Release Notes

v0.2.1

This update focuses on recording correctness, session lifecycle cleanup, better observability, Douyu compatibility updates, and frontend stability improvements. It also includes a broad round of dependency and CI maintenance.

Highlights

• Added split reason tracking across the full stack
  Segment split reasons are now modeled and surfaced consistently across FLV/HLS pipelines, backend events, API responses, database session data, WebSocket/protobuf messages, and the frontend session details UI.

• Improved session lifecycle correctness

  • Active sessions now close when disabled streamers are later confirmed offline
  • Temporary-disabled backoff handling is now authoritative and no longer bypassed by live events
  • Cancellation is treated as successful completion instead of a failure state

• Improved Douyu support

  • Updated Douyu API handling for new request/version requirements and newer error-code behavior
  • Region-lock and retry-related error handling was adjusted accordingly

• Added and exposed danmu statistics
  Danmu statistics are now collected, exposed by the backend, and displayed in the session UI.

• Improved frontend stability and polish

  • Fixed FOUC/theme initialization issues
  • Standardized dashboard loading skeletons and animations
  • Improved session playback UX and related frontend behavior

• Improved notification quality

  • Download notifications now use the streamer display name instead of UUIDs
  • Telegram HTML payload handling was fixed
  • Legacy web push AES128GCM header handling was cleaned up

Behavior changes / review before upgrading

• Douyu HS CDN support was removed
  If you relied on that specific Douyu configuration path, review your setup after upgrading.

• Split reason data model changed
  This update adds richer segment/session split metadata and includes a related database migration. Review any consumers that depend on previous session or segment semantics.

• HLS configuration was cleaned up
  Mesio HLS configuration was reorganized across backend and frontend forms/schema. Review HLS-related settings after upgrading.

• Cancellation semantics changed
  Cancellation is now treated as a successful completion path rather than a failure outcome. If you rely on completion/failure status downstream, review that behavior.

• Temporary-disabled streamer behavior changed
  Backoff and disabled_until handling now remain authoritative even when new live events arrive.

• Disabled streamers now close active sessions once offline is confirmed
  This may affect operational expectations if you previously relied on lingering sessions.
