+### 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.

+- [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.

+### 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.

+### 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.

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

+### 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`.

+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.

 **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.

Because Module Federation caches the resolved module per container, every import of `@apache-superset/core` inside that extension resolves to this pre-bound copy for the lifetime of the container, and because each container gets its own independent scope object, extensions loading in parallel cannot see each other's context.
+4. **Execution**: The extension code runs with access to the host's APIs (via its per-extension `@apache-superset/core` instance) and shared dependencies (`react`, `react-dom`, `antd`)

 ### Host API Setup

-On the Superset side, the APIs are mapped to `window.superset` during application bootstrap:
+On the Superset side, the real implementations backing `@apache-superset/core` (`commands`, `views`, `menus`, `extensions`, etc.) are assigned onto `window.superset` during application bootstrap, once the current user is known:

 ```typescript
+// eslint-disable-next-line no-restricted-syntax
 import * as supersetCore from '@apache-superset/core';
+import { commands, views, menus, extensions /* ... */ } from 'src/core';

-export default function setupExtensionsAPI() {
-  window.superset = {
-    ...supersetCore,
-  };
-}
+window.superset = {
+  ...supersetCore,
+  commands,
+  views,
+  menus,
+  extensions,
+  // ...
+};
 ```

-This function runs before any extensions are loaded, ensuring the APIs are available when extensions import from `@apache-superset/core`.
+This runs before any extensions are loaded. `window.superset` is not itself what an extension's `@apache-superset/core` import resolves to — it is the source object the loader reads from when building each extension's per-container scoped instance (see [Runtime Resolution](#runtime-resolution)), so every extension ends up sharing the same underlying `commands`/`views`/`menus` singletons but with its own `extensions.getContext()`.

+The webpack configuration requires specific settings for Module Federation. `@apache-superset/core` is declared as a `shared` singleton alongside `react`/`react-dom`/`antd` — Superset injects a per-extension instance of the package into the container's share scope at load time, so the extension's own webpack config only needs to mark it `shared` with `singleton: true`, not resolve it itself. `import: false` on each shared entry means the extension doesn't bundle its own copy and instead uses the instance the host (or, for `@apache-superset/core`, the loader) provides. `remoteEntry.[contenthash].js` gives the built remote entry file a content hash for cache busting.

 **Convention**: Superset always loads extensions by requesting the `./index` module from the Module Federation container. The `exposes` entry must be exactly `'./index': './src/index.tsx'` — do not rename or add additional entries. All API registrations must be reachable from that file. See [Architecture](./architecture.md#module-federation) for a full explanation.

