first direct user editor, then a
+deterministic user from editor roles or groups). To use a fixed user account, just change the config
+as follows (`admin` in this example):
+
+```python
+from superset.tasks.types import FixedExecutor
+
+ALERT_REPORTS_EXECUTORS = [FixedExecutor("admin")]
+```
+
+Please refer to `ExecutorType` in the codebase for other executor types.
+
+**Important notes**
+
+- Be mindful of the concurrency setting for celery (using `-c 4`). Selenium/webdriver instances can
+  consume a lot of CPU / memory on your servers.
+- In some cases, if you notice a lot of leaked geckodriver processes, try running your celery
+  processes with `celery worker --pool=prefork --max-tasks-per-child=128 ...`
+- It is recommended to run separate workers for the `sql_lab` and `email_reports` tasks. This can be
+  done using the `queue` field in `task_annotations`.
+- Adjust `WEBDRIVER_BASEURL` in your configuration file if celery workers can’t access Superset via
+  its default value of `http://0.0.0.0:8080/`.
+
+It's also possible to specify a minimum interval between each report's execution through the config file:
+
+``` python
+# Set a minimum interval threshold between executions (for each Alert/Report)
+# Value should be an integer
+ALERT_MINIMUM_INTERVAL = int(timedelta(minutes=10).total_seconds())
+REPORT_MINIMUM_INTERVAL = int(timedelta(minutes=5).total_seconds())
+```
+
+Alternatively, you can assign a function to `ALERT_MINIMUM_INTERVAL` and/or `REPORT_MINIMUM_INTERVAL`. This is useful to dynamically retrieve a value as needed:
+
+``` python
+def alert_dynamic_minimal_interval(**kwargs) -> int:
+    """
+    Define logic here to retrieve the value dynamically
+    """
+
+ALERT_MINIMUM_INTERVAL = alert_dynamic_minimal_interval
+```
+
+## External Link Redirection
+
+For security, Superset rewrites external links in alert/report email HTML so
+they go through a warning page before the user is navigated to the external
+site.  Internal links (matching your configured base URL) are not affected.
+
+```python
+# Disable external link redirection entirely (default: True)
+ALERT_REPORTS_ENABLE_LINK_REDIRECT = False
+```
+
+The feature uses `WEBDRIVER_BASEURL_USER_FRIENDLY` (or `WEBDRIVER_BASEURL`)
+to determine which hosts are internal.
+
+## Troubleshooting
+
+There are many reasons that reports might not be working.  Try these steps to check for specific issues.
+
+### Confirm feature flag is enabled and you have sufficient permissions
+
+If you don't see "Alerts & Reports" under the *Manage* section of the Settings dropdown in the Superset UI, you need to enable the `ALERT_REPORTS` feature flag (see above). Enable another feature flag and check to see that it took effect, to verify that your config file is getting loaded.
+
+Log in as an admin user to ensure you have adequate permissions.
+
+### Check the logs of your Celery worker
+
+This is the best source of information about the problem.  In a docker compose deployment, you can do this with a command like `docker logs superset_worker --since 1h`.
+
+### Check web browser and webdriver installation
+
+To take a screenshot, the worker visits the dashboard or chart using a headless browser, then takes a screenshot. If you are able to send a chart as CSV, XLSX, or text but can't send as PNG, your problem may lie with the browser.
+
+If you are handling the installation of the headless browser on your own, do your own verification to ensure that the headless browser opens successfully in the worker environment.
+
+### Send a test email
+
+One symptom of an invalid connection to an email server is receiving an error of `[Errno 110] Connection timed out` in your logs when the report tries to send.
+
+Confirm via testing that your outbound email configuration is correct.  Here is the simplest test, for an un-authenticated email SMTP email service running on port 25.  If you are sending over SSL, for instance, study how [Superset's codebase sends emails](https://github.com/apache/superset/blob/master/superset/utils/core.py#L818) and then test with those commands and arguments.
+
+Start Python in your worker environment, replace all example values, and run:
+
+```python
+import smtplib
+from email.mime.multipart import MIMEMultipart
+from email.mime.text import MIMEText
+
+from_email = 'superset_emails@example.com'
+to_email = 'your_email@example.com'
+msg = MIMEMultipart()
+msg['From'] = from_email
+msg['To'] = to_email
+msg['Subject'] = 'Superset SMTP config test'
+message = 'It worked'
+msg.attach(MIMEText(message))
+mailserver = smtplib.SMTP('smtpmail.example.com', 25)
+mailserver.sendmail(from_email, to_email, msg.as_string())
+mailserver.quit()
+```
+
+This should send an email.
+
+Possible fixes:
+
+- Some cloud hosts disable outgoing unauthenticated SMTP email to prevent spam.  For instance, [Azure blocks port 25 by default on some machines](https://learn.microsoft.com/en-us/azure/virtual-network/troubleshoot-outbound-smtp-connectivity). Enable that port or use another sending method.
+- Use another set of SMTP credentials that you verify works in this setup.
+
+### Browse to your report from the worker
+
+The worker may be unable to reach the report. It will use the value of `WEBDRIVER_BASEURL` to browse to the report.  If that route is invalid, or presents an authentication challenge that the worker can't pass, the report screenshot will fail.
+
+Check this by attempting to `curl` the URL of a report that you see in the error logs of your worker. For instance, from the worker environment, run `curl http://superset_app:8088/superset/dashboard/1/`. You may get different responses depending on whether the dashboard exists - for example, you may need to change the `1` in that URL. If there's a URL in your logs from a failed report screenshot, that's a good place to start. The goal is to determine a valid value for `WEBDRIVER_BASEURL` and determine if an issue like HTTPS or authentication is redirecting your worker.
+
+In a deployment with authentication measures enabled like HTTPS and Single Sign-On, it may make sense to have the worker navigate directly to the Superset application running in the same location, avoiding the need to sign in.  For instance, you could use `WEBDRIVER_BASEURL="http://superset_app:8088"` for a docker compose deployment, and set `"force_https": False,` in your `TALISMAN_CONFIG`.
+
+### Duplicate report deliveries
+
+In some deployment configurations a scheduled report can be delivered more than once around its planned time. This typically happens when more than one process is responsible for running the alerts & reports schedule (for example, multiple schedulers or Celery beat instances). To avoid duplicate emails or notifications:
+
+- Ensure that only a **single scheduler/beat process** is configured to trigger alerts and reports for a given environment.
+- If you run **multiple Celery workers**, verify that there is still only one component responsible for scheduling the report tasks (workers should execute tasks, not schedule them independently).
+- Review your deployment/orchestration setup (for example systemd, Docker, or Kubernetes) to make sure the alerts & reports scheduler is **not started from multiple places by accident**.
+
+## Scheduling Queries as Reports
+
+You can optionally allow your users to schedule queries directly in SQL Lab. This is done by adding
+extra metadata to saved queries, which are then picked up by an external scheduled (like
+[Apache Airflow](https://airflow.apache.org/)).
+
+To allow scheduled queries, add the following to `SCHEDULED_QUERIES` in your configuration file:
+
+```python
+SCHEDULED_QUERIES = {
+    # This information is collected when the user clicks "Schedule query",
+    # and saved into the `extra` field of saved queries.
+    # See: https://github.com/mozilla-services/react-jsonschema-form
+    'JSONSCHEMA': {
+        'title': 'Schedule',

