I have performed two updates dealing mostly with security issues. We changed from 2.0 RC1 to 2.0 RC 1.2.
From the admin panel it looks like everything went smoothly and that previous modifications are still running correctly. My only real concern is that hidden boards may have become visible. If you notice any boards suddenly appearing that weren't there before, or any disappearing that were there yesterday, please PM me.
I know there are several things broken on the forum. So I'm not asking for a bug report. This upgrade is step one to fixing that which is broken (the chat room, gallery, blogs, etc.). I just need to make sure I haven't broken anything new in the process. The only two areas at risk with this upgrade are spam security and board visibility.