+
+# Storage
+
+Superset Extensions have access to a managed storage API for persisting data. The storage system provides multiple tiers with different persistence characteristics, allowing extensions to choose the right storage for their needs.
+
+Each extension receives its own isolated storage namespace. When Superset loads your extension, it binds storage to your extension's unique identifier, ensuring data privacy—two extensions using the same key will never collide, and extensions cannot access each other's data.
+
+Storage is always accessed through the extension context via `getContext()`. This binding to the context is what ties every operation to the current extension's namespace.
+
+## Storage Tiers
+
+| Tier | Storage Type      | Context Property                           | Use Case                               |
+| ---- | ----------------- | ------------------------------------------ | -------------------------------------- |
+| 1    | Browser storage   | `ctx.storage.local`, `ctx.storage.session` | UI state, wizard progress, draft forms |
+| 2    | Server-side cache | `ctx.storage.ephemeral`                    | Job progress, temporary results        |
+| 3    | Database          | `ctx.storage.persistent`                   | Saved artifacts, durable config        |
+
+## Tier 1: Local State
+
+Browser-based storage that persists on the user's device. Use this for UI state and settings that don't need to sync across devices.
+
+### Why Use the API Instead of localStorage Directly?
+
+You might wonder why extensions should use `ctx.storage.local` instead of directly accessing `window.localStorage`. The managed API provides several benefits:
+
+- **Automatic namespacing**: Each extension's data is isolated. Two extensions using the same key name won't collide.
+- **User isolation**: By default, data is scoped to the current user, preventing data leakage between users on shared devices.
+- **Clean uninstall**: When an extension is uninstalled, all its data can be cleanly removed using prefix-based deletion.
+- **Future sandboxing**: The async API is designed for a future sandboxed execution model where extensions run in isolated contexts without direct DOM access.
+- **Consistent patterns**: The same API shape works across all storage tiers, making it easy to switch between them.
+
+### localState
+
+Data persists across browser sessions until explicitly deleted or the user clears browser storage.
+
+```typescript
+import { extensions } from '@apache-superset/core';
+
+const ctx = extensions.getContext();
+
+// Save sidebar state
+await ctx.storage.local.set('sidebar_collapsed', true);
+
+// Retrieve it later
+const isCollapsed = await ctx.storage.local.get('sidebar_collapsed');
+
+// Remove it
+await ctx.storage.local.remove('sidebar_collapsed');
+```
+
+### sessionState
+
+Data is cleared when the browser tab is closed. Use for transient state within a single session.
+
+```typescript
+import { extensions } from '@apache-superset/core';
+
+const ctx = extensions.getContext();
+
+// Save wizard progress (lost when tab closes)
+await ctx.storage.session.set('wizard_step', 3);
+await ctx.storage.session.set('unsaved_form', { name: 'Draft' });
+
+// Retrieve on page reload within same tab
+const step = await ctx.storage.session.get('wizard_step');
+```
+
+Tier 1 has no `shared` accessor. Browser storage is per-device, so a "shared" value would only be visible to other users of that same browser, not to other users of the extension generally — see `.shared` on [Tier 2](#tier-2-ephemeral-state) or [Tier 3](#tier-3-persistent-state) for storage that's actually shared across users.
+
+### When to Use Tier 1
+
+- UI state (sidebar collapsed, panel sizes)
+- Recently used items
+- Draft form values
+- Any data acceptable to lose if user clears browser
+
+### Limitations
+
+- Per-browser, per-device (not shared across devices)
+- Subject to browser storage quotas (~5-10 MB)
+- Not accessible from backend code
+
+## Tier 2: Ephemeral State
+
+Server-side cache storage with automatic TTL expiration. Use for temporary data that needs to be shared between frontend and backend, or persist across page reloads.
+
+TTL is required for every `set` call. The maximum allowed TTL is controlled by `MAX_TTL` in the server configuration.
+
+### Frontend Usage
+
+```typescript
+import { extensions } from '@apache-superset/core';
+
+const ctx = extensions.getContext();
+
+// Store with a 5-minute TTL
+await ctx.storage.ephemeral.set('job_progress', { pct: 42, status: 'running' }, { ttl: 300 });
