## Fixed
<!-- Bug fixes -->
- Fix `concurrent map read and map write` runtime fatal in `linuxSystemTray` when the tray menu is updated while the panel reads it.
- Use `log` instead of `fmt` for WebView2 error and stack trace output so messages aren't lost when the app runs without an attached console on Windows.

## Deprecated
<!-- Soon-to-be removed features -->
