F2p players can still get updates, it's mentioned that this fvn will be free at the end of development, dev logs aren't updated anymore for some reason, so if you want to know what's in the public update, you have to check the patreon monthly reports or read the Update highlights at the top left of the opening screen of the game.
Other than that, you can press "More information" above the download button to check when the game gets updated (not always reliable cause the updated x days ago line counts the page being edited as an update, so might as well also check the game version on the page and in our files.)