+
+// Retrieve
+const progress = await ctx.storage.ephemeral.get('job_progress');
+
+// Remove
+await ctx.storage.ephemeral.remove('job_progress');
+```
+
+### Backend Usage
+
+```python
+from superset_core.extensions.context import get_context
+from superset_core.extensions.storage.ephemeral import EphemeralSetOptions
+
+ctx = get_context()
+
+# Store job progress with a 5-minute TTL
+ctx.storage.ephemeral.set(
+    'job_progress', {'pct': 42, 'status': 'running'}, EphemeralSetOptions(ttl=300)
+)
+
+# Retrieve
+progress = ctx.storage.ephemeral.get('job_progress')
+
+# Remove
+ctx.storage.ephemeral.remove('job_progress')
+```
+
+### Shared State
+
+For data that needs to be visible to all users:
+
+```typescript
+import { extensions } from '@apache-superset/core';
+
+const ctx = extensions.getContext();
+
+await ctx.storage.ephemeral.shared.set('shared_result', { data: [1, 2, 3] }, { ttl: 3600 });
+const result = await ctx.storage.ephemeral.shared.get('shared_result');
+```
+
+```python
+from superset_core.extensions.context import get_context
+from superset_core.extensions.storage.ephemeral import EphemeralSetOptions
+
+ctx = get_context()
+
+ctx.storage.ephemeral.shared.set(
+    'shared_result', {'data': [1, 2, 3]}, EphemeralSetOptions(ttl=3600)
+)
+result = ctx.storage.ephemeral.shared.get('shared_result')
+```
+
+### When to Use Tier 2
+
+- Background job progress indicators
+- Cross-request intermediate state
+- Query result previews
+- Temporary computation results
+- Any data that can be recomputed if lost
+
+### Limitations
+
+- Not guaranteed to survive server restarts
+- Subject to cache eviction under memory pressure
+- TTL-based expiration (data disappears after timeout)
+- TTL is required on every `set` call
+
+## Tier 3: Persistent State
+
+Database-backed storage that survives server restarts, cache evictions, and browser clears. Use for any data that must not be lost.
+
+### Frontend Usage
+
+```typescript
+import { extensions } from '@apache-superset/core';
+
+const ctx = extensions.getContext();
+
+// Store a saved SQL snippet
+await ctx.storage.persistent.set('snippet:top_customers', { sql: 'SELECT ...' });
+
+// Retrieve
+const snippet = await ctx.storage.persistent.get('snippet:top_customers');
+
+// Remove
+await ctx.storage.persistent.remove('snippet:top_customers');
+```
+
+### Backend Usage
+
+```python
+from superset_core.extensions.context import get_context
+
+ctx = get_context()
+
+# Store a saved SQL snippet
+ctx.storage.persistent.set('snippet:top_customers', {'sql': 'SELECT ...'})
+
+# Retrieve
+snippet = ctx.storage.persistent.get('snippet:top_customers')
+
+# Remove
+ctx.storage.persistent.remove('snippet:top_customers')
+```
+
+### Shared State
+
+For data that should be visible to all users of the extension:
+
+```typescript
+import { extensions } from '@apache-superset/core';
+
+const ctx = extensions.getContext();
+
+await ctx.storage.persistent.shared.set('global_config', { version: 2 });
+const config = await ctx.storage.persistent.shared.get('global_config');
+```
+
+```python
+from superset_core.extensions.context import get_context
+
+ctx = get_context()
+
+ctx.storage.persistent.shared.set('global_config', {'version': 2})
+config = ctx.storage.persistent.shared.get('global_config')
+```
+
+### Listing Entries
+
+Both the frontend and backend accessors support listing entries in the caller's scope, without needing to know every key in advance. `page` and `pageSize`/`page_size` are required on every call — `list()` always returns one page of results, never the whole result set, so there's no default that could make that fact easy to miss. Check the returned `count` (total entries matching the scope/filters, across all pages) against `pageSize`/`page_size` to know whether more pages exist.
+
+```typescript
+import { extensions } from '@apache-superset/core';
+
+const ctx = extensions.getContext();
+
+// Filter by resource
+const result = await ctx.storage.persistent.list({
+  resourceType: 'dashboard',
+  resourceUuid: '1234-uuid',
+  page: 0,
+  pageSize: 25,
+});
+result.entries.forEach(entry => {
+  console.log(entry.key, entry.value, entry.codec);
+});
+console.log(result.count); // total matching entries across all pages
+
+// Shared (global) scope
+const shared = await ctx.storage.persistent.shared.list({ page: 0, pageSize: 10 });
+```
+
+```python
+from superset_core.extensions.context import get_context
+from superset_core.extensions.storage.persistent import PersistentListOptions
