+description: Apache Superset development standards and guidelines for Cursor IDE
+globs: ["**/*.py", "**/*.ts", "**/*.tsx", "**/*.js", "**/*.jsx", "**/*.sql", "**/*.md"]

+---
+
+# Apache Superset Development Standards for Cursor IDE
+
+Apache Superset is a data visualization platform with Flask/Python backend and React/TypeScript frontend.
+
+## ⚠️ CRITICAL: Ongoing Refactors (What NOT to Do)
+
+**These migrations are actively happening - avoid deprecated patterns:**
+
+### Frontend Modernization
+- **NO `any` types** - Use proper TypeScript types
+- **NO JavaScript files** - Convert to TypeScript (.ts/.tsx)
+- **NO Enzyme** - Use React Testing Library/Jest (Enzyme fully removed)
+- **Use @superset-ui/core** - Don't import Ant Design directly
+
+### Testing Strategy Migration
+- **Prefer unit tests** over integration tests
+- **Prefer integration tests** over Cypress end-to-end tests
+- **Cypress is last resort** - Actively moving away from Cypress
+- **Use Jest + React Testing Library** for component testing
+
+### Backend Type Safety
+- **Add type hints** - All new Python code needs proper typing
+- **MyPy compliance** - Run `pre-commit run mypy` to validate
+- **SQLAlchemy typing** - Use proper model annotations
+
+## Code Standards
+
+### TypeScript Frontend
+- **NO `any` types** - Use proper TypeScript
+- **Functional components** with hooks
+- **@superset-ui/core** for UI components (not direct antd)
+- **Jest** for testing (NO Enzyme)
+- **Redux** for global state, hooks for local
+
+### Python Backend
+- **Type hints required** for all new code
+- **MyPy compliant** - run `pre-commit run mypy`
+- **SQLAlchemy models** with proper typing
+- **pytest** for testing
+
+### Apache License Headers
+- **New files require ASF license headers** - When creating new code files, include the standard Apache Software Foundation license header
+- **LLM instruction files are excluded** - Files like LLMS.md, CLAUDE.md, etc. are in `.rat-excludes` to avoid header token overhead
+

+└── UPDATING.md                 # Breaking changes log
+```
+
+## Architecture Patterns
+
+### Dataset-Centric Approach
+Charts built from enriched datasets containing:
+- Dimension columns with labels/descriptions
+- Predefined metrics as SQL expressions
+- Self-service analytics within defined contexts
+
+### Security & Features
+- **RBAC**: Role-based access via Flask-AppBuilder
+- **Feature flags**: Control feature rollouts
+- **Row-level security**: SQL-based data access control
+
+## Test Utilities
+
+### Python Test Helpers
+- **`SupersetTestCase`** - Base class in `tests/integration_tests/base_tests.py`
+- **`@with_config`** - Config mocking decorator
+- **`@with_feature_flags`** - Feature flag testing
+- **`login_as()`, `login_as_admin()`** - Authentication helpers
+- **`create_dashboard()`, `create_slice()`** - Data setup utilities
+
+### TypeScript Test Helpers
+- **`superset-frontend/spec/helpers/testing-library.tsx`** - Custom render() with providers
+- **`createWrapper()`** - Redux/Router/Theme wrapper
+- **`selectOption()`** - Select component helper
+- **React Testing Library** - NO Enzyme (removed)
+
+## Pre-commit Validation
+
+**Use pre-commit hooks for quality validation:**
+
+```bash
+# Install hooks
+pre-commit install
+
+# Quick validation (faster than --all-files)
+pre-commit run                    # Staged files only
+pre-commit run mypy              # Python type checking
+pre-commit run prettier          # Code formatting
+pre-commit run eslint            # Frontend linting
+```
+
+## Development Guidelines
+
+- **Documentation**: Update docs/ for any user-facing changes
+- **Breaking Changes**: Add to UPDATING.md
+- **Docstrings**: Required for new functions/classes
+- **Follow existing patterns**: Mimic code style, use existing libraries and utilities
+- **Type Safety**: This codebase is actively modernizing toward full TypeScript and type safety
+- **Always run `pre-commit run`** to validate changes before committing
+
+---
+
+**Note**: This codebase is actively modernizing toward full TypeScript and type safety. Always run `pre-commit run` to validate changes. Follow the ongoing refactors section to avoid deprecated patterns.

+# Superset Development with GitHub Codespaces
+
+For complete documentation on using GitHub Codespaces with Apache Superset, please see:
+
+**[Setting up a Development Environment - GitHub Codespaces](https://superset.apache.org/docs/contributing/development#github-codespaces-cloud-development)**
+
+## Pre-installed Development Environment
+
+When you create a new Codespace from this repository, it automatically:
+
+1. **Creates a Python virtual environment** using `uv venv`
+2. **Installs all development dependencies** via `uv pip install -r requirements/development.txt`
+3. **Sets up pre-commit hooks** with `pre-commit install`
+4. **Activates the virtual environment** automatically in all terminals
+
+The virtual environment is located at `/workspaces/{repository-name}/.venv` and is automatically activated through environment variables set in the devcontainer configuration.

+**These migrations are actively happening - avoid deprecated patterns:**
+
+### Frontend Modernization
+- **NO `any` types** - Use proper TypeScript types
+- **NO JavaScript files** - Convert to TypeScript (.ts/.tsx)
+- **Use @superset-ui/core** - Don't import Ant Design directly, prefer Ant Design component wrappers from @superset-ui/core/components
+- **Use antd theming tokens** - Prefer antd tokens over legacy theming tokens
+- **Avoid custom css and styles** - Follow antd best practices and avoid styling and custom CSS whenever possible
+
+### Testing Strategy Migration
+- **Prefer unit tests** over integration tests
+- **Prefer integration tests** over Cypress end-to-end tests
+- **Cypress is last resort** - Actively moving away from Cypress
+- **Use Jest + React Testing Library** for component testing
+- **Use `test()` instead of `describe()`** - Follow [avoid nesting when testing](https://kentcdodds.com/blog/avoid-nesting-when-youre-testing) principles
+
+### Backend Type Safety
+- **Add type hints** - All new Python code needs proper typing
+- **MyPy compliance** - Run `pre-commit run mypy` to validate
+- **SQLAlchemy typing** - Use proper model annotations
+
+### UUID Migration
+- **Prefer UUIDs over auto-incrementing IDs** - New models should use UUID primary keys
+- **External API exposure** - Use UUIDs in public APIs instead of internal integer IDs
+- **Existing models** - Add UUID fields alongside integer IDs for gradual migration
+

