Shutdown update
- Fixed a problem that would prevent Critter shutting down correctly causing it to linger as a ghost process
Changelog
What changed in Critter Connect 2.
Supporter improvements, updater polish, core maintenance, and the stream-side tools that have shaped the app over time.
Supporter update
- Added supporter key validation backed by the Critter website so supporter features can be unlocked directly in the app.
- Improved the Settings and About pages to surface supporter status, license details, and support code information more clearly.
- Cleaned up version handling, installer flow, and release presentation for the 2.9.0 rollout.
Stability update
- Modernized Twitch support to newer TwitchLib packages and switched EventSub handling to the maintained websocket client.
- Fixed Twitch auth, token refresh, and channel setup flow so EventSub and chat use the latest saved credentials.
- Reduced Twitch timeout and reconnect issues by blocking duplicate auth, chat, and websocket startup attempts.
- Improved bot and broadcaster chat handling so connections can be recreated cleanly without stale state.
- Cleaned up nullable and config model defaults so missing values fail more safely instead of causing random null issues.
- Improved app shutdown so Twitch, SignalR, UDP, speech-to-text, and TTS stop more cleanly.
- Hardened OpenAI and config handling with clearer fallback behavior when keys, models, or saved values are missing.
- General maintenance cleanup across Twitch, MVVM base classes, and startup/shutdown flow.