+
+ctx = get_context()
+
+# Filter by resource
+result = ctx.storage.persistent.list(
+    PersistentListOptions(
+        resource_type="dashboard",
+        resource_uuid="1234-uuid",
+        page=0,
+        page_size=25,
+    )
+)
+for entry in result.entries:
+    print(entry.key, entry.value, entry.codec)
+print(result.count)  # total matching entries across all pages
+
+# Shared (global) scope
+shared = ctx.storage.persistent.shared.list(PersistentListOptions(page=0, page_size=10))
+```
+
+`resource_type`/`resource_uuid` filter to entries linked to one resource — since a single resource can have several keyed entries (e.g. `"layout"`, `"notes"`), this is how an extension enumerates all of them without tracking key names itself.
+
+There is no fixed limit on `page_size`, but the combined size of a requested page's values is checked against `MAX_LIST_PAYLOAD_SIZE` (see [Quotas](#quotas)) before any row's value is read from the database — a page that would exceed it is rejected rather than silently truncated, so reduce `page_size` and retry if that happens.
+
+Backend `list()` decodes every entry's value unconditionally. The REST API backing the frontend's `list()` call is more restrictive: an entry written with a codec that isn't safe to decode over the wire (e.g. `pickle`) comes back with `value: null` (its `codec` is still reported) rather than being decoded.
+
+### Enumerating and Managing Storage from the Backend
+
+`ctx.storage.persistent.list()` covers the common case of listing an extension's own entries. Backend extension code that needs lower-level bulk operations — for example, a cleanup routine that removes storage linked to resources that no longer exist, using filters `list()` doesn't expose — can use `superset_core.extensions.storage.dao.ExtensionStorageDAO` instead:
+
+```python
+from superset_core.extensions.storage.dao import ExtensionStorageDAO
+
+# All entries this extension has linked to a given resource type
+entries = ExtensionStorageDAO.filter_by(resource_type="my-resource-type")
+
+# Bulk-delete rows for resources that no longer exist
+orphaned = [e for e in entries if e.resource_uuid not in my_extension_live_resource_ids()]
+ExtensionStorageDAO.delete(orphaned)
+```
+
+`ExtensionStorageDAO` is automatically scoped to the calling extension's own rows — `extension_id` is never a parameter you pass, so there is no way to reach another extension's storage through this API. It supports the standard DAO operations `find_all`, `find_one_or_none`, `filter_by`, `query`, `update`, and `delete`. `create()` is not supported — it's a raw insert with no upsert dedup, quota check, or locking against the key `.set()` writes to, so use `ctx.storage.persistent.set()` to write a value instead.
+
+### When to Use Tier 3
+
+- Extension configuration that must survive restarts
+- User-specific saved artifacts that need to roam across devices and browsers (e.g. saved SQL snippets, annotations)
+- Any data where loss is unacceptable
+
+### Limitations
+
+- Higher latency than Tiers 1–2 (database round-trip per operation)
+- Subject to the per-value size limit configured via `EXTENSIONS_PERSISTENT_STORAGE.MAX_VALUE_SIZE` (see [Quotas](#quotas))
+- Subject to the per-extension quota configured via `EXTENSIONS_PERSISTENT_STORAGE.QUOTA_PER_EXTENSION` (see [Quotas](#quotas))
+- Requires a database migration when first deployed
+
+## Working with Binary Data
+
+Tiers 2 and 3 accept a `codec` option describing how `value` is encoded — `"json"` (the default) for JSON-native values, or `"binary"` for raw bytes. `list()` and `get()` report which codec an entry was written with via `entry.codec`.
+
+### Backend
+
+Backend code talks to the storage DAO directly and works with real Python `bytes` — no extra flag is needed:
+
+```python
+from superset_core.extensions.context import get_context
+from superset_core.extensions.storage.persistent import PersistentSetOptions
+
+ctx = get_context()
+
+with open('logo.png', 'rb') as f:
+    png_bytes = f.read()
+
+ctx.storage.persistent.set('logo', png_bytes, PersistentSetOptions(codec='binary'))
+
+stored = ctx.storage.persistent.get('logo')  # raw bytes back, unchanged
+```
+
+### Frontend
+
+The frontend SDK talks to the backend over a JSON REST API, which has no byte type — a binary value must be base64-encoded to travel in a JSON request body. There is no way for the SDK to infer this from a JS value's type, so it is never detected automatically: set `isBinary: true` explicitly whenever `value` is binary.