+
+## Code Standards
+
+### TypeScript Frontend
+- **Avoid `any` types** - Use proper TypeScript, reuse existing types
+- **Functional components** with hooks
+- **@superset-ui/core** for UI components (not direct antd)
+- **Jest** for testing (NO Enzyme)
+- **Redux** for global state where it exists, hooks for local
+
+### Python Backend  
+- **Type hints required** for all new code
+- **MyPy compliant** - run `pre-commit run mypy`
+- **SQLAlchemy models** with proper typing
+- **pytest** for testing
+
+### Apache License Headers
+- **New files require ASF license headers** - When creating new code files, include the standard Apache Software Foundation license header
+- **LLM instruction files are excluded** - Files like LLMS.md, CLAUDE.md, etc. are in `.rat-excludes` to avoid header token overhead
+
+## Documentation Requirements
+
+- **docs/**: Update for any user-facing changes
+- **UPDATING.md**: Add breaking changes here
+- **Docstrings**: Required for new functions/classes
+
+## Architecture Patterns
+
+### Security & Features
+- **RBAC**: Role-based access via Flask-AppBuilder
+- **Feature flags**: Control feature rollouts
+- **Row-level security**: SQL-based data access control
+
+## Test Utilities
+
+### Python Test Helpers
+- **`SupersetTestCase`** - Base class in `tests/integration_tests/base_tests.py`
+- **`@with_config`** - Config mocking decorator
+- **`@with_feature_flags`** - Feature flag testing
+- **`login_as()`, `login_as_admin()`** - Authentication helpers
+- **`create_dashboard()`, `create_slice()`** - Data setup utilities
+
+### TypeScript Test Helpers
+- **`superset-frontend/spec/helpers/testing-library.tsx`** - Custom render() with providers
+- **`createWrapper()`** - Redux/Router/Theme wrapper
+- **`selectOption()`** - Select component helper
+- **React Testing Library** - NO Enzyme (removed)
+
+### Test Database Patterns
+- **Mock patterns**: Use `MagicMock()` for config objects, avoid `AsyncMock` for synchronous code
+- **API tests**: Update expected columns when adding new model fields
+
+### Running Tests
+```bash
+# Frontend
+npm run test                           # All tests
+npm run test -- filename.test.tsx     # Single file
+
+# Backend  
+pytest                                 # All tests
+pytest tests/unit_tests/specific_test.py  # Single file
+pytest tests/unit_tests/               # Directory
+
+# If pytest fails with database/setup issues, ask the user to run test environment setup
+```
+
+## Environment Validation
+
+**Quick Setup Check (run this first):**
+
+```bash
+# Verify Superset is running
+curl -f http://localhost:8088/health || echo "❌ Setup required - see https://superset.apache.org/docs/contributing/development#working-with-llms"
+```
+
+**If health checks fail:**
+"It appears you aren't set up properly. Please refer to the [Working with LLMs](https://superset.apache.org/docs/contributing/development#working-with-llms) section in the development docs for setup instructions."
+
+**Key Project Files:**
+- `superset-frontend/package.json` - Frontend build scripts (`npm run dev` on port 9000, `npm run test`, `npm run lint`)
+- `pyproject.toml` - Python tooling (ruff, mypy configs)
+- `requirements/` folder - Python dependencies (base.txt, development.txt)
+
+## SQLAlchemy Query Best Practices  
+- **Use negation operator**: `~Model.field` instead of `== False` to avoid ruff E712 errors
+- **Example**: `~Model.is_active` instead of `Model.is_active == False`
+
+## Pre-commit Validation
+
+**Use pre-commit hooks for quality validation:**
+
+```bash
+# Install hooks
+pre-commit install
+
+# IMPORTANT: Stage your changes first!
+git add .                        # Pre-commit only checks staged files
+
+# Quick validation (faster than --all-files)
+pre-commit run                   # Staged files only
+pre-commit run mypy              # Python type checking
+pre-commit run prettier          # Code formatting
+pre-commit run eslint            # Frontend linting
+```
+
+**Important pre-commit usage notes:**
+- **Stage files first**: Run `git add .` before `pre-commit run` to check only changed files (much faster)
+- **Virtual environment**: Activate your Python virtual environment before running pre-commit
+  ```bash
+  # Common virtual environment locations (yours may differ):
+  source .venv/bin/activate      # if using .venv
+  source venv/bin/activate       # if using venv
+  source ~/venvs/superset/bin/activate  # if using a central location
+  ```
+  If you get a "command not found" error, ask the user which virtual environment to activate
+- **Auto-fixes**: Some hooks auto-fix issues (e.g., trailing whitespace). Re-run after fixes are applied
+
+## Common File Patterns
+
+### API Structure
+- **`/api.py`** - REST endpoints with decorators and OpenAPI docstrings
+- **`/schemas.py`** - Marshmallow validation schemas for OpenAPI spec
+- **`/commands/`** - Business logic classes with @transaction() decorators
+- **`/models/`** - SQLAlchemy database models
+- **OpenAPI docs**: Auto-generated at `/swagger/v1` from docstrings and schemas
+
+### Migration Files
+- **Location**: `superset/migrations/versions/`
+- **Naming**: `YYYY-MM-DD_HH-MM_hash_description.py`
+- **Utilities**: Use helpers from `superset.migrations.shared.utils` for database compatibility
+- **Pattern**: Import utilities instead of raw SQLAlchemy operations
+
+## Platform-Specific Instructions
+
+- **[CLAUDE.md](CLAUDE.md)** - For Claude/Anthropic tools
+- **[.github/copilot-instructions.md](.github/copilot-instructions.md)** - For GitHub Copilot  
+- **[GEMINI.md](GEMINI.md)** - For Google Gemini tools
+- **[GPT.md](GPT.md)** - For OpenAI/ChatGPT tools
+- **[.cursor/rules/dev-standard.mdc](.cursor/rules/dev-standard.mdc)** - For Cursor editor
+
+---
+
+**LLM Note**: This codebase is actively modernizing toward full TypeScript and type safety. Always run `pre-commit run` to validate changes. Follow the ongoing refactors section to avoid deprecated patterns.

 assists people when migrating to a new version.
 
 ## Next
-
+- [34871](https://github.com/apache/superset/pull/34871): Fixed Jest test hanging issue from Ant Design v5 upgrade. MessageChannel is now mocked in test environment to prevent rc-overflow from causing Jest to hang. Test environment only - no production impact.
+- [34782](https://github.com/apache/superset/pull/34782): Dataset exports now include the dataset ID in their file name (similar to charts and dashboards). If managing assets as code, make sure to rename existing dataset YAMLs to include the ID (and avoid duplicated files).
+- [34536](https://github.com/apache/superset/pull/34536): The `ENVIRONMENT_TAG_CONFIG` color values have changed to support only Ant Design semantic colors. Update your `superset_config.py`:
+  - Change `"error.base"` to just `"error"` after this PR
+  - Change any hex color values to one of: `"success"`, `"processing"`, `"error"`, `"warning"`, `"default"`
+  - Custom colors are no longer supported to maintain consistency with Ant Design components
+- [34561](https://github.com/apache/superset/pull/34561) Added tiled screenshot functionality for Playwright-based reports to handle large dashboards more efficiently. When enabled (default: `SCREENSHOT_TILED_ENABLED = True`), dashboards with 20+ charts or height exceeding 5000px will be captured using multiple viewport-sized tiles and combined into a single image. This improves report generation performance and reliability for large dashboards.
+Note: Pillow is now a required dependency (previously optional) to support image processing for tiled screenshots.
+`thumbnails` optional dependency is now deprecated and will be removed in the next major release (7.0).
+- [33084](https://github.com/apache/superset/pull/33084) The DISALLOWED_SQL_FUNCTIONS configuration now includes additional potentially sensitive database functions across PostgreSQL, MySQL, SQLite, MS SQL Server, and ClickHouse. Existing queries using these functions may now be blocked. Review your SQL Lab queries and dashboards if you encounter "disallowed function" errors after upgrading
+- [34235](https://github.com/apache/superset/pull/34235) CSV exports now use `utf-8-sig` encoding by default to include a UTF-8 BOM, improving compatibility with Excel.
+- [34258](https://github.com/apache/superset/pull/34258) changing the default in Dockerfile to INCLUDE_CHROMIUM="false" (from "true") in the past. This ensures the `lean` layer is lean by default, and people can opt-in to the `chromium` layer by setting the build arg `INCLUDE_CHROMIUM=true`. This is a breaking change for anyone using the `lean` layer, as it will no longer include Chromium by default.
+- [34204](https://github.com/apache/superset/pull/33603) OpenStreetView has been promoted as the new default for Deck.gl visualization since it can be enabled by default without requiring an API key. If you have Mapbox set up and want to disable OpenStreeView in your environment, please follow the steps documented here [https://superset.apache.org/docs/configuration/map-tiles].
 - [33116](https://github.com/apache/superset/pull/33116) In Echarts Series charts (e.g. Line, Area, Bar, etc.) charts, the `x_axis_sort_series` and `x_axis_sort_series_ascending` form data items have been renamed with `x_axis_sort` and `x_axis_sort_asc`.
   There's a migration added that can potentially affect a significant number of existing charts.
 - [32317](https://github.com/apache/superset/pull/32317) The horizontal filter bar feature is now out of testing/beta development and its feature flag `HORIZONTAL_FILTER_BAR` has been removed.
 - [31590](https://github.com/apache/superset/pull/31590) Marks the begining of intricate work around supporting dynamic Theming, and breaks support for [THEME_OVERRIDES](https://github.com/apache/superset/blob/732de4ac7fae88e29b7f123b6cbb2d7cd411b0e4/superset/config.py#L671) in favor of a new theming system based on AntD V5. Likely this will be in disrepair until settling over the 5.x lifecycle.
 - [32432](https://github.com/apache/superset/pull/31260) Moves the List Roles FAB view to the frontend and requires `FAB_ADD_SECURITY_API` to be enabled in the configuration and `superset init` to be executed.
+- [34319](https://github.com/apache/superset/pull/34319) Drill to Detail and Drill By is now supported in Embedded mode, and also with the `DASHBOARD_RBAC` FF. If you don't want to expose these features in Embedded / `DASHBOARD_RBAC`, make sure the roles used for Embedded / `DASHBOARD_RBAC`don't have the required permissions to perform D2D actions.

+# Lightweight docker-compose for running multiple Superset instances
+# This includes only essential services: database and Superset app (no Redis)
+#
+# RUNNING SUPERSET:
+# 1. Start services: docker-compose -f docker-compose-light.yml up
+# 2. Access at: http://localhost:9001 (or NODE_PORT if specified)
+#
+# RUNNING MULTIPLE INSTANCES:
+# - Use different project names: docker-compose -p project1 -f docker-compose-light.yml up
+# - Use different NODE_PORT values: NODE_PORT=9002 docker-compose -p project2 -f docker-compose-light.yml up
+# - Volumes are isolated by project name (e.g., project1_db_home_light, project2_db_home_light)
+# - Database name is intentionally different (superset_light) to prevent accidental cross-connections
+#
+# RUNNING TESTS WITH PYTEST:
+# Tests run in an isolated environment with a separate test database.
+# The pytest-runner service automatically creates and initializes the test database on first use.
+#
+# Basic usage:
+#   docker-compose -f docker-compose-light.yml run --rm pytest-runner pytest tests/unit_tests/
+#
+# Run specific test file:
+#   docker-compose -f docker-compose-light.yml run --rm pytest-runner pytest tests/unit_tests/test_foo.py
+#
+# Run with pytest options:
+#   docker-compose -f docker-compose-light.yml run --rm pytest-runner pytest -v -s -x tests/
+#
+# Force reload test database and run tests (when tests are failing due to bad state):
+#   docker-compose -f docker-compose-light.yml run --rm -e FORCE_RELOAD=true pytest-runner pytest tests/
+#
+# Run any command in test environment:
+#   docker-compose -f docker-compose-light.yml run --rm pytest-runner bash
+#   docker-compose -f docker-compose-light.yml run --rm pytest-runner pytest --collect-only
+#
+# For parallel test execution with different projects:
+#   docker-compose -p project1 -f docker-compose-light.yml run --rm pytest-runner pytest tests/
+#
+# DEVELOPMENT TIPS:
+# - First test run takes ~20-30 seconds (database creation + initialization)
+# - Subsequent runs are fast (~2-3 seconds startup)
+# - Use FORCE_RELOAD=true when you need a clean test database
+# - Tests use SimpleCache instead of Redis (no Redis required)
+# - Set SUPERSET_LOG_LEVEL=debug in docker/.env-local for detailed logs

