Pretend I didn't post this:
There's stuff up there now, but it's just the release. So, you can run the updater if you feel like it, but nothing new is available yet.
You can update from the old versions now, but I and a few others encountered a few issues. How to kill:
1) Delete updatercurrent.xml and version.dat from your PlaneShift folder.
2) Before updating, select "Skip Updater Version Check" in the options, and click ok.
I'm updating an old install right now, and it seems to be going well. If you don't do the above it kills the updater. Just download and extract the updater zip as outlined in the stickies, and start over.
Note, however, that if you have an old install it's probably better to just go get the new package. It'll be less trouble, and about the same download size.
Edited to add:
Doing the above seems to work, but then it loads up and dies in a half second. It's just borked like it's never been borked before. Um... don't try it.