+
+```typescript
+import { extensions } from '@apache-superset/core';
+
+const ctx = extensions.getContext();
+
+const pngBytes = new Uint8Array([0x89, 0x50, 0x4e, 0x47 /* ... */]);
+await ctx.storage.persistent.set('logo', pngBytes, { isBinary: true });
+```
+
+`get()` returns a binary entry's value exactly as stored on the wire — a base64 string, not a `Uint8Array` — so decode it yourself:
+
+```typescript
+const base64 = await ctx.storage.persistent.get<string>('logo');
+const bytes = Uint8Array.from(atob(base64), c => c.charCodeAt(0));
+```
+
+`list()` entries report `isBinary` alongside `codec`, so you know which entries need decoding before you read `value`:
+
+```typescript
+const result = await ctx.storage.persistent.list({ page: 0, pageSize: 10 });
+result.entries.forEach(entry => {
+  const value = entry.isBinary
+    ? Uint8Array.from(atob(entry.value as string), c => c.charCodeAt(0))
+    : entry.value;
+});
+```
+
+## Key Patterns
+
+All storage keys are automatically namespaced:
+
+| Scope                  | Key Pattern                                        |
+| ---------------------- | -------------------------------------------------- |
+| User-scoped            | `superset-ext:{extension_id}:user:{user_id}:{key}` |
+| Shared (Tiers 2 and 3) | `superset-ext:{extension_id}:shared:{key}`         |
+
+This ensures:
+
+- Extensions cannot accidentally access each other's data
+- Users cannot see other users' data (by default)
+- Clean prefix-based deletion on uninstall
+
+## Configuration
+
+### Tier 2: Ephemeral Storage
+
+Administrators can configure the server-side cache backend in `superset_config.py`:
+
+```python
+EXTENSIONS_EPHEMERAL_STORAGE = {
+    # Use Redis for better performance in production
+    "CACHE_TYPE": "RedisCache",
+    "CACHE_REDIS_URL": "redis://localhost:6379/2",
+    "MAX_TTL": 604800,  # 7 days maximum TTL
+    "MAX_VALUE_SIZE": 100 * 1024,  # 100 KB maximum per stored value
+}
+```
+
+For development, the default `SupersetMetastoreCache` stores data in the metadata database.
+
+### Tier 3: Persistent Storage
+
+Tier 3 values are stored in the `extension_storage` database table. Values are stored unencrypted by default; encryption is opt-in per write, available via a `PersistentSetOptions`-shaped `encrypt` option:
+
+```typescript
+import { extensions } from '@apache-superset/core';
+
+const ctx = extensions.getContext();
+
+await ctx.storage.persistent.set('api_token', 'sk-...', { encrypt: true });
+const token = await ctx.storage.persistent.get('api_token');
+```
+
+```python
+from superset_core.extensions.context import get_context
+from superset_core.extensions.storage.persistent import PersistentSetOptions
+
+ctx = get_context()
+
+ctx.storage.persistent.set('api_token', 'sk-...', PersistentSetOptions(encrypt=True))
+token = ctx.storage.persistent.get('api_token')
+```
+
+Encryption reuses Superset's existing `EncryptedType` (from `sqlalchemy-utils`) rather than a separate mechanism — the same infrastructure used for database connection credentials. The key is not configured directly: user-scoped values are encrypted with a key derived per-user via HMAC-SHA256 from the deployment's `SECRET_KEY`, so ciphertext for one user cannot be decrypted as another's; shared/global values (written via `.shared`) use `SECRET_KEY` directly. The encryption engine (AES-CBC by default) can be changed for the whole deployment via the existing `SQLALCHEMY_ENCRYPTED_FIELD_ENGINE` config, the same setting that controls encryption for database credentials elsewhere in Superset — there is no separate key list or rotation mechanism specific to extension storage. When `SECRET_KEY` is rotated, extension storage rows are re-encrypted by the existing `SecretsMigrator` tooling alongside database credentials, with no extension-specific steps required.
+
+### Quotas
+
+Persistent storage is subject to per-value, per-list-page, and per-extension size limits, configured in `superset_config.py`:
+
+```python
+EXTENSIONS_PERSISTENT_STORAGE = {
+    # Maximum total bytes an extension may store across all of its rows
+    # (global, every user's, and shared). Defaults to 100 MB.
+    "QUOTA_PER_EXTENSION": 100 * 1024 * 1024,
+    # Maximum size (in bytes) of a single stored value. Defaults to 1 MB.
+    "MAX_VALUE_SIZE": 1024 * 1024,
+    # Maximum combined value size (in bytes) that a single list() page may
+    # return. Defaults to 10 MB.
+    "MAX_LIST_PAYLOAD_SIZE": 10 * 1024 * 1024,
+}

