Release Date: August 2026

### Faster, More Reliable Device Switching

- Keeps input and output lists current while devices connect, disconnect, or transition between modes—including Bluetooth devices

- Prevents rapid source changes from bouncing back to a previously selected device

- When Auto-Select is enabled, pressing an Input Source, Output Source, or Unified Source dial now cycles to the next device

- Keeps Unified Source dials in sync immediately after a switch

### Expanded Apollo Support

- Automatically discovers the correct monitor output across more Universal Audio Apollo models, including Apollo x16 configurations

- Improves Apollo volume and mute response handling and recovery after UA Console connection interruptions

### Stability and Compatibility

- Keeps the audio helper responsive when macOS CoreAudio is slow or stalled during startup

- Uses live device-list updates to reduce delays during audio-device transitions

- Fixes volume changes on devices that do not report a standard output-mute value

- Improves compatibility with protected Elgato Marketplace installations

- Adds clearer diagnostics for startup, device switching, and Apollo discovery issues
