Kiro 2.19.1

2.19.1 Aug 21, 2026 Spec Review Mouse Support and Automatic Stream Recovery This release brings mouse support to the spec review screen. Under the hood, a stream idle watchdog, automatic retries with backoff, and a 60-minute streaming timeout mean a dropped connection or a throttled request no longer hangs or ends your turn. Mouse support in spec review The spec review screen now supports the mouse: scroll to navigate the document and click to position the cursor. Press m to toggle mouse support on or off. Learn more -> Automatic recovery from stream and network failures Turns no longer hang on a stalled response stream: an idle watchdog warns after 60 seconds of silence and cancels at 300, while throttling, 5xx errors, and connection drops are retried automatically with backoff. Streaming responses also get a 60-minute timeout by default, so long responses are no longer cut off. Tune all of it with the api.streamIdleSoftTimeout , api.streamIdleHardTimeout , and api.timeout settings.
