I am guessing that there was more bugs than expected last weekend. Do you have a revised timeline you could give us now?
Sorry about that! I spent the whole weekend working on it, but it's still not quite ready. Right now, I know of three last things I need to fix, which will definitely be done this evening. Fingers crossed I don't find anything else.
Update: I have to go to sleep now for work tomorrow, but it's looking just about ready to be released. I'll do that tomorrow evening after one final test run.
