fix: memory leak in SSE session reset (#542 )

When SSE sessions are recreated every 5 minutes, the old session's MCP server was not being closed, causing: - SimpleCache cleanup timer continuing to run indefinitely - Database connections remaining open - Cached data (~50-100MB per session) persisting in memory Added server.close() call before transport.close() in resetSessionSSE(), mirroring the existing cleanup pattern in removeSession().

 ## [Unreleased]
 ## [2.33.4] - 2026-01-21
 ### Fixed
 - **Memory leak in SSE session reset** (Issue #542): Fixed memory leak when SSE sessions are recreated every 5 minutes
  - Root cause: `resetSessionSSE()` only closed the transport but not the MCP server
  - This left the SimpleCache cleanup timer (60-second interval) running indefinitely
  - Database connections and cached data (~50-100MB per session) persisted in memory
  - Fix: Added `server.close()` call before `transport.close()`, mirroring the existing cleanup pattern in `removeSession()`
  - Impact: Prevents ~288 leaked server instances per day in long-running HTTP deployments
 ## [2.33.3] - 2026-01-21
 ### Changed
 - **Updated n8n dependencies to latest versions**
  - n8n: 2.3.3 → 2.4.4
  - n8n-core: 2.3.2 → 2.4.2
  - n8n-workflow: 2.3.2 → 2.4.2
  - @n8n/n8n-nodes-langchain: 2.3.2 → 2.4.3
 ### Added

  - Added type structure definition in `src/constants/type-structures.ts`
  - Updated type count from 22 to 23 NodePropertyTypes
  - Updated related tests to reflect the new type
 ### Fixed
 - Rebuilt node database with 803 nodes (541 from n8n-nodes-base, 262 from @n8n/n8n-nodes-langchain)
 ## [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

 ## [2.32.1] - 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.
+- **Fixed community node count discrepancy**: The search tool now correctly returns all 547 community nodes
- **Case-insensitive node lookup**: Added fallback in `getNode` to handle case differences between stored and requested node types for better robustness.
+  - Root cause: `countCommunityNodes()` method was not counting nodes with NULL `is_community` flag
  - Added query to count nodes where `source_package NOT IN ('n8n-nodes-base', '@n8n/n8n-nodes-langchain')`
  - This includes nodes that may have been inserted without the `is_community` flag set

