Check the devlog I just posted. All the changes are listed there. Long story short though, I tried to make a very small change first without doing a new version number and that resulted in some new people playing the game and...finding a few more small bugs that needed to be patched. So I updated AGAIN, with a new version number, and took the opportunity to tweak some small things I'd been meaning to for a while anyway. There's no new content or HUGE bug fixes though, just small stuff.
