[0.9.0] - 2026-04-25

This is a pretty big release, with major UI changes and a long-awaited feature for Nvidia users.
Primary changes:

• UI Update (#951, #972, #975 and others)

  The UI has been reworked with a new layout and lots of styling changes. Overall, it should be much nicer to look at and use, without sacrificing information density.

  

  An important technical change is that LACT now utilizes libadwaita, rather than plain GTK4. The focus in GTK development over recent years has been almost entirely on libadwaita, and this decision allows LACT to make use of various new widgets, layouts and other improvements from the ecosystem.

  For the KDE users who are worried about the application looking out of place with the rest of the system, there is an in-app Breeze theme option that will be enabled automatically if Breeze is your system theme. It should in fact look better than before, as the global breeze-gtk theme often did not work well with GTK4 and caused elements to be missized or have missing icons.

• Nvidia Voltage-Frequency Curve Editor (#957)

  While previously considered not to be available on Linux, LACT now has a VF curve editor for Nvidia GPUs that allows for more precise tweaking in a similar manner to Windows tools such as MSI Afterburner.

  An very important note is that this editor relies on entirely undocumented driver functionality, and as such there are zero guarantees regarding its stability or safety. There haven't been any issues discovered during testing and the behaviour has been cross-compared with known Windows tools. But nothing stops Nvidia from removing it in a future driver version for example.

  I also want to express my thanks to @Ristovski, who has helped with the reverse engineering efforts to get this feature working.

  

• Nvidia target temperature setting (#917)

  Also known as acoustic target, this option allows you to set the target temperature that the card will try to maintain, without needing to use an entirely custom fan curve.

• AMD Hardware blocks information reporting (#942)

  You can now see which hardware IP blocks your AMD GPU has.
  For example, this can be useful to check which hardware encoder (VCN) generation you have.

• More AMD hardware quirks

  • Voltage settings are now applied properly on some specific Vega cards (#974)
  • Custom clock settings now work on Phoenix iGPUs (#948)

• Better Flatpak service reliability (#902 and a few others)

  This makes the host service that's installed by the Flatpak version work more reliably across different setups.
  One notable case is that this resolves permissions errors with Nvidia GPUs on systems with AppArmor (most Ubuntu-based distributions)

Packaging info

Notable dependencies on this version:

• Rust 1.93+
• libadwaita 1.5+
• GTK 4.14+

Due to the increase in the minimum GTK version requirement, packages for Ubuntu 22.04 and Debian 12 have been dropped.