+A write that would push the extension's total stored size over `QUOTA_PER_EXTENSION` is rejected — the frontend SDK's `set()` call rejects with an HTTP 413 response, and backend code calling `ctx.storage.persistent.set()` sees the corresponding exception raised. Overwriting an existing key nets out that key's own current size against usage first, so replacing a value with one of the same or smaller size never spuriously fails even when the extension is already near its quota.
+
+A write whose encoded value exceeds `MAX_VALUE_SIZE` is rejected outright, independently of the total quota.
+
+A `list()` call whose requested page would return more than `MAX_LIST_PAYLOAD_SIZE` combined bytes of value data is rejected — reduce `page`/`pageSize` and retry. This check runs against the page's stored sizes before any value is read from the database, so an oversized request fails fast. Because `list()`'s response is consumed as JSON in the browser, raising `MAX_LIST_PAYLOAD_SIZE` substantially above the default risks client-side memory and parse-time issues — treat the default as already generous rather than a floor to build up from.

+# Exporting Dashboard Data to Excel
+
+Superset can export every chart on a dashboard to a single Excel workbook, with
+each chart's underlying data rendered as its own worksheet. The export reflects
+the dashboard's currently applied filters and runs asynchronously: when it
+finishes, the requesting user receives an email with a time-limited download
+link.
+
+## Using the export
+
+From a dashboard, open the **... (actions) → Download** submenu and choose
+**Export Data to Excel**. The action appears for users who have the dashboard
+`can_export` permission. You'll see a confirmation that the export is being
+prepared; the workbook arrives by email when it's ready.
+
+A second option, **Export Images to Excel**, embeds each non-table chart as a
+rendered image (tables stay tabular) instead of exporting raw data. Because it
+renders charts through the headless webdriver, this option only appears when the
+webdriver screenshot feature flags are enabled (see the prerequisites below);
+which viz types stay tabular is controlled by `EXCEL_EXPORT_TABLE_VIZ_TYPES`.
+
+Notes on the generated workbook:
+
+- One worksheet per chart, named `{chart_id} - {chart title}` (truncated to
+  Excel's 31-character limit; the chart id keeps names unique).
+- Charts nested in tabs are included.
+- Data reflects the dashboard's active filter state at the time of export.
+- A chart with no saved query context is skipped and listed in the email; open
+  the chart in Explore and re-save it to include it next time.
+- Row counts per sheet are capped the same way as the chart-level CSV/Excel
+  export (`ROW_LIMIT`, bounded by `SQL_MAX_ROW`), and never exceed Excel's
+  per-sheet maximum.
+
+## Prerequisites
+
+This feature is **disabled by default**. It requires:
+
+1. **The `boto3` dependency.** It is not installed by default; install it with
+   `pip install apache-superset[excel-export]`. Without it, exports fail and the
+   user receives a failure email.
+2. **An S3 bucket.** Set `EXCEL_EXPORT_S3_BUCKET`. Until it is set, the export
+   endpoint returns `501` and the menu action surfaces a "not configured"
+   message.
+3. **A running Celery worker.** The export runs as a Celery task. If no worker
+   is running, the request is accepted but nothing is produced.
+4. **A configured SMTP transport.** The download link is delivered by email
+   using the same settings as alerts & reports (`SMTP_*`,
+   `EMAIL_REPORTS_SUBJECT_PREFIX`).
+
+**Export Images to Excel** additionally requires a working headless webdriver —
+the same infrastructure scheduled reports and thumbnails use (`WEBDRIVER_*`,
+plus the `ENABLE_DASHBOARD_SCREENSHOT_ENDPOINTS` and
+`ENABLE_DASHBOARD_DOWNLOAD_WEBDRIVER_SCREENSHOT` feature flags). The menu option
+is hidden when those flags are off; if the webdriver is unreachable, image
+charts come back empty even though the data export path still works.
+
+Deployments that override `CELERY_CONFIG` must add
+`"superset.tasks.export_dashboard_excel"` to the `imports` tuple, or the task
+will not register.
+
+## Configuration keys
+
+| Key | Default | Description |
+| --- | --- | --- |
+| `EXCEL_EXPORT_S3_BUCKET` | `None` | Destination bucket. Required; `501` if unset. |
+| `EXCEL_EXPORT_S3_KEY_PREFIX` | `"dashboard-exports/"` | Key prefix: `{prefix}{dashboard_id}/{job_id}.xlsx`. |
+| `EXCEL_EXPORT_LINK_TTL_SECONDS` | `86400` | Lifetime of the pre-signed download URL (24h). |
+| `EXCEL_EXPORT_S3_CLIENT_KWARGS` | `{}` | Extra kwargs for `boto3.client("s3", ...)` — e.g. `region_name`, or `endpoint_url` for MinIO/LocalStack. |
+| `EXCEL_EXPORT_TABLE_VIZ_TYPES` | `None` | Viz types kept tabular in **Export Images to Excel** mode; every other type is embedded as an image. `None` uses the built-in default (`table`, `pivot_table`, `pivot_table_v2`). |
+
+Credentials and region resolve through the standard boto3 chain (environment
+variables, shared config, or instance role) unless overridden via
+`EXCEL_EXPORT_S3_CLIENT_KWARGS`. The worker needs `s3:PutObject` on the bucket.
+
+## Security considerations
+
+- The emailed link is a **pre-signed S3 URL**: anyone who holds it can download
+  the workbook until it expires. Keep the bucket **private**, enable
+  encryption, and consider a lifecycle rule to delete objects after a few days.
+  Lower `EXCEL_EXPORT_LINK_TTL_SECONDS` if 24 hours is too long for your data.
+- The export runs with the requesting user's permissions; each chart's query is
+  access-checked, so users only ever receive data they are entitled to.
+
+## Limitations
+
+- **Embedded dashboards / guest tokens are not supported** in this version,
+  because guest users have no email address to deliver the link to. Logged-in
+  users viewing an embedded dashboard can still use the export.
+- The default **Export Data to Excel** mode exports data only (no visual
+  styling). Use **Export Images to Excel** to embed rendered chart images, which
+  requires the webdriver infrastructure described in the prerequisites.
+- Scheduled/automated exports are not part of this feature.

