You should be able to find the patch notes in "View History" (when you right-click on the game icon in Impulse). At the moment there's a thank you note and troubleshooting instructions... Someone mixed the Readme.txt file to where the patch notes should be... There's a lot of attention to Demigod already. Frogboy had been writing daily status reports. Someone should take that as a cue to add the patch notes to where they belong.

Err... of course if that implies getting a nervous breakdown in the midst of all the other work, nevermind what I just said (this was a "don't shoot the messenger" or "we know that already, you moron" disclaimer).
