* fix: deprecate USE_FIXED_HTTP for SSE streaming support (Issue #524) 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.

## [Unreleased]
|
|
|
|
## [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.

|
|
### Added
|
|
|
|
**MCP Tool Annotations (PR #512)**
|
|
|
|
Added MCP tool annotations to all 20 tools following the [MCP specification](https://spec.modelcontextprotocol.io/specification/2025-03-26/server/tools/#annotations). These annotations help AI assistants understand tool behavior and capabilities.
|
|
|
|
**Annotations added:**
|
|
- `title`: Human-readable name for each tool
|
|
- `readOnlyHint`: True for tools that don't modify state (11 tools)
|
|
- `destructiveHint`: True for delete operations (3 tools)
|
|
- `idempotentHint`: True for operations that produce same result when called repeatedly (14 tools)
|
|
- `openWorldHint`: True for tools accessing external n8n API (13 tools)
|
|
|
|
**Documentation tools** (7): All marked `readOnlyHint=true`, `idempotentHint=true`
|
|
- `tools_documentation`, `search_nodes`, `get_node`, `validate_node`, `get_template`, `search_templates`, `validate_workflow`
|
|
|
|
**Management tools** (13): All marked `openWorldHint=true`
|
|
- Read-only: `n8n_get_workflow`, `n8n_list_workflows`, `n8n_validate_workflow`, `n8n_health_check`
|
|
- Idempotent updates: `n8n_update_full_workflow`, `n8n_update_partial_workflow`, `n8n_autofix_workflow`
|
|
- Destructive: `n8n_delete_workflow`, `n8n_executions` (delete action), `n8n_workflow_versions` (delete/truncate)
|
|
|
|
## [2.31.4] - 2026-01-02
|
|
|
|
### Fixed
|
|
|
|
**Workflow Data Mangled During Serialization: snake_case Conversion (Issue #517)**
|
|
|
|
Fixed a critical bug where workflow mutation data was corrupted during serialization to Supabase, making 98.9% of collected workflow data invalid for n8n API operations.