+# Upgrading the Superset Helm Chart
+
+## Upgrading to chart 0.20.0
+
+Chart 0.20.0 introduces a structured connection schema. The old keys listed below are **DEPRECATED** — they still work (auto-mapped to the new keys at render time) and a deprecation warning is printed in `helm install`/`helm upgrade` NOTES, but they will be removed in a future release. Migrate as soon as possible.
+
+### 1. Connection schema: `supersetNode.connections.*` → `database.*` / `cache.*`
+
+**Before (deprecated — still honored):**
+
+```yaml
+supersetNode:
+  connections:
+    db_host: "pg-host"
+    db_port: "5432"
+    db_user: "superset"
+    db_pass: "superset"
+    db_name: "superset"
+    redis_host: "redis-host"
+    redis_port: "6379"
+    redis_cache_db: "1"
+    redis_celery_db: "0"
+    redis_driver: "rediss"
+```
+
+**After (new structured keys — recommended):**
+
+```yaml
+database:
+  host: "pg-host"
+  port: 5432
+  user: "superset"
+  password: "superset"
+  name: "superset"
+
+cache:
+  host: "redis-host"
+  port: 6379
+  cacheDb: 1
+  celeryDb: 0
+  driver: "rediss"   # optional: custom Redis driver / TLS variant
+```
+
+Key-by-key mapping summary:
+
+| Old key | New key |
+|---|---|
+| `supersetNode.connections.db_host` | `database.host` |
+| `supersetNode.connections.db_port` | `database.port` |
+| `supersetNode.connections.db_user` | `database.user` |

