 # Lumi changelog
 
+## 0.3.1
+
+- Fixed apparently inert Stream Testing starts by surfacing the server rejection immediately in the Stream Testing panel and local diagnostic log.
+- Added bounded Windows FFmpeg discovery for verified WinGet and conventional installations, while preserving explicit `LUMI_FFMPEG_PATH` configuration and Linux PATH behavior.
+- Added explicit loaded/installed/bundled OBS Bridge version comparison, update-required notices and actions on Overview and Connection & device, and blocked Stream Testing until an outdated bridge is updated and loaded.
+
 ## 0.3.0
 
 - Added admin-only private stream testing for the real OBS output with expiring authenticated sessions, supervised FFmpeg ingest, source/720p/480p no-upscale HLS, automatic/manual quality, audio, fullscreen, reused captions, real OBS/receiver diagnostics, bounded cleanup, and a deterministic test pattern.

 # Lumi Transcription changelog
 
+## 0.2.1
+
+- Surface Stream Testing startup failures immediately instead of leaving the Companion action waiting with a stale status.
+- Detect the OBS Bridge version actually loaded by OBS and show Update OBS Bridge actions on Overview and Connection & device when it differs from the bundled integration.
+- Prevent private output redirection until an outdated or damaged OBS integration is updated or repaired.
+
 ## 0.2.0
 
 - Added authenticated private stream-test session control over the existing Companion transport, including reused live caption cues and OBS output diagnostics.