+            'In order to schedule a query, you need to specify when it '
+            'should start running, when it should stop running, and how '
+            'often it should run. You can also optionally specify '
+            'dependencies that should be met before the query is '
+            'executed. Please read the documentation for best practices '
+            'and more information on how to specify dependencies.'

+            },
+            'end_date': {
+                'type': 'string',
+                'title': 'End date',
+                # date-time is parsed using the chrono library, see

+                'type': 'string',

+            'ui:placeholder': '@daily, @weekly, etc.',
+        },
+        'dependencies': {
+            'ui:help': (
+                'Check the documentation for the correct format when '
+                'defining dependencies.'
+            ),
+        },
+    },
+    'VALIDATION': [
+        # ensure that start_date <= end_date
+        {
+            'name': 'less_equal',
+            'arguments': ['start_date', 'end_date'],
+            'message': 'End date cannot be before start date',
+            # this is where the error message is shown
+            'container': 'end_date',
+        },
+    ],
+    # link to the scheduler; this example links to an Airflow pipeline
+    # that uses the query id and the output table as its name
+    'linkback': (
+        'https://airflow.example.com/admin/airflow/tree?'
+        'dag_id=query_${id}_${extra_json.schedule_info.output_table}'
+    ),
+}
+```
+
+This configuration is based on
+[react-jsonschema-form](https://github.com/mozilla-services/react-jsonschema-form) and will add a
+menu item called “Schedule” to SQL Lab. When the menu item is clicked, a modal will show up where
+the user can add the metadata required for scheduling the query.
+
+This information can then be retrieved from the endpoint `/api/v1/saved_query/` and used to
+schedule the queries that have `schedule_info` in their JSON metadata. For schedulers other than
+Airflow, additional fields can be easily added to the configuration file above.