docs/README.md

@@ -21,3 +21,183 @@ This is the public documentation site for Superset, built using
 [Docusaurus 3](https://docusaurus.io/). See
 [CONTRIBUTING.md](../CONTRIBUTING.md#documentation) for documentation on
 contributing to documentation.
+
+## Version Management
+
+The Superset documentation site uses Docusaurus versioning with three independent versioned sections:
+
+- **Main Documentation** (`/docs/`) - Core Superset documentation
+- **Developer Portal** (`/developer_portal/`) - Developer guides and tutorials  
+- **Component Playground** (`/components/`) - Interactive component examples (currently disabled)
+
+Each section maintains its own version history and can be versioned independently.
+
+### Creating a New Version
+
+To create a new version for any section, use the Docusaurus version command with the appropriate plugin ID or use our automated scripts:
+
+#### 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.
+
+```bash
+# Main Documentation
+yarn version:add:docs 1.2.0
+
+# Developer Portal
+yarn version:add:developer_portal 1.2.0
+
+# Component Playground (when enabled)
+yarn version:add:components 1.2.0
+```
+
+**Do NOT use** the native Docusaurus commands directly (`yarn docusaurus docs:version`), as they will:
+- ❌ Create version files but NOT update `versions-config.json`
+- ❌ Cause versions to not appear in dropdown menus
+- ❌ Require manual fixes to synchronize the configuration
+
+### Managing Versions
+
+#### With Automated Scripts
+The automated scripts handle all configuration updates automatically. No manual editing required!
+
+#### Manual Configuration
+If creating versions manually, you'll need to:
+
+1. **Update `versions-config.json`** (or `docusaurus.config.ts` if not using dynamic config):
+   - Add version to `onlyIncludeVersions` array
+   - Add version metadata to `versions` object
+   - Update `lastVersion` if needed
+
+2. **Files Created by Versioning**:
+   When a new version is created, Docusaurus generates:
+   - **Versioned docs folder**: `[section]_versioned_docs/version-X.X.X/`
+   - **Versioned sidebars**: `[section]_versioned_sidebars/version-X.X.X-sidebars.json`
+   - **Versions list**: `[section]_versions.json`
+
+   Note: For main docs, the prefix is omitted (e.g., `versioned_docs/` instead of `docs_versioned_docs/`)
+
+3. **Important**: After adding a version, restart the development server to see changes:
+   ```bash
+   yarn stop
+   yarn start
+   ```
+
+### Removing a Version
+
+#### Using Automated Scripts (Recommended)
+```bash
+# Main Documentation
+yarn version:remove:docs 1.0.0
+
+# Developer Portal
+yarn version:remove:developer_portal 1.0.0
+
+# Component Playground
+yarn version:remove:components 1.0.0
+```
+
+#### Manual Removal
+To manually remove a version:
+
+1. **Delete the version folder** from the appropriate location:
+   - Main docs: `versioned_docs/version-X.X.X/` (no prefix for main)
+   - Developer Portal: `developer_portal_versioned_docs/version-X.X.X/`
+   - Components: `components_versioned_docs/version-X.X.X/`
+
+2. **Delete the version metadata file**:
+   - Main docs: `versioned_sidebars/version-X.X.X-sidebars.json` (no prefix)
+   - Developer Portal: `developer_portal_versioned_sidebars/version-X.X.X-sidebars.json`
+   - Components: `components_versioned_sidebars/version-X.X.X-sidebars.json`
+
+3. **Update the versions list file**:
+   - Main docs: `versions.json`
+   - Developer Portal: `developer_portal_versions.json`
+   - Components: `components_versions.json`
+
+4. **Update configuration**:
+   - If using dynamic config: Update `versions-config.json`
+   - If using static config: Update `docusaurus.config.ts`
+
+5. **Restart the server** to see changes
+
+### Version Configuration Examples
+
+#### Main Documentation (default plugin)
+```typescript
+docs: {
+  includeCurrentVersion: true,
+  lastVersion: 'current',  // Makes /docs/ show Next version
+  onlyIncludeVersions: ['current', '1.1.0', '1.0.0'],
+  versions: {
+    current: {
+      label: 'Next',
+      path: '',  // Empty path for default routing
+      banner: 'unreleased',
+    },
+    '1.1.0': {
+      label: '1.1.0',
+      path: '1.1.0',
+      banner: 'none',
+    },
+  },
+}
+```
+
+#### Developer Portal & Components (custom plugins)
+```typescript
+{
+  id: 'developer_portal',
+  path: 'developer_portal',
+  routeBasePath: 'developer_portal',
+  includeCurrentVersion: true,
+  lastVersion: '1.1.0',  // Default version
+  onlyIncludeVersions: ['current', '1.1.0', '1.0.0'],
+  versions: {
+    current: {
+      label: 'Next',
+      path: 'next',
+      banner: 'unreleased',
+    },
+    '1.1.0': {
+      label: '1.1.0',
+      path: '1.1.0',
+      banner: 'none',
+    },
+  },
+}
+```
+
+### Best Practices
+
+1. **Version naming**: Use semantic versioning (e.g., 1.0.0, 1.1.0, 2.0.0)
+2. **Version banners**: Use `'unreleased'` for development versions, `'none'` for stable releases
+3. **Limit displayed versions**: Use `onlyIncludeVersions` to show only relevant versions
+4. **Test locally**: Always test version changes locally before deploying
+5. **Independent versioning**: Each section can have different version numbers and release cycles
+
+### Troubleshooting
+
+#### Version Not Showing After Creation
+
+If you accidentally used `yarn docusaurus docs:version` instead of `yarn version:add`:
+1. **Problem**: The version files were created but `versions-config.json` wasn't updated
+2. **Solution**: Either:
+   - Revert the changes: `git restore versions.json && rm -rf versioned_docs/ versioned_sidebars/`
+   - Then use the correct command: `yarn version:add:docs <version>`
+
+For other issues:
+- **Restart the server**: Changes to version configuration require a server restart
+- **Check config file**: Ensure `versions-config.json` includes the new version
+- **Verify files exist**: Check that versioned docs folder was created
+
+#### Broken Links in Versioned Documentation
+When creating a new version, links in the documentation are preserved as-is. Common issues:
+- **Cross-section links**: Links between sections (e.g., from developer_portal to docs) need to be version-aware
+- **Absolute vs relative paths**: Use relative paths within the same section
+- **Version-specific URLs**: Update hardcoded URLs to use version variables
+
+To fix broken links:
+1. Use `type: 'doc'` with `docId` for version-aware navigation in navbar
+2. Use relative paths within the same documentation section
+3. Test all versions after creation to identify broken links

+
+# Bar Chart Component
+
+The Bar Chart component is used to visualize categorical data with rectangular bars.
+
+## Props
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `data` | `array` | `[]` | Array of data objects to visualize |
+| `width` | `number` | `800` | Width of the chart in pixels |
+| `height` | `number` | `600` | Height of the chart in pixels |
+| `xField` | `string` | - | Field name for x-axis values |
+| `yField` | `string` | - | Field name for y-axis values |
+| `colorField` | `string` | - | Field name for color encoding |
+| `colorScheme` | `string` | `'supersetColors'` | Color scheme to use |
+| `showLegend` | `boolean` | `true` | Whether to show the legend |
+| `showGrid` | `boolean` | `true` | Whether to show grid lines |
+| `labelPosition` | `string` | `'top'` | Position of bar labels: 'top', 'middle', 'bottom' |
+
+## Examples
+
+### Basic Bar Chart
+
+```jsx
+import { BarChart } from '@superset-ui/chart-components';
+
+const data = [
+  { category: 'A', value: 10 },
+  { category: 'B', value: 20 },
+  { category: 'C', value: 15 },
+  { category: 'D', value: 25 },
+];
+
+function Example() {
+  return (
+    <BarChart
+      data={data}
+      width={800}
+      height={400}
+      xField="category"
+      yField="value"
+      colorScheme="supersetColors"
+    />
+  );
+}
+```
+
+### Grouped Bar Chart
+
+```jsx
+import { BarChart } from '@superset-ui/chart-components';
+
+const data = [
+  { category: 'A', group: 'Group 1', value: 10 },
+  { category: 'A', group: 'Group 2', value: 15 },
+  { category: 'B', group: 'Group 1', value: 20 },
+  { category: 'B', group: 'Group 2', value: 25 },
+  { category: 'C', group: 'Group 1', value: 15 },
+  { category: 'C', group: 'Group 2', value: 10 },
+];
+
+function Example() {
+  return (
+    <BarChart
+      data={data}
+      width={800}
+      height={400}
+      xField="category"
+      yField="value"
+      colorField="group"
+      colorScheme="supersetColors"
+    />
+  );
+}
+```
+
+## Best Practices
+
+- Use bar charts when comparing quantities across categories
+- Sort bars by value for better readability, unless there's a natural order to the categories
+- Use consistent colors for the same categories across different charts
+- Consider using horizontal bar charts when category labels are long

