Hey,
A few critical patches in this one, run the update.php
I had stopped manually doing patches, and replaced it with a build script (automatically checking versions, patching files, and just using test-cases), leaving bugs in there for the last update. There were a few database changes as well, so this was not completely checked in the auto build. The first releases were tight in how they handled data, but now with all your feedback, that needs to be loosened a bit, so it's just going through growing pains...
Stay tuned this week and next since I'm issuing patches fairly quickly with bug fixes as soon as I find them. There's going to be quite a bit more Q&A from now on.
Sorry about all this trouble.