+### 2. Service account: root `serviceAccountName` → `serviceAccount.name`
+
+**Before (deprecated — still honored):**
+
+```yaml
+serviceAccountName: my-sa
+```
+
+**After (new key — recommended):**
+
+```yaml
+serviceAccount:
+  name: my-sa
+```
+
+### 3. Init script: `init.initscript` is deprecated and replaced by the built-in template
+
+> **This is a behavior change.** The chart no longer uses `init.initscript`. The init script is rendered
+> entirely from an internal chart template (`superset.initScript`), which runs the full initialization
+> sequence:
+>
+> 1. `superset db upgrade` — applies all pending database schema migrations
+> 2. `superset init` — initializes roles and permissions
+> 3. Admin user creation (when `init.createAdmin: true`)
+> 4. Example data loading (when `init.loadExamples: true`)
+> 5. Datasource import (when `import_datasources.yaml` is present)
+>
+> A future PR will optionally split the database migration step into a dedicated upgrade Job for
+> zero-downtime deployments. Until that PR lands, migrations run as part of the init Job above.
+
+If you customized `init.initscript` in your `values.yaml`, that customization is silently ignored.
+Move any customizations to `config` or `configOverrides`:
+
+```yaml
+# Move custom Python config here:
+config:
+  MY_SETTING: "value"
+
+configOverrides:
+  my_custom_override: |
+    # Python snippet appended to superset_config.py
+    MY_SETTING = "value"
+```
+
+If your use case cannot be covered by `config` or `configOverrides`, please open an issue so the maintainers
+can evaluate extending the template.
+
+### 4. New top-level sections: `config.*` and `featureFlags.*`
+
+Two new sections provide direct Superset configuration passthrough without needing raw `configOverrides`.
+
+**`config.*` — direct Superset config properties:**
+
+```yaml
+config:
+  SECRET_KEY: "$(SUPERSET_SECRET_KEY)"
+  ROW_LIMIT: 50000
+  WTF_CSRF_ENABLED: true
+  SQLALCHEMY_POOL_SIZE: 10
+```
+
+Each key is injected verbatim into `superset_config.py`. String values are quoted; non-string values
+(integers, booleans) are rendered as-is.
+
+**`featureFlags.*` — feature flag overrides:**
+
+```yaml
+featureFlags:
+  ALERT_REPORTS: true
+  DASHBOARD_RBAC: true
+  ENABLE_TEMPLATE_PROCESSING: false
+```
+
+This is equivalent to setting `FEATURE_FLAGS = {...}` in `superset_config.py`, but is more readable and
+schema-validated.
+
+### 5. `values.schema.json` — early validation
+
+The chart now ships a `values.schema.json` that validates the values you provide. Wrong types (e.g., a string
+where an integer is expected) or unknown keys in structured sections will cause `helm install`/`helm upgrade`
+to fail immediately with a descriptive error instead of producing a broken deployment.
+
+If you get a validation error after upgrading, check that your overridden values match the types documented in
+`values.yaml` and the schema.