+
+# Superset Component Library
+
+Welcome to the Apache Superset Component Library documentation. This section provides comprehensive documentation for all the UI components, chart components, and layout components used in Superset.
+
+## What is the Component Library?
+
+The Component Library is a collection of reusable UI components that are used to build the Superset user interface. These components are designed to be consistent, accessible, and easy to use.
+
+## Component Categories
+
+The Component Library is organized into the following categories:
+
+### UI Components
+
+Basic UI components like buttons, inputs, dropdowns, and other form elements.
+
+### Chart Components
+
+Visualization components used to render different types of charts and graphs.
+
+### Layout Components
+
+Components used for page layout, such as containers, grids, and navigation elements.
+
+## Versioning
+
+The Component Library documentation follows its own versioning scheme, independent from the main Superset documentation. This allows us to update the component documentation as the components evolve, without affecting the main documentation.
+
+## Getting Started
+
+Browse the sidebar to explore the different components available in the library. Each component documentation includes:
+
+- Component description and purpose
+- Props and configuration options
+- Usage examples
+- Best practices

+| `justify` | `string` | `'start'` | Horizontal alignment for this row |
+| `align` | `string` | `'top'` | Vertical alignment for this row |
+
+### Col Props
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `span` | `number` | - | Number of columns the grid item spans |
+| `offset` | `number` | `0` | Number of columns the grid item is offset |
+| `xs`, `sm`, `md`, `lg`, `xl` | `number` or `object` | - | Responsive props for different screen sizes |
+
+## Examples
+
+### Basic Grid
+
+```jsx
+import { Grid, Row, Col } from '@superset-ui/core';
+
+function Example() {
+  return (
+    <Grid>
+      <Row gutter={16}>
+        <Col span={8}>
+          <div>Column 1</div>
+        </Col>
+        <Col span={8}>
+          <div>Column 2</div>
+        </Col>
+        <Col span={8}>
+          <div>Column 3</div>
+        </Col>
+      </Row>
+    </Grid>
+  );
+}
+```
+
+### Responsive Grid
+
+```jsx
+import { Grid, Row, Col } from '@superset-ui/core';
+
+function Example() {
+  return (
+    <Grid>
+      <Row gutter={[16, 24]}>
+        <Col xs={24} sm={12} md={8} lg={6}>
+          <div>Responsive Column 1</div>
+        </Col>
+        <Col xs={24} sm={12} md={8} lg={6}>
+          <div>Responsive Column 2</div>
+        </Col>
+        <Col xs={24} sm={12} md={8} lg={6}>
+          <div>Responsive Column 3</div>
+        </Col>
+        <Col xs={24} sm={12} md={8} lg={6}>
+          <div>Responsive Column 4</div>
+        </Col>
+      </Row>
+    </Grid>
+  );
+}
+```
+
+## Best Practices
+
+- Use the Grid system for complex layouts that need to be responsive
+- Specify column widths for different screen sizes to ensure proper responsive behavior
+- Use gutters to create appropriate spacing between grid items
+- Keep the grid structure consistent throughout your application
+- Consider using the grid system for dashboard layouts to ensure consistent spacing and alignment

+title: Button Component
+sidebar_position: 1
+---
+
+import { StoryExample, StoryWithControls } from '../../src/components/StorybookWrapper';
+import { Button } from '../../../superset-frontend/packages/superset-ui-core/src/components/Button';
+
+# Button Component
+
+The Button component is a fundamental UI element used throughout Superset for user interactions.
+
+## Basic Usage
+
+The default button with primary styling:
+<StoryExample
+  component={() => (
+    <Button buttonStyle="primary" onClick={() => console.log('Clicked!')}>
+      Click Me
+    </Button>
+  )}
+/>
+
+## Interactive Example
+
+<StoryWithControls
+  component={({ buttonStyle, buttonSize, label, disabled }) => (
+    <Button
+      buttonStyle={buttonStyle}
+      buttonSize={buttonSize}
+      disabled={disabled}
+      onClick={() => console.log('Clicked!')}
+    >
+      {label}
+    </Button>
+  )}
+  props={{
+    buttonStyle: 'primary',
+    buttonSize: 'default',
+    label: 'Click Me',
+    disabled: false
+  }}
+  controls={[
+    {
+      name: 'buttonStyle',
+      label: 'Button Style',
+      type: 'select',
+      options: ['primary', 'secondary', 'tertiary', 'success', 'warning', 'danger', 'default', 'link', 'dashed']
+    },
+    {
+      name: 'buttonSize',
+      label: 'Button Size',
+      type: 'select',
+      options: ['default', 'small', 'xsmall']
+    },
+    {
+      name: 'label',
+      label: 'Button Text',
+      type: 'text'
+    },
+    {
+      name: 'disabled',
+      label: 'Disabled',
+      type: 'boolean'
+    }
+  ]}
+/>
+
+## Props
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `buttonStyle` | `'primary' \| 'secondary' \| 'tertiary' \| 'success' \| 'warning' \| 'danger' \| 'default' \| 'link' \| 'dashed'` | `'default'` | Button style |
+| `buttonSize` | `'default' \| 'small' \| 'xsmall'` | `'default'` | Button size |
+| `disabled` | `boolean` | `false` | Whether the button is disabled |
+| `cta` | `boolean` | `false` | Whether the button is a call-to-action button |
+| `tooltip` | `ReactNode` | - | Tooltip content |
+| `placement` | `TooltipProps['placement']` | - | Tooltip placement |
+| `onClick` | `function` | - | Callback when button is clicked |
+| `href` | `string` | - | Turns button into an anchor link |
+| `target` | `string` | - | Target attribute for anchor links |
+
+## Usage
+
+```jsx
+import Button from 'src/components/Button';
+
+function MyComponent() {
+  return (
+    <Button
+      buttonStyle="primary"
+      onClick={() => console.log('Button clicked')}
+    >
+      Click Me
+    </Button>
+  );
+}
+```
+
+## Button Styles
+
+Superset provides a variety of button styles for different purposes:
+
+- **Primary**: Used for primary actions
+- **Secondary**: Used for secondary actions
+- **Tertiary**: Used for less important actions
+- **Success**: Used for successful or confirming actions
+- **Warning**: Used for actions that require caution
+- **Danger**: Used for destructive actions
+- **Link**: Used for navigation
+- **Dashed**: Used for adding new items or features
+
+## Button Sizes
+
+Buttons come in three sizes:
+
+- **Default**: Standard size for most use cases
+- **Small**: Compact size for tight spaces
+- **XSmall**: Extra small size for very limited spaces
+
+## Best Practices
+
+- Use primary buttons for the main action in a form or page
+- Use secondary buttons for alternative actions
+- Use danger buttons for destructive actions
+- Limit the number of primary buttons on a page to avoid confusion
+- Use consistent button styles throughout your application
+- Add tooltips to buttons when their purpose might not be immediately clear

+  Tooltip,
+  Icon,
+  // ... many more
+} from '@apache-superset/core';
+```
+
+### Example Component Usage
+
+```typescript
+import { Button, Alert } from '@apache-superset/core';
+
+function MyExtensionPanel() {
+  return (
+    <div>
+      <Alert
+        message="Extension Loaded"
+        description="Your extension is ready to use"
+        type="success"
+      />
+      <Button
+        type="primary"
+        onClick={() => console.log('Clicked!')}
+      >
+        Execute Action
+      </Button>
+    </div>
+  );
+}
+```
+
+## Storage API
+
+Provides persistent storage for extension data.
+
+### Local Storage
+
+```typescript
+// Store data
+storage.local.set(key: string, value: any): Promise<void>
+
+// Retrieve data
+storage.local.get(key: string): Promise<any>
+
+// Remove data
+storage.local.remove(key: string): Promise<void>
+
+// Clear all extension data
+storage.local.clear(): Promise<void>
+```
+
+### Workspace Storage
+
+Workspace storage is shared across all users for collaborative features.
+
+```typescript
+storage.workspace.set(key: string, value: any): Promise<void>
+storage.workspace.get(key: string): Promise<any>
+storage.workspace.remove(key: string): Promise<void>
+```
+
+## Network API
+
+Utilities for making API calls to Superset.
+
+### fetch
+
+Enhanced fetch with CSRF token handling.
+
+```typescript
+network.fetch(url: string, options?: RequestInit): Promise<Response>
+```
+
+### API Client
+
+Type-safe API client for Superset endpoints.
+
+```typescript
+// Get chart data
+network.api.charts.get(id: number): Promise<Chart>
+
+// Query database
+network.api.sqlLab.execute(
+  databaseId: number,
+  query: string
+): Promise<QueryResult>
+
+// Get datasets
+network.api.datasets.list(): Promise<Dataset[]>
+```
+
+## Utility Functions
+
+### Formatting
+
+```typescript
+// Format numbers
+utils.formatNumber(value: number, format?: string): string
+
+// Format dates
+utils.formatDate(date: Date, format?: string): string
+
+// Format SQL
+utils.formatSQL(sql: string): string
+```
+
+### Validation
+
+```typescript
+// Validate SQL syntax
+utils.validateSQL(sql: string): ValidationResult
+
+// Check if valid database ID
+utils.isValidDatabaseId(id: any): boolean
+```
+
+## TypeScript Types
+
+Import common types for type safety:
+
+```typescript
+import type {
+  Database,
+  Dataset,
+  Chart,
+  Dashboard,
+  Query,
+  QueryResult,
+  Tab,
+  Panel,
+  User,
+  Role,
+  Permission,
+  ExtensionContext,
+  Disposable,
+  Event,
+  // ... more types
+} from '@apache-superset/core';
+```
+
+## Extension Context
+
+The context object passed to your extension's `activate` function:
+
+```typescript
+interface ExtensionContext {
+  // Subscription management
+  subscriptions: Disposable[];
+
+  // Extension metadata
+  extensionId: string;
+  extensionPath: string;
+
+  // API namespaces
+  core: CoreAPI;
+  commands: CommandsAPI;
+  sqlLab: SqlLabAPI;
+  authentication: AuthenticationAPI;
+  extensions: ExtensionsAPI;
+  storage: StorageAPI;
+  network: NetworkAPI;
+  utils: UtilsAPI;
+
+  // Logging
+  logger: Logger;
+}
+```
+
+## Event Handling
+
+Events follow the VS Code pattern with subscribe/dispose:
+
+```typescript
+// Subscribe to event
+const disposable = sqlLab.onDidQueryRun((result) => {
+  // Handle event
+});
+
+// Dispose when done
+disposable.dispose();
+
+// Or add to context for automatic cleanup
+context.subscriptions.push(disposable);
+```
+
+## Best Practices
+
+1. **Always dispose subscriptions** to prevent memory leaks
+2. **Use TypeScript** for better IDE support and type safety
+3. **Handle errors gracefully** with try-catch blocks
+4. **Check permissions** before sensitive operations
+5. **Use provided UI components** for consistency
+6. **Cache API responses** when appropriate
+7. **Validate user input** before processing
+
+## Version Compatibility
+
+The frontend API follows semantic versioning:
+
+- **Major version**: Breaking changes
+- **Minor version**: New features, backward compatible
+- **Patch version**: Bug fixes
+
+Check compatibility in your `extension.json`:
+
+```json
+{
+  "engines": {
+    "@apache-superset/core": "^1.0.0"
+  }
+}
+```

