 ## [Unreleased]

+## [2.33.2] - 2026-01-13
+
+### Changed
+
+- **Updated n8n dependencies to latest versions**
+  - n8n: 2.2.3 → 2.3.3
+  - n8n-core: 2.2.2 → 2.3.2
+  - n8n-workflow: 2.2.2 → 2.3.2
+  - @n8n/n8n-nodes-langchain: 2.2.2 → 2.3.2
+  - Rebuilt node database with 537 nodes (434 from n8n-nodes-base, 103 from @n8n/n8n-nodes-langchain)
+  - Updated README badge with new n8n version
+
+## [2.33.1] - 2026-01-12
+
+### Fixed
+
+- **Docker image version mismatch bug**: Docker images were built with stale `package.runtime.json` (v2.29.5) while npm package was at v2.33.0
+  - Root cause: `build-docker` job in `release.yml` did not sync `package.runtime.json` version before building
+  - The `publish-npm` job synced the version, but both jobs ran in parallel, so Docker got the stale version
+  - Added "Sync runtime version" step to `release.yml` `build-docker` job
+  - Added "Sync runtime version" step to `docker-build.yml` `build` and `build-railway` jobs
+  - All Docker builds now sync `package.runtime.json` version from `package.json` before building
+
+## [2.33.0] - 2026-01-08
+
+### Added
+
+**AI-Powered Documentation for Community Nodes**
+
+Added AI-generated documentation summaries for 537 community nodes, making them accessible through the MCP `get_node` tool.
+
+**Features:**
+- **README Fetching**: Automatically fetches README content from npm registry for all community nodes
+- **AI Summary Generation**: Uses local LLM (Qwen or compatible) to generate structured documentation summaries
+- **MCP Integration**: AI summaries exposed in `get_node` with `mode='docs'`
+
+**AI Documentation Structure:**
+```json
+{
+  "aiDocumentationSummary": {
+    "purpose": "What this node does",
+    "capabilities": ["key features"],
+    "authentication": "API key, OAuth, etc.",
+    "commonUseCases": ["practical examples"],
+    "limitations": ["known caveats"],
+    "relatedNodes": ["related n8n nodes"]
+  },
+  "aiSummaryGeneratedAt": "2026-01-08T10:45:31.000Z"
+}
+```
+
+**New CLI Commands:**
+```bash
+npm run generate:docs              # Full generation (README + AI summary)
+npm run generate:docs:readme-only  # Only fetch READMEs from npm
+npm run generate:docs:summary-only # Only generate AI summaries
+npm run generate:docs:incremental  # Skip nodes with existing data
+npm run generate:docs:stats        # Show documentation statistics
+npm run migrate:readme-columns     # Migrate database schema
+```
+
+**Environment Variables:**
+```bash
+N8N_MCP_LLM_BASE_URL=http://localhost:1234/v1  # LLM server URL
+N8N_MCP_LLM_MODEL=qwen3-4b-thinking-2507       # Model name
+N8N_MCP_LLM_TIMEOUT=60000                       # Request timeout
+```
+
+**Files Added:**
+- `src/community/documentation-generator.ts` - LLM integration with Zod validation
+- `src/community/documentation-batch-processor.ts` - Batch processing with progress tracking
+- `src/scripts/generate-community-docs.ts` - CLI entry point
+- `src/scripts/migrate-readme-columns.ts` - Database migration script
+
+**Files Modified:**
+- `src/database/schema.sql` - Added `npm_readme`, `ai_documentation_summary`, `ai_summary_generated_at` columns
+- `src/database/node-repository.ts` - Added AI documentation methods and fields
+- `src/community/community-node-fetcher.ts` - Added `fetchPackageWithReadme()` and batch fetching
+- `src/community/index.ts` - Exported new classes
+- `src/mcp/server.ts` - Added AI documentation to `get_node` docs mode response
+
+**Statistics:**
+- 538/547 community nodes have README content
+- 537/547 community nodes have AI-generated summaries
+
+## [2.32.1] - 2026-01-08
+
+### Fixed
+
+- **Community node case sensitivity bug**: Fixed `extractNodeNameFromPackage` to use lowercase node names, matching n8n's community node convention (e.g., `chatwoot` instead of `Chatwoot`). This resolves validation failures for community nodes with incorrect casing.
+- **Case-insensitive node lookup**: Added fallback in `getNode` to handle case differences between stored and requested node types for better robustness.
+

Romuald Członkowski	a9c4400a92	fix: sync package.runtime.json version in Docker builds (v2.33.1) (#534 ) Docker images were built with stale package.runtime.json (v2.29.5) while npm package was at v2.33.0. This was caused by the build-docker job not syncing the version before building, while publish-npm did. Changes: - Add "Sync runtime version" step to release.yml build-docker job - Add "Sync runtime version" step to docker-build.yml build job - Add "Sync runtime version" step to docker-build.yml build-railway job - Bump version to 2.33.1 to trigger release with fix The sync uses a lightweight Node.js one-liner (no npm install needed) to update package.runtime.json version from package.json before Docker builds.
