• Fixed issue where generated libraryfolders.vdf file had garbage memory written to it breaking software relying on it, e.g. mod launchers.

How to get it

All you have to do is ensure you've got Proton Experimental installed by searching for it directly in your Steam Library. Then you can (if you need to) swap over the Proton version on a game by game basis. Valve will automatically pick what's best when games go through Deck Verified (which also applies to Desktop Linux).