+
+# Extension Architecture Overview
+
+The Superset extension architecture is designed to be modular, secure, and performant. This document provides a comprehensive overview of how extensions work and interact with the Superset host application.
+
+## Core Principles
+
+### 1. Lean Core
+Superset's core remains minimal, with features delegated to extensions wherever possible. Built-in features use the same APIs as external extensions, ensuring API quality through dogfooding.
+
+### 2. Explicit Contribution Points
+All extension points are clearly defined and documented. Extensions declare their capabilities in metadata files, enabling predictable lifecycle management.
+
+### 3. Versioned APIs
+Public interfaces follow semantic versioning, ensuring backward compatibility and safe evolution of the platform.
+
+### 4. Lazy Loading
+Extensions load only when needed, minimizing performance impact and resource consumption.
+
+### 5. Composability
+Architecture patterns and APIs are reusable across different Superset modules, promoting consistency.
+
+### 6. Community-Driven
+The system evolves based on real-world feedback, with new extension points added as needs emerge.
+
+## System Architecture

+    API --> BackendCore
+    Loader --> Manager
+    Manager --> Bundle
+    Frontend --> FrontendCore
+    Backend --> BackendCore
+    CLI --> Bundle
+```
+
+## Key Components
+
+### Host Application
+
+The Superset host application provides:
+
+- **Extension APIs**: Well-defined interfaces for extensions to interact with Superset
+- **Extension Manager**: Handles lifecycle, activation, and deactivation
+- **Module Loader**: Dynamically loads extension code using Webpack Module Federation
+- **Security Context**: Manages permissions and sandboxing for extensions
+
+### Core Packages
+
+#### @apache-superset/core (Frontend)
+- Shared UI components and utilities
+- TypeScript type definitions
+- Frontend API implementations
+- Event system and command registry
+
+#### apache-superset-core (Backend)
+- Python base classes and utilities
+- Database access APIs
+- Security and permission helpers
+- REST API registration
+
+#### apache-superset-extensions-cli
+- Project scaffolding
+- Build and bundling tools
+- Development server
+- Package management
+
+### Extension Structure
+
+Each extension consists of:
+
+- **Metadata** (`extension.json`): Declares capabilities and requirements
+- **Frontend**: React components and TypeScript code
+- **Backend**: Python modules and API endpoints
+- **Assets**: Styles, images, and other resources
+- **Bundle** (`.supx`): Packaged distribution format
+
+## Module Federation
+
+Extensions use Webpack Module Federation for dynamic loading:
+
+```javascript
+// Extension webpack.config.js
+new ModuleFederationPlugin({
+  name: 'my_extension',
+  filename: 'remoteEntry.[contenthash].js',
+  exposes: {
+    './index': './src/index.tsx',
+  },
+  externals: {
+    '@apache-superset/core': 'superset',
+  },
+  shared: {
+    react: { singleton: true },
+    'react-dom': { singleton: true },
+  }
+})
+```
+
+This allows:
+- **Independent builds**: Extensions compile separately from Superset
+- **Shared dependencies**: Common libraries like React aren't duplicated
+- **Dynamic loading**: Extensions load at runtime without rebuilding Superset
+- **Version compatibility**: Extensions declare compatible core versions
+
+## Extension Lifecycle
+
+### 1. Registration
+```typescript
+// Extension registered with host
+extensionManager.register({
+  name: 'my-extension',
+  version: '1.0.0',
+  manifest: manifestData
+});
+```
+
+### 2. Activation
+```typescript
+// activate() called when extension loads
+export function activate(context: ExtensionContext) {
+  // Register contributions
+  const disposables = [];
+
+  // Add panel
+  disposables.push(
+    context.core.registerView('my-panel', MyPanel)
+  );
+
+  // Register command
+  disposables.push(
+    context.commands.registerCommand('my-command', {
+      execute: () => { /* ... */ }
+    })
+  );
+
+  // Store for cleanup
+  context.subscriptions.push(...disposables);
+}
+```
+
+### 3. Runtime
+- Extension responds to events
+- Provides UI components when requested
+- Executes commands when triggered
+- Accesses APIs as needed
+
+### 4. Deactivation
+```typescript
+// Automatic cleanup of registered items
+export function deactivate() {
+  // context.subscriptions automatically disposed
+  // Additional cleanup if needed
+}
+```
+
+## Contribution Types
+
+### Views
+Extensions can add panels and UI components:
+
+```json
+{
+  "views": {
+    "sqllab.panels": [{
+      "id": "my-panel",
+      "name": "My Panel",
+      "icon": "ToolOutlined"
+    }]
+  }
+}
+```
+
+### Commands
+Define executable actions:
+
+```json
+{
+  "commands": [{
+    "command": "my-extension.run",
+    "title": "Run Analysis",
+    "icon": "PlayCircleOutlined"
+  }]
+}
+```
+
+### Menus
+Add items to existing menus:
+
+```json
+{
+  "menus": {
+    "sqllab.editor": {
+      "primary": [{
+        "command": "my-extension.run",
+        "when": "editorHasSelection"
+      }]
+    }
+  }
+}
+```
+
+### API Endpoints
+Register backend REST endpoints:
+
+```python
+from superset_core.api import rest_api
+
+@rest_api.route('/my-endpoint')
+def my_endpoint():
+    return {'data': 'value'}
+```
+
+## Security Model
+
+### Permissions
+- Extensions run with user's permissions
+- No elevation of privileges
+- Access controlled by Superset's RBAC
+
+### Sandboxing
+- Frontend code runs in browser context
+- Backend code runs in Python process
+- Future: Optional sandboxed execution
+
+### Validation
+- Manifest validation on upload
+- Signature verification (future)
+- Dependency scanning
+
+## Performance Considerations
+
+### Lazy Loading
+- Extensions load only when features are accessed
+- Code splitting for large extensions
+- Cached after first load
+
+### Bundle Optimization
+- Tree shaking removes unused code
+- Minification reduces size
+- Compression for network transfer
+
+### Resource Management
+- Automatic cleanup on deactivation
+- Memory leak prevention
+- Event listener management
+
+## Development vs Production
+
+### Development Mode
+```python
+# superset_config.py
+ENABLE_EXTENSIONS = True
+LOCAL_EXTENSIONS = ['/path/to/extension']
+```
+- Hot reloading
+- Source maps
+- Debug logging
+
+### Production Mode
+- Optimized bundles
+- Cached assets
+- Performance monitoring
+
+## Future Enhancements
+
+### Planned Features
+- Enhanced sandboxing
+- Extension marketplace
+- Inter-extension communication
+- Theme contributions
+- Chart type extensions
+
+### API Expansion
+- Dashboard extensions
+- Database connector API
+- Security provider interface
+- Workflow automation
+
+## Best Practices
+
+### Do's
+- ✅ Use TypeScript for type safety
+- ✅ Follow semantic versioning
+- ✅ Handle errors gracefully
+- ✅ Clean up resources properly
+- ✅ Document your extension
+
+### Don'ts
+- ❌ Access private APIs
+- ❌ Modify global state directly
+- ❌ Block the main thread
+- ❌ Store sensitive data insecurely
+- ❌ Assume API stability in 0.x versions

