Jemimah has been hard at work while the rest of us have hardly been working, and has put out RC7. So far I have detected no real (ie; visible to me) changes from RC6, apart from the updated Chrome browser. The minor bug in the boot script that caused me some issues with RC6 seems to be fixed - to be fair she put a patch out for RC6 as well, so it ended up being a very, very minor issue anyway.
An definite upside was how it recognised and loaded my save file reasonable seamlessly - just taking a couple of minutes to update the file system. All the add-ons I had under FireFox still works, as do Xchat.
More review when I had time to use it more.