+# AWS IAM Authentication for AWS Databases
+
+Superset supports IAM-based authentication for **Amazon Aurora** (PostgreSQL and MySQL) and **Amazon Redshift**. IAM auth eliminates the need for database passwords — Superset generates a short-lived auth token using temporary AWS credentials instead.
+
+Cross-account IAM role assumption via STS `AssumeRole` is supported, allowing a Superset deployment in one AWS account to connect to databases in a different account.
+
+## Prerequisites
+
+- Enable the `AWS_DATABASE_IAM_AUTH` feature flag in `superset_config.py`. IAM authentication is gated behind this flag; if it is disabled, connections using `aws_iam` fail with *"AWS IAM database authentication is not enabled."*
+  ```python
+  FEATURE_FLAGS = {
+      "AWS_DATABASE_IAM_AUTH": True,
+  }
+  ```
+- `boto3` must be installed in your Superset environment:
+  ```bash
+  pip install boto3
+  ```
+- The Superset server's IAM role (or static credentials) must have permission to call `sts:AssumeRole` (for cross-account) or the same-account permissions for the target service:
+  - **Aurora (RDS)**: `rds-db:connect`
+  - **Redshift provisioned**: `redshift:GetClusterCredentials`
+  - **Redshift Serverless**: `redshift-serverless:GetCredentials` and `redshift-serverless:GetWorkgroup`
+- SSL must be enabled on the Aurora / Redshift endpoint (required for IAM token auth).
+
+## Configuration
+
+IAM authentication is configured via the **encrypted_extra** field of the database connection. Access this field in the **Advanced** → **Security** section of the database connection form, under **Secure Extra**.
+
+### Aurora PostgreSQL or Aurora MySQL
+
+```json
+{
+  "aws_iam": {
+    "enabled": true,
+    "role_arn": "arn:aws:iam::222222222222:role/SupersetDatabaseAccess",
+    "external_id": "superset-prod-12345",
+    "region": "us-east-1",
+    "db_username": "superset_iam_user",
+    "session_duration": 3600
+  }
+}
+```
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `enabled` | Yes | Set to `true` to activate IAM auth |
+| `role_arn` | No | ARN of the cross-account IAM role to assume via STS. Omit for same-account auth |
+| `external_id` | No | External ID for the STS `AssumeRole` call, if required by the target role's trust policy |
+| `region` | Yes | AWS region of the database cluster |
+| `db_username` | Yes | The database username associated with the IAM identity |
+| `session_duration` | No | STS session duration in seconds (default: `3600`) |
+
+### Redshift (Serverless)
+
+```json
+{
+  "aws_iam": {
+    "enabled": true,
+    "role_arn": "arn:aws:iam::222222222222:role/SupersetRedshiftAccess",
+    "region": "us-east-1",
+    "workgroup_name": "my-workgroup",
+    "db_name": "dev"
+  }
+}
+```
+
+### Redshift (Provisioned Cluster)
+
+```json
+{
+  "aws_iam": {
+    "enabled": true,
+    "role_arn": "arn:aws:iam::222222222222:role/SupersetRedshiftAccess",
+    "region": "us-east-1",
+    "cluster_identifier": "my-cluster",
+    "db_username": "superset_iam_user",
+    "db_name": "dev"
+  }
+}
+```
+
+## Cross-Account IAM Setup
+
+To connect to a database in Account B from a Superset deployment in Account A:
+
+**1. In Account B — create a database-access role:**
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": ["rds-db:connect"],
+      "Resource": "arn:aws:rds-db:us-east-1:222222222222:dbuser/db-XXXXXXXXXXXX/superset_iam_user"
+    }
+  ]
+}
+```
+
+**Trust policy** (allows Account A's Superset role to assume it):
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Principal": {
+        "AWS": "arn:aws:iam::111111111111:role/SupersetInstanceRole"
+      },
+      "Action": "sts:AssumeRole",
+      "Condition": {
+        "StringEquals": {
+          "sts:ExternalId": "superset-prod-12345"
+        }
+      }
+    }
+  ]
+}
+```
+
+**2. In Account A — grant Superset's role permission to assume the Account B role:**
+
+```json
+{

+
+## Credential Caching
