Lutris 0.5.18 on Steam OS not available

When opening Lutris in Desktop mode on the Steam Deck, I’m getting the message that ‘Lutris 0.5.17 is no longer supported. Download 0.5.18 here’.

When I go to the Discover store, Lutris is still at version 0.5.17.

How do I get the current, supported version?

You can wait for the package to be updated in Discover, or you could try installing the latest version manually from Lutris’ website or GitHub page.
