Upstream releases

Release notes supplied by the developer. These dates are not Flathub package publication times.

2.5.0-115 Oct 2026
  • Added an option to enable interface navigation sounds. Users can choose from the provided samples or use their own audio files and control the volume.
  • Reworked the Prevent Sleep option. Now it should work on more systems. The python-dbus dependency was removed because it's no longer needed.
  • Improved banner transition performance. With this change, scrolling through games in Carousel mode should feel smoother when banners are displayed.
  • Now the Proton Manager also handles the "Latest" options.
  • Added an option to remove the icons/covers/banners. Thanks @Alexlee500
  • Now if a launcher installation fails, the prefix is kept if it's shared with other games/apps.
  • Added Ubuntu 26.10 PPA build.
  • Fixed Proton Manager showing versions that haven't been downloaded as if they had been.
  • Fixed a bug that caused Grid icons and the shortcut icon button to become larger on older GTK versions.
  • Fixed icons from launchers not being fetched from SteamGridDB on List/Grid modes.
  • Updated translations.