+## Configuration
+
+### Project Configuration
+
+The CLI reads configuration from multiple sources:
+
+1. **extension.json** - Extension metadata
+2. **package.json** - Frontend dependencies
+3. **pyproject.toml** - Backend configuration
+4. **.extensionrc** - CLI-specific settings
+
+### .extensionrc Example
+
+```json
+{
+  "dev": {
+    "port": 9001,
+    "host": "localhost",
+    "autoReload": true
+  },
+  "build": {
+    "mode": "production",
+    "sourceMaps": false,
+    "optimization": true
+  },
+  "test": {
+    "coverage": true,
+    "threshold": {
+      "statements": 80,
+      "branches": 70,
+      "functions": 80,
+      "lines": 80
+    }
+  }
+}
+```
+
+## Templates
+
+### Available Templates
+
+- **basic**: Simple extension with frontend only
+- **full-stack**: Frontend and backend components
+- **sql-panel**: SQL Lab panel extension
+- **api-only**: Backend API extension
+- **chart-plugin**: Custom chart visualization
+
+### Using Templates
+
+```bash
+# Use specific template
+superset-extensions init my-chart --template chart-plugin
+
+# List available templates
+superset-extensions init --list-templates
+```
+
+### Custom Templates
+
+Create custom templates in `~/.superset-extensions/templates/`:
+
+```
+~/.superset-extensions/templates/
+└── my-template/
+    ├── template.json
+    └── files/
+        └── ... template files ...
+```
+
+## Development Workflow
+
+### 1. Create Extension
+
+```bash
+superset-extensions init awesome-feature
+cd awesome-feature
+```
+
+### 2. Install Dependencies
+
+```bash
+# Frontend
+cd frontend && npm install
+
+# Backend (if applicable)
+cd ../backend && pip install -r requirements.txt
+```
+
+### 3. Configure Superset
+
+```python
+# superset_config.py
+ENABLE_EXTENSIONS = True
+LOCAL_EXTENSIONS = [
+    "/path/to/awesome-feature"
+]
+```
+
+### 4. Start Development
+
+```bash
+# Terminal 1: Extension dev server
+superset-extensions dev
+
+# Terminal 2: Superset
+superset run -p 8088 --reload
+```
+
+### 5. Test Changes
+
+Make changes to your code and see them reflected immediately in Superset.
+
+### 6. Build and Package
+
+```bash
+# Validate
+superset-extensions validate
+
+# Test
+superset-extensions test
+
+# Build
+superset-extensions build --mode production
+
+# Bundle
+superset-extensions bundle
+```
+
+### 7. Deploy
+
+Upload the `.supx` file to your Superset instance.
+
+## Environment Variables
+
+The CLI respects these environment variables:
+
+- `SUPERSET_EXTENSIONS_DEV_PORT`: Development server port
+- `SUPERSET_EXTENSIONS_DEV_HOST`: Development server host
+- `SUPERSET_BASE_URL`: Superset instance URL
+- `NODE_ENV`: Node environment (development/production)
+- `PYTHONPATH`: Python module search path
+
+## Troubleshooting
+
+### Common Issues
+
+#### Port Already in Use
+
+```bash
+# Use different port
+superset-extensions dev --port 9002
+```
+
+#### Module Federation Errors
+
+```bash
+# Rebuild with clean cache
+rm -rf dist/ node_modules/.cache
+superset-extensions build
+```
+
+#### Python Import Errors
+
+```bash
+# Ensure virtual environment is activated
+source venv/bin/activate
+superset-extensions dev
+```
+
+### Debug Mode
+
+Enable verbose output for troubleshooting:
+
+```bash
+# Verbose output
+superset-extensions dev --verbose
+
+# Debug webpack
+DEBUG=webpack:* superset-extensions build
+```
+
+## Best Practices
+
+1. **Version Control**: Commit `extension.json` but not `dist/`
+2. **Dependencies**: Pin versions in package.json
+3. **Testing**: Write tests for critical functionality
+4. **Documentation**: Keep README.md updated
+5. **Validation**: Run validate before bundling
+6. **Semantic Versioning**: Follow semver for releases
+
+## Advanced Usage
+
+### Custom Webpack Configuration
+
+Extend the default webpack config:
+
+```javascript
+// webpack.config.js
+const baseConfig = require('./webpack.base.config');
+
+module.exports = {
+  ...baseConfig,
+  // Custom modifications
+  resolve: {
+    ...baseConfig.resolve,
+    alias: {
+      '@': path.resolve(__dirname, 'src'),
+    },
+  },
+};
+```
+
+### CI/CD Integration
+
+```yaml
+# .github/workflows/extension.yml
+name: Extension CI
+
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      - uses: actions/setup-node@v2

+# Getting Started with Extensions
+
+This guide will walk you through creating, developing, and deploying your first Superset extension.
+
+## Prerequisites
+
+Before you begin, make sure you have:
+
+- **Node.js 16+** and npm/yarn installed
+- **Python 3.9+** and pip installed  
+- **Superset** running locally or access to a Superset instance
+- **Git** for version control
+- Basic knowledge of React and TypeScript
+
+## Quick Start
+
+### 1. Install the CLI
+
+First, install the Superset Extensions CLI globally:
+
+```bash
+pip install apache-superset-extensions-cli
+```
+
+### 2. Create Your First Extension
+
+Use the CLI to scaffold a new extension project:
+
+```bash
+superset-extensions init my-first-extension
+cd my-first-extension
+```
+
+This creates the following structure:
+
+```
+my-first-extension/
+├── extension.json          # Extension metadata
+├── frontend/              # Frontend code
+│   ├── src/
+│   │   └── index.tsx     # Main entry point
+│   ├── package.json
+│   └── webpack.config.js
+├── backend/              # Backend code (optional)
+│   ├── src/
+│   └── requirements.txt
+└── README.md
+```
+
+### 3. Configure Your Extension
+
+Edit `extension.json` to define your extension's capabilities:
+
+```json
+{
+  "name": "my-first-extension",
+  "version": "1.0.0",
+  "description": "My first Superset extension",
+  "author": "Your Name",
+  "frontend": {
+    "contributions": {
+      "views": {
+        "sqllab.panels": [
+          {
+            "id": "my-extension.main",
+            "name": "My Panel",
+            "icon": "ToolOutlined"
+          }
+        ]
+      }
+    }
+  }
+}
+```
+
+### 4. Develop Your Extension
+
+Edit `frontend/src/index.tsx` to implement your extension:
+
+```typescript
+import React from 'react';
+import { ExtensionContext } from '@apache-superset/core';
+
+export function activate(context: ExtensionContext) {
+  // Register your panel component
+  const panel = context.core.registerView('my-extension.main', () => (
+    <div style={{ padding: 20 }}>
+      <h2>Hello from My Extension!</h2>
+      <p>This is my first Superset extension.</p>
+    </div>
+  ));
+
+  // Clean up on deactivation
+  context.subscriptions.push(panel);
+}
+
+export function deactivate() {
+  // Cleanup code if needed
+}
+```
+
+### 5. Test Locally
+
+Enable development mode in your Superset configuration:
+
+```python
+# superset_config.py
+ENABLE_EXTENSIONS = True
+LOCAL_EXTENSIONS = [
+    "/path/to/my-first-extension"
+]
+```
+
+Run the development server:
+
+```bash
+# In your extension directory
+superset-extensions dev
+
+# In a separate terminal, start Superset
+superset run -p 8088 --with-threads --reload
+```
+
+Your extension will now appear in SQL Lab!
+
+### 6. Build and Package
+
+When ready to distribute your extension:
+
+```bash
+superset-extensions build
+superset-extensions bundle
+```
+
+This creates a `my-first-extension-1.0.0.supx` file that can be uploaded to any Superset instance.
+
+### 7. Deploy
+
+Upload your extension via the Superset UI or API:
+
+```bash
+curl -X POST http://localhost:8088/api/v1/extensions/import/ \
+  -H "Authorization: Bearer YOUR_TOKEN" \
+  -F "file=@my-first-extension-1.0.0.supx"
+```
+
+## What's Next?
+
+Now that you have a basic extension working, explore:
+
+- [Extension Architecture](../architecture/overview) - Understand how extensions work
+- [API Reference](../api/frontend) - Learn about available APIs
+- [Examples](../examples) - See more complex extension examples
+- [Best Practices](./best-practices) - Learn extension development best practices
+
+## Common Patterns
+
+### Adding a SQL Lab Panel
+
+```typescript
+const panel = context.core.registerView('my-extension.panel', () => (
+  <MyPanelComponent />
+));
+```
+
+### Registering Commands
+
+```typescript
+const command = context.commands.registerCommand('my-extension.run', {
+  title: 'Run My Command',
+  execute: () => {
+    // Command logic
+  }
+});
+```
+
+### Listening to Events
+
+```typescript
+const listener = context.sqlLab.onDidQueryRun((query) => {
+  console.log('Query executed:', query);
+});
+```
+
+### Adding Menu Items
+
+```json
+{
+  "menus": {
+    "sqllab.editor": {
+      "primary": [{
+        "command": "my-extension.run",
+        "when": "editorHasSelection"
+      }]
+    }
+  }
+}
+```
+
+## Troubleshooting
+
+### Extension Not Loading
+
+- Ensure `ENABLE_EXTENSIONS = True` in your config
+- Check the browser console for errors
+- Verify the extension path in `LOCAL_EXTENSIONS`
+
+### Module Not Found Errors
+
+- Run `npm install` in the frontend directory
+- Check that `@apache-superset/core` is properly externalized
+
+### Build Failures
+
+- Ensure all dependencies are installed
+- Check webpack.config.js for proper Module Federation setup
+- Verify extension.json is valid JSON
+

