You are right, the link to the update is on the top of the game description page which leads to patreon and subscriberstar. I'll add the links in this post as well.
Thanks! One more question regarding patreon. The description of Patron level says "latest version 1 week after release". But why is 4.5.0 not released to Patron yet? Level ist still set to Crusader.Last Patron post was Dec 23. 4.5.0 is from May 24. Could you lift that confusion as well?
