The most important changes according to the commit messages:

• v1.2.0: Support for HelixSR 3.2.0 with the new HLX DLSS, HLX FSR 4 and HelixSR Scaler methods.
• v1.3.0: New FSR 4.1.2 INT8 Lite method via OptiScaler 10, installable and removable per game. The installation is verified from the logs, and native Linux games are listed as unsupported. The update also fixes DXGI spoofing problems with DX11 and Unity games.
• v1.3.1: The Unity/DX11 OptiScaler fix from v1.3.0 was also ported to the desktop apps (WPF and Flutter). The plugin gets the update because it bundles the Linux engine.
• v1.3.2: The selected Method no longer snaps back to FSR 4 Lite. Steam unmounted the Quick Access panel while a dropdown was open, which lost the selection. Picks are now stored per game folder and take priority over the defaults.