+## [2.32.0] - 2026-01-08
 ### Added
-**Community Nodes Support (Issues #23, #490)**
+- **Community Node Search Integration**: Added `source` filter to `search_nodes` tool
  - Filter by `"core"` for official n8n nodes (n8n-nodes-base + langchain)
  - Filter by `"community"` for verified community integrations
  - Filter by `"all"` (default) for all nodes
  - Example: `search_nodes({ query: "google", source: "community" })`
-Added comprehensive support for n8n community nodes, expanding the node database from 537 core nodes to 1,084 total nodes (537 core + 547 community).
+- **Community Node Statistics**: Added community node counts to search results
-
+  - Shows `communityNodeCount` in search results when searching all sources
-**New Features:**
+  - Indicates how many results come from verified community packages
 - **547 community nodes** indexed (301 verified + 246 popular npm packages)
 - **`source` filter** for `search_nodes`: Filter by `all`, `core`, `community`, or `verified`
 - **Community metadata** in search results: `isCommunity`, `isVerified`, `authorName`, `npmDownloads`
 - **Full schema support** for verified community nodes (no additional parsing needed)
 **Data Sources:**
 - Verified nodes fetched from n8n Strapi API (`api.n8n.io/api/community-nodes`)
 - Popular npm packages from npm registry (keyword: `n8n-community-node-package`)
 **New CLI Commands:**
 ```bash
 npm run fetch:community              # Full rebuild (verified + top 100 npm)
 npm run fetch:community:verified     # Verified nodes only (fast)
 npm run fetch:community:update       # Incremental update (skip existing)
 ```
 **Example Usage:**
 ```javascript
 // Search only community nodes
 search_nodes({query: "scraping", source: "community"})
 // Search verified community nodes
 search_nodes({query: "pdf", source: "verified"})
 // Results include community metadata
 {
  nodeType: "n8n-nodes-brightdata.brightData",
  displayName: "BrightData",
  isCommunity: true,
  isVerified: true,
  authorName: "brightdata.com",
  npmDownloads: 1234
 }
 ```
 **Files Added:**
 - `src/community/community-node-service.ts` - Business logic for syncing community nodes
 - `src/community/community-node-fetcher.ts` - API integration for Strapi and npm
 - `src/scripts/fetch-community-nodes.ts` - CLI script for fetching community nodes
 **Files Modified:**
 - `src/database/schema.sql` - Added community columns and indexes
 - `src/database/node-repository.ts` - Extended for community node fields
 - `src/mcp/tools.ts` - Added `source` parameter to `search_nodes`
 - `src/mcp/server.ts` - Added source filtering and community metadata to results
 - `src/mcp/tool-docs/discovery/search-nodes.ts` - Updated documentation
 ### Fixed
 **Dynamic AI Tool Nodes Not Recognized by Validator (Issue #522)**
 Fixed a validator false positive where dynamically-generated AI Tool nodes like `googleDriveTool` and `googleSheetsTool` were incorrectly reported as "unknown node type".
 **Root Cause:** n8n creates Tool variants at runtime when ANY node is connected to an AI Agent's tool slot (e.g., `googleDrive` → `googleDriveTool`). These dynamic nodes don't exist in npm packages, so the MCP database couldn't discover them during rebuild.
 **Solution:** Added validation-time inference that checks if the base node exists when a `*Tool` node type is not found. If the base node exists, the Tool variant is treated as valid with an informative warning.
 **Changes:**
 - `workflow-validator.ts`: Added inference logic for dynamic Tool variants
 - `node-similarity-service.ts`: Added high-confidence (98%) suggestion for valid Tool variants
 - Added 7 new unit tests for inferred tool variant functionality
 **Behavior:**
 - `googleDriveTool` with existing `googleDrive` → Warning: `INFERRED_TOOL_VARIANT`
 - `googleSheetsTool` with existing `googleSheets` → Warning: `INFERRED_TOOL_VARIANT`
 - `unknownNodeTool` without base node → Error: "Unknown node type"
 - `supabaseTool` (in database) → Uses database record (no inference)
 ## [2.31.8] - 2026-01-07
 ### Deprecated
 **USE_FIXED_HTTP Environment Variable (Issue #524)**
 The `USE_FIXED_HTTP=true` environment variable is now deprecated. The fixed HTTP implementation does not support SSE (Server-Sent Events) streaming required by clients like OpenAI Codex.
 **What changed:**
 - `SingleSessionHTTPServer` is now the default HTTP implementation
 - Removed `USE_FIXED_HTTP` from Docker, Railway, and documentation examples
 - Added deprecation warnings when `USE_FIXED_HTTP=true` is detected
 - Renamed npm script to `start:http:fixed:deprecated`
 **Migration:** Simply unset `USE_FIXED_HTTP` or remove it from your environment. The `SingleSessionHTTPServer` supports both JSON-RPC and SSE streaming automatically.
 **Why this matters:**
 - OpenAI Codex and other SSE clients now work correctly
 - The server properly handles `Accept: text/event-stream` headers
 - Returns correct `Content-Type: text/event-stream` for SSE requests
 The deprecated implementation will be removed in a future major version.

czlonkowski	f5088918aa	fix: memory leak in SSE session reset (#542 ) When SSE sessions are recreated every 5 minutes, the old session's MCP server was not being closed, causing: - SimpleCache cleanup timer continuing to run indefinitely - Database connections remaining open - Cached data (~50-100MB per session) persisting in memory Added server.close() call before transport.close() in resetSessionSSE(), mirroring the existing cleanup pattern in removeSession().
