This is a big release, adding several new major features:

• Nvidia support! LACT now works with Nvidia GPUs for all of the core functionality (monitoring, clocks configuration, power limits and fan control). It uses the NVML library, so unlike the Nvidia control panel it doesn’t rely on X11 extensions and works under Wayland.
• Multiple profiles for configuration. Currently it is not possible to switch them automatically, but they are configurable through the UI or the unix socket.
• Clocks configuration now works on AMD IGPUs (at least RDNA2). Previously it was not parsed properly due to lack of VRAM settings.
• Zero RPM mode settings on RDNA3. Currently this needs a linux-next to be used, and the functionality is expected to land in kernel 6.13. But this resolves a long-standing issue with RDNA3 that made the fan always disabled below a certain temperature, even if using a custom curve.

There are many other improvements as well, such as better looking and more efficient plots rendering in the historical charts window (thanks to @In-line ) and a Fedora COPR repository providing LACT packages (currently in testing).
