OBS Studio 21.0.1 changelog:

21.0.1 Hotfix

Fixed a crash with the stinger transition.
Fixed a bug where Hauppauge and Live Gamer Portable devices were not outputting audio/video.
Fixed a lock on startup that could occur depending on how audio ducking was configured.

Other General Changes and Fixes

Added a new program theme: Acri.
Changed the default program theme to dark mode for new users.
Changed the text of "Multi-adapter Compatibility" in game capture to "SLI/Crossfire Capture Mode (Slow)". This was changed because the wording "Multi-adapter Compatibility" was a bit vague, and users are not typically aware of the potential performance impact when using the option.
Optimized the preview pane and reduced GPU usage by 2-8% depending on how many sources were in the preview.
The streaming/recording buttons in the main window now highlight while streaming/recording.
Fixed a bug on Windows where desktop audio capture could go slightly out of sync with display/game/window capture on certain audio devices
Fixed an issue where certain Elgato devices would not output audio by default, and would require users to select the audio device manually.
Fixed a bug with studio mode where scenes that are set to fully duplicate would not retain their filters.
Fixed a stuttering bug on Linux with audio monitoring
Fixed MP3 audio support in the browser source on macOS
Fixed a few Dark/Rachni theme issues [full release notes]