+# Superset Developer Portal
+
+Welcome to the Apache Superset Developer Portal! This is your comprehensive guide to extending and customizing Superset through our new extension architecture.
+
+## What are Superset Extensions?
+
+Superset Extensions provide a powerful way to enhance and customize Apache Superset without modifying the core codebase. Following the successful model pioneered by VS Code, our extension architecture enables developers to:
+
+- **Add custom features** to SQL Lab and other Superset modules
+- **Create reusable components** that can be shared across organizations
+- **Integrate external tools** and services seamlessly
+- **Customize workflows** to match your team's specific needs
+
+## Why Extensions?
+
+As Superset has grown, we've recognized the need for a more modular architecture that allows:
+
+- **Innovation without fragmentation** - Build features without forking the codebase
+- **Community-driven development** - Share and reuse extensions across organizations
+- **Stable APIs** - Develop against versioned, well-documented interfaces
+- **Rapid iteration** - Deploy custom features without waiting for core releases
+
+## Key Features
+
+### 🎯 Well-Defined Extension Points
+
+Extensions can contribute to specific areas of Superset:
+- SQL Lab panels (left, right, bottom, editor)
+- Custom commands and menu items
+- Status bar components
+- API endpoints and backend functionality
+
+### 🔧 Modern Development Experience
+
+- **CLI tools** for scaffolding, building, and packaging
+- **Hot reloading** during development
+- **TypeScript support** with full type safety
+- **Module Federation** for dynamic loading
+
+### 📦 Simple Distribution
+
+- Package extensions as `.supx` files
+- Upload via REST API or UI
+- Automatic activation and lifecycle management
+- Version compatibility checking
+
+## Getting Started
+
+Ready to build your first extension? Check out our [Getting Started Guide](./getting-started) to:
+
+1. Set up your development environment
+2. Create your first extension
+3. Test it locally
+4. Package and deploy it
+
+## Architecture Overview
+
+Our extension architecture is built on several key principles:
+
+- **Lean Core**: Keep Superset's core minimal and delegate features to extensions
+- **Explicit APIs**: Clear, versioned interfaces for extension interactions
+- **Lazy Loading**: Extensions load only when needed for optimal performance
+- **Security First**: Extensions run with appropriate permissions and sandboxing
+
+Learn more in our [Architecture Documentation](./architecture/overview).
+
+## Current Status
+
+The extension architecture is currently in active development. The initial focus is on SQL Lab extensions, with plans to expand to:
+
+- Dashboard extensions
+- Chart plugins (enhanced from current system)
+- Database connectors
+- Security providers
+
+## Example: Dataset References Extension
+
+See the extension system in action with our Dataset References example, which adds a SQL Lab panel showing:
+
+- Tables referenced in queries
+- Table owners for permission requests  
+- Last available partitions
+- Estimated row counts

+You'll need to extend the Superset image to include a headless browser. Your options include:
+- Use Playwright with Chrome: this is the recommended approach as of version >=4.1.x. A working example of a Dockerfile that installs these tools is provided under “Building your own production Docker image” on the [Docker Builds](/docs/installation/docker-builds#building-your-own-production-docker-image) page. Read the code comments there as you'll also need to change a feature flag in your config.
+- Use Firefox: you'll need to install geckodriver and Firefox.
+- Use Chrome without Playwright: you'll need to install Chrome and set the value of `WEBDRIVER_TYPE` to `"chrome"` in your `superset_config.py`.
 
-Note: All the components required (Firefox headless browser, Redis, Postgres db, celery worker and celery beat) are present in the *dev* docker image if you are following [Installing Superset Locally](/docs/installation/docker-compose/).
-All you need to do is add the required config variables described in this guide (See `Detailed Config`).
+In Superset versions <=4.0x, users installed Firefox or Chrome and that was documented here.
 
-If you are running a non-dev docker image, e.g., a stable release like `apache/superset:3.1.0`, that image does not include a headless browser.  Only the `superset_worker` container needs this headless browser to browse to the target chart or dashboard.
-You can either install and configure the headless browser - see "Custom Dockerfile" section below - or when deploying via `docker compose`, modify your `docker-compose.yml` file to use a dev image for the worker container and a stable release image for the `superset_app` container.
-
-*Note*: In this context, a "dev image" is the same application software as its corresponding non-dev image, just bundled with additional tools.  So an image like `3.1.0-dev` is identical to `3.1.0` when it comes to stability, functionality, and running in production.  The actual "in-development" versions of Superset - cutting-edge and unstable - are not tagged with version numbers on Docker Hub and will display version `0.0.0-dev` within the Superset UI.

+
+Superset uses OSM and Mapbox tiles by default. OSM is free but you still need setting your MAPBOX_API_KEY if you want to use mapbox maps.
+
+## Setting map tiles
+
+Map tiles can be set with `DECKGL_BASE_MAP` in your `superset_config.py` or `superset_config_docker.py`
+For adding your own map tiles, you can use the following format.
+
+```python
+DECKGL_BASE_MAP = [
+    ['tile://https://your_personal_url/{z}/{x}/{y}.png', 'MyTile']
+]
+```
+Openstreetmap tiles url can be added without prefix.
+```python
+DECKGL_BASE_MAP = [
+    ['https://c.tile.openstreetmap.org/{z}/{x}/{y}.png', 'OpenStreetMap']
+]
+```
+
+Default values are:
+```python
+DECKGL_BASE_MAP = [
+    ['https://tile.openstreetmap.org/{z}/{x}/{y}.png', 'Streets (OSM)'],
+    ['https://tile.osm.ch/osm-swiss-style/{z}/{x}/{y}.png', 'Topography (OSM)'],
+    ['mapbox://styles/mapbox/streets-v9', 'Streets'],
+    ['mapbox://styles/mapbox/dark-v9', 'Dark'],
+    ['mapbox://styles/mapbox/light-v9', 'Light'],
+    ['mapbox://styles/mapbox/satellite-streets-v9', 'Satellite Streets'],
+    ['mapbox://styles/mapbox/satellite-v9', 'Satellite'],
+    ['mapbox://styles/mapbox/outdoors-v9', 'Outdoors'],
+]
+```
+
+It is possible to set only mapbox by removing osm tiles and other way around.
+
+:::warning
+Setting `DECKGL_BASE_MAP` overwrite default values
+:::
+
+After defining your map tiles, set them in these variables:
+- `CORS_OPTIONS`
+- `connect-src` of `TALISMAN_CONFIG` and `TALISMAN_CONFIG_DEV` variables.
+
+```python
+ENABLE_CORS = True
+CORS_OPTIONS: dict[Any, Any] = {

 Every Antd token works, plus a handful of Superset-specific ones for charts and dashboard chrome.
 
-## 1 — Create a theme
+## Managing Themes via UI
 
-1. Open the official [Ant Design Theme Editor](https://ant.design/theme-editor)
-2. Design your palette, typography, and component overrides.
-3. Open the `CONFIG` modal and paste the JSON.
+Superset includes a built-in **Theme Management** interface accessible from the admin menu under **Settings > Themes**.
+
+### Creating a New Theme
+
+1. Navigate to **Settings > Themes** in the Superset interface
+2. Click **+ Theme** to create a new theme
+3. Use the [Ant Design Theme Editor](https://ant.design/theme-editor) to design your theme:
+   - Design your palette, typography, and component overrides
+   - Open the `CONFIG` modal and copy the JSON configuration
+4. Paste the JSON into the theme definition field in Superset
+5. Give your theme a descriptive name and save
 
 You can also extend with Superset-specific tokens (documented in the default theme object) before you import.
 
-## 2 — Apply it instance-wide
+### System Theme Administration
+
+When `ENABLE_UI_THEME_ADMINISTRATION = True` is configured, administrators can manage system-wide themes directly from the UI:
+
+#### Setting System Themes
+- **System Default Theme**: Click the sun icon on any theme to set it as the system-wide default
+- **System Dark Theme**: Click the moon icon on any theme to set it as the system dark mode theme
+- **Automatic OS Detection**: When both default and dark themes are set, Superset automatically detects and applies the appropriate theme based on OS preferences
+
+#### Managing System Themes
+- System themes are indicated with special badges in the theme list
+- Only administrators with write permissions can modify system theme settings
+- Removing a system theme designation reverts to configuration file defaults
+
+### Applying Themes to Dashboards
+
+Once created, themes can be applied to individual dashboards:
+- Edit any dashboard and select your custom theme from the theme dropdown
+- Each dashboard can have its own theme, allowing for branded or context-specific styling
+
+## Configuration Options
+
+### Python Configuration
+
+Configure theme behavior via `superset_config.py`:
 
 ```python
-# superset_config.py
-THEME = {
-    # Paste your JSON theme definition here
+# Enable UI-based theme administration for admins
+ENABLE_UI_THEME_ADMINISTRATION = True
+
+# Optional: Set initial default themes via configuration
+# These can be overridden via the UI when ENABLE_UI_THEME_ADMINISTRATION = True
+THEME_DEFAULT = {
+    "token": {
+        "colorPrimary": "#2893B3",
+        "colorSuccess": "#5ac189",
+        # ... your theme JSON configuration
+    }
+}
+
+# Optional: Dark theme configuration
+THEME_DARK = {
+    "algorithm": "dark",
+    "token": {
+        "colorPrimary": "#2893B3",
+        # ... your dark theme overrides
+    }
+}
+
+# To force a single theme on all users, set THEME_DARK = None
+# When both themes are defined (via UI or config):
+# - Users can manually switch between themes
+# - OS preference detection is automatically enabled
+```
+
+### Migration from Configuration to UI
+
+When `ENABLE_UI_THEME_ADMINISTRATION = True`:
+
+1. System themes set via the UI take precedence over configuration file settings
+2. The UI shows which themes are currently set as system defaults
+3. Administrators can change system themes without restarting Superset
+4. Configuration file themes serve as fallbacks when no UI themes are set
+
+### Copying Themes Between Systems
+
+To export a theme for use in configuration files or another instance:
+
+1. Navigate to **Settings > Themes** and click the export icon on your desired theme
+2. Extract the JSON configuration from the exported YAML file
+3. Use this JSON in your `superset_config.py` or import it into another Superset instance
+
+## Theme Development Workflow
+
+1. **Design**: Use the [Ant Design Theme Editor](https://ant.design/theme-editor) to iterate on your design
+2. **Test**: Create themes in Superset's CRUD interface for testing
+3. **Apply**: Assign themes to specific dashboards or configure instance-wide
+4. **Iterate**: Modify theme JSON directly in the CRUD interface or re-import from the theme editor
+
+## Custom Fonts
+
+Superset supports custom fonts through runtime configuration, allowing you to use branded or custom typefaces without rebuilding the application.
+
+### Configuring Custom Fonts
+
+Add font URLs to your `superset_config.py`:
+
+```python
+# Load fonts from Google Fonts, Adobe Fonts, or self-hosted sources
+CUSTOM_FONT_URLS = [
+    "https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700&display=swap",
+    "https://fonts.googleapis.com/css2?family=JetBrains+Mono:wght@400;500&display=swap",
+]
+
+# Update CSP to allow font sources
+TALISMAN_CONFIG = {
+    "content_security_policy": {
+        "font-src": ["'self'", "https://fonts.googleapis.com", "https://fonts.gstatic.com"],
+        "style-src": ["'self'", "'unsafe-inline'", "https://fonts.googleapis.com"],
+    }
 }
 ```
 
