What's New in v0.16.1

v0.16.1 fixes SSE connection stability for the external annotations API introduced in v0.16.0. 1 PR from an external contributor, 1 first-timer.

SSE Stream Idle Timeout Fix

Bun's default idle timeout of 10 seconds was killing the external annotations SSE stream (/api/external-annotations/stream) before the first 30-second heartbeat could fire. The browser's EventSource auto-reconnected, but each reconnect triggered a full snapshot resend and produced a [Bun.serve]: request timed out after 10 seconds warning in the console.

The fix uses Bun's per-request server.timeout(req, 0) to disable the idle timeout only on SSE stream requests. Normal HTTP requests keep the default 10-second safety net. The change applies to all three server types (plan, review, annotate).

What's Changed

• fix(server): keep external annotation SSE streams alive by @foxytanuki in #439

New Contributors

• @foxytanuki made their first contribution in #439

Community

@foxytanuki filed #438 with a thorough root cause analysis identifying the mismatch between Bun's 10-second idle timeout and the 30-second heartbeat interval, then followed up with the fix in #439.

@j-huang-rj independently identified the same issue and submitted a fix in #433. The targeted per-request approach from #439 was chosen, but both contributors spotted the problem within hours of v0.16.0 shipping.
