What's New
Introduces isolated server processes for SSE and WebSocket to prevent state sharing.
Breaking Changes
- Clients no longer share server state across SSE and WebSocket connections.
- A client that reconnects now gets a fresh server process.
New Features
- Added `--sessionTimeout` flag to manage idle sessions.
- Support for JSON-RPC batches and per-server protocol versions.
- Request bodies up to 4 MB are now supported in Streamable HTTP modes.
- Relay server-initiated requests, notifications, and cancellation through WebSocket.
Improvements
- Slow clients can no longer exhaust the gateway's memory.
- Malformed or oversized POST requests no longer end SSE sessions.
- Escape U+2028/U+2029 in SSE JSON to prevent message splitting.
- Keep idle HTTP connections for 65 seconds to avoid 502s.
Bug Fixes
- Malformed or oversized POST requests no longer end SSE sessions.
Upgrade Notes
Clients relying on shared server state across SSE and WebSocket connections will experience a break; review your code. Use the new `--sessionTimeout` flag to manage idle sessions and proxies effectively.