-Restart Superset to apply changes
+### Using Custom Fonts in Themes
 
-## 3 — Tweak live in the app (beta)
+Once configured, reference the fonts in your theme configuration:
 
-Set the feature flag in your `superset_config`
 ```python
-DEFAULT_FEATURE_FLAGS: dict[str, bool] = {
-    {{ ... }}
-    THEME_ALLOW_THEME_EDITOR_BETA = True,
+THEME_DEFAULT = {
+    "token": {
+        "fontFamily": "Inter, -apple-system, BlinkMacSystemFont, sans-serif",
+        "fontFamilyCode": "JetBrains Mono, Monaco, monospace",
+        # ... other theme tokens
+    }
 }
 ```
 
-- Enables a JSON editor panel inside Superset as a new icon in the navbar
-- Intended for testing/design and rapid in-context iteration
-- End-user theme switching & preferences coming later
+Or in the CRUD interface theme JSON:
 
-## 4 — Potential Next Steps
+```json
+{
+  "token": {
+    "fontFamily": "Inter, -apple-system, BlinkMacSystemFont, sans-serif",
+    "fontFamilyCode": "JetBrains Mono, Monaco, monospace"
+  }
+}
+```
 
-- CRUD UI for managing multiple themes
-- Per-dashboard & per-workspace theme assignment
-- User-selectable theme preferences
+### Font Sources
+
+- **Google Fonts**: Free, CDN-hosted fonts with wide variety
+- **Adobe Fonts**: Premium fonts (requires subscription and kit ID)
+- **Self-hosted**: Place font files in `/static/assets/fonts/` and reference via CSS
+
+This feature works with the stock Docker image - no custom build required!
+
+## Advanced Features
+
+- **System Themes**: Manage system-wide default and dark themes via UI or configuration
+- **Per-Dashboard Theming**: Each dashboard can have its own visual identity
+- **JSON Editor**: Edit theme configurations directly within Superset's interface
+- **Custom Fonts**: Load external fonts via configuration without rebuilding
+- **OS Dark Mode Detection**: Automatically switches themes based on system preferences
+- **Theme Import/Export**: Share themes between instances via YAML files
+
+## API Access
+
+For programmatic theme management, Superset provides REST endpoints:
+
+- `GET /api/v1/theme/` - List all themes
+- `POST /api/v1/theme/` - Create a new theme
+- `PUT /api/v1/theme/{id}` - Update a theme
+- `DELETE /api/v1/theme/{id}` - Delete a theme
+- `PUT /api/v1/theme/{id}/set_system_default` - Set as system default theme (admin only)
+- `PUT /api/v1/theme/{id}/set_system_dark` - Set as system dark theme (admin only)
+- `DELETE /api/v1/theme/unset_system_default` - Remove system default designation
+- `DELETE /api/v1/theme/unset_system_dark` - Remove system dark designation
+- `GET /api/v1/theme/export/` - Export themes as YAML
+- `POST /api/v1/theme/import/` - Import themes from YAML
+
+These endpoints require appropriate permissions and are subject to RBAC controls.

+## GitHub Codespaces (Cloud Development)
+
+GitHub Codespaces provides a complete, pre-configured development environment in the cloud. This is ideal for:
+- Quick contributions without local setup
+- Consistent development environments across team members
+- Working from devices that can't run Docker locally
+- Safe experimentation in isolated environments
+
+:::info
+We're grateful to GitHub for providing this excellent cloud development service that makes
+contributing to Apache Superset more accessible to developers worldwide.
+:::
+
+### Getting Started with Codespaces
+
+1. **Create a Codespace**: Use this pre-configured link that sets up everything you need:
+
+   [**Launch Superset Codespace →**](https://github.com/codespaces/new?skip_quickstart=true&machine=standardLinux32gb&repo=39464018&ref=master&devcontainer_path=.devcontainer%2Fdevcontainer.json&geo=UsWest)
+
+   :::caution
+   **Important**: You must select at least the **4 CPU / 16GB RAM** machine type (pre-selected in the link above).
+   Smaller instances will not have sufficient resources to run Superset effectively.
+   :::
+
+2. **Wait for Setup**: The initial setup takes several minutes. The Codespace will:
+   - Build the development container
+   - Install all dependencies
+   - Start all required services (PostgreSQL, Redis, etc.)
+   - Initialize the database with example data
+
+3. **Access Superset**: Once ready, check the **PORTS** tab in VS Code for port `9001`.
+   Click the globe icon to open Superset in your browser.
+   - Default credentials: `admin` / `admin`
+
+### Key Features
+
+- **Auto-reload**: Both Python and TypeScript files auto-refresh on save
+- **Pre-installed Extensions**: VS Code extensions for Python, TypeScript, and database tools
+- **Multiple Instances**: Run multiple Codespaces for different branches/features
+- **SSH Access**: Connect via terminal using `gh cs ssh` or through the GitHub web UI
+- **VS Code Integration**: Works seamlessly with VS Code desktop app
+
+### Managing Codespaces
+
+- **List active Codespaces**: `gh cs list`
+- **SSH into a Codespace**: `gh cs ssh`
+- **Stop a Codespace**: Via GitHub UI or `gh cs stop`
+- **Delete a Codespace**: Via GitHub UI or `gh cs delete`
+
+### Debugging and Logs
+
+Since Codespaces uses `docker-compose-light.yml`, you can monitor all services:
+
+```bash
+# Stream logs from all services
+docker compose -f docker-compose-light.yml logs -f
+
+# Stream logs from a specific service
+docker compose -f docker-compose-light.yml logs -f superset
+
+# View last 100 lines and follow
+docker compose -f docker-compose-light.yml logs --tail=100 -f
+
+# List all running services
+docker compose -f docker-compose-light.yml ps
+```
+
+:::tip
+Codespaces automatically stop after 30 minutes of inactivity to save resources.
+Your work is preserved and you can restart anytime.

+
+Validate your environment:
+```bash
+curl -f http://localhost:8088/health && echo "✅ Superset ready"

+- Always validate environment setup first using the health checks above
+- Use focused validation commands: `pre-commit run` (not `--all-files`)
+- **Read [LLMS.md](https://github.com/apache/superset/blob/master/LLMS.md) first** - Contains comprehensive development guidelines, coding standards, and critical refactor information
+- **Check platform-specific files** when available:

+  - `CURSOR.md` - For Cursor editor
+  - `GEMINI.md` - For Google Gemini tools
+  - `GPT.md` - For OpenAI/ChatGPT tools
+- Follow the TypeScript migration guidelines and avoid deprecated patterns listed in LLMS.md

+#### Known Issues and Workarounds
+
+**Jest Test Hanging (MessageChannel Issue)**
+
+If Jest tests hang with "Jest did not exit one second after the test run has completed", this is likely due to the MessageChannel issue from rc-overflow (Ant Design v5 components).
+
+**Root Cause**: `rc-overflow@1.4.1` creates MessageChannel handles for responsive overflow detection that remain open after test completion.
+
+**Current Workaround**: MessageChannel is mocked as undefined in `spec/helpers/jsDomWithFetchAPI.ts`, forcing rc-overflow to use requestAnimationFrame fallback.
+
+**To verify if still needed**: Remove the MessageChannel mocking lines and run `npm test -- --shard=4/8`. If tests hang, the workaround is still required.
+
+**Future removal conditions**: This workaround can be removed when:
+- rc-overflow updates to properly clean up MessagePorts in test environments
+- Jest updates to handle MessageChannel/MessagePort cleanup better
+- Ant Design switches away from rc-overflow
+- We switch away from Ant Design v5
+
+**See**: [PR #34871](https://github.com/apache/superset/pull/34871) for full technical details.
