[0.8.2] - 2025-10-18

Main changes:

• OpenTelemetry metrics exporter

  The daemon now supports exporting GPU metrics to an OpenTelemetry-compatible server.
  This is primarly useful for server setups, when you want to have a history of GPU usage over time.

  See the docs for how to enable it.

  

• CLI additions

  The previously very basic CLI now has more functionality. New commands:

  • lact profile for managing settings profiles, such as setting the current profile or toggling automatic switching
  • lact power-limit for power cap configuration
  • lact stats for GPU monitoring

• UX Improvements

  • On a multi-GPU system, the UI will now default to selecting the first detected dGPU (previously the iGPU was often the default option)
  • Historical charts now show the average stat value (hidden behind the info button)
  • Historical charts are now more responsive to input (such as resizing the window or editing stats)
  • It is now possible to change the stats polling rate in the UI for reduced resource usage
  • Dynamic numbers in the UI now use mono fonts to avoid the text sliding around (it was noticeable with the new default Gnome font)

• Flatpak improvements

  • The UI will now use a dark theme based on system preference (See #585 for more info - the lack of full theming support is a flatpak limitation in GTK4 apps)
  • Automatic profile switching based on gamemode being active now works in flatpak
  • Flatpak build bundles are now included in GitHub releases

• Various translation updates

  Thanks to community contributions on Weblate, LACT is now fully localized in German, French, Czech, Portuguese, Chinese and Arabic (barring RTL language issues), as well as several other languages that are partially translated.

• Intel Battlemage power limit setting fix
