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.

* fix: use lowercase for community node names to match n8n convention
Community nodes in n8n use lowercase node class names (e.g., chatwoot

capitalizing node names, causing validation failures.
Changes:

- Add case-insensitive fallback in getNode for robustness
- Update tests to expect lowercase node names
- Bump version to 2.32.1

* feat: add community nodes support (Issues #23, #490)
Add comprehensive support for n8n community nodes, expanding the node
database from 537 core nodes to 1,084 total (537 core + 547 community).
New Features:
- 547 community nodes indexed (301 verified + 246 npm packages)
- `source` filter for search_nodes: all, core, community, verified
- Community metadata: isCommunity, isVerified, authorName, npmDownloads
- Full schema support for verified nodes (no parsing needed)
Data Sources:
- Verified nodes from n8n Strapi API (api.n8n.io)
- Popular npm packages (keyword: n8n-community-node-package)

check if the base node exists. If yes, treat as valid with warning.

The fixed HTTP implementation does not support SSE streaming required
by clients like OpenAI Codex. This commit deprecates USE_FIXED_HTTP
and makes SingleSessionHTTPServer the default.
Changes:
- Add deprecation warnings in src/mcp/index.ts and src/http-server.ts
- Remove USE_FIXED_HTTP from docker-compose.yml and Dockerfile.railway
- Update .env.example with deprecation notice
- Rename npm script to start:http:fixed:deprecated
- Update all documentation to remove USE_FIXED_HTTP references
- Mark test case as deprecated
Users should unset USE_FIXED_HTTP to use the modern SingleSessionHTTPServer
which supports both JSON-RPC and SSE streaming.

Fixed a critical bug where workflow mutation data was corrupted during
serialization to Supabase. The recursive toSnakeCase() function was
converting nested workflow data, mangling:
- Connection keys (node names like "Webhook" → "_webhook")
- Node field names (typeVersion → type_version)
Solution: Replace recursive conversion with selective mutationToSupabaseFormat()
that only converts top-level field names to snake_case while preserving
nested workflow data exactly as-is.
Impact:
- 98.9% of workflow mutations had corrupted data
- Deployability rate improved from ~21% to ~68%
Changes:
- src/telemetry/batch-processor.ts: New selective converter
- tests/unit/telemetry/batch-processor.test.ts: 3 new regression tests

* fix: n8n_test_workflow webhookId resolution and form handling (v2.28.2)
## Bug Fixes
- **webhookId Resolution**: Fixed trigger handlers using `node.id` instead of
`node.webhookId` for building webhook URLs. This caused 404 errors when
nodes had custom IDs.
- **Chat Trigger URL**: Fixed chat triggers using wrong URL pattern. Now
correctly uses `/webhook/<webhookId>/chat` endpoint.
- **Form Content-Type**: Fixed form triggers failing with "Expected
multipart/form-data" error by switching to proper multipart encoding.
## Enhancements
- **Form Field Types**: Added support for all n8n form field types (text,
textarea, email, number, password, date, dropdown, checkbox, file, hidden)
- **Checkbox Arrays**: Automatically converts arrays to `field[]` format
- **Helpful Warnings**: Reports missing required fields with names and labels
- **Error Hints**: Provides complete field structure on failure

* fix: pin MCP SDK and Zod versions to prevent Zod v4 resolution
Fixes#440, #444, #446, #447, #450
Root cause: package.json declared `"@modelcontextprotocol/sdk": "^1.20.1"`
which allowed npm to resolve to SDK 1.23.0. That version accepts
`"zod": "^3.25 || ^4.0"`, causing npm to deduplicate to Zod v4.
SDK 1.23.0's `isZ4Schema()` function crashes when called with undefined,
which happens for plain JSON Schema objects.
Changes:
- Pin SDK to exact version 1.20.1 (removes ^ prefix)
- Pin Zod to exact version 3.24.1 (removes ^ prefix)
- Add CI workflow to verify fresh installs get compatible versions
The new CI workflow:
- Packs and installs package fresh (without lockfile)
- Verifies SDK is exactly 1.20.1
- Verifies Zod is NOT v4 (blocks 4.x.x)
- Runs weekly to catch upstream dependency changes
