+## What's new
+Sandbox HTTP proxying, terminal reliability, and auth robustness improvements.
+
+### Proxy
+- Fixed redirect loops for apps served inside sandboxes (Python HTTP server, Jupyter, etc.)
+- Proxy traffic no longer interferes with terminal and exec connections
+- Services that take a moment to start up inside a sandbox are now retried instead of immediately failing
+
+### Terminal (PTY)
+- Terminal input is no longer blocked by slow network conditions — fast typing no longer causes timeouts or disconnects
+- Input bursts are coalesced into fewer round trips — lower latency under fast typing
+
+### Authentication
+- WebSocket connections now authenticate correctly for both SDK clients (header-based) and browser clients (message-based)
+
+### Bug Fixes
+- Fixed crash in envd when a process exits without a PTY
+- Fixed goroutine leak on sandbox pause
+
+### Others
+- Version bump
