Two bugs I reported are fixed (http://www.jetbrains.net/jira/browse/IDEADEV-6870?rc=1 and http://www.jetbrains.net/jira/browse/IDEADEV-6861?rc=1). I will check the big bug later.
Update: They fixed big bug in a clever way: Removes capability to detach library directly from module's root :-D
Update: This build has a better performance but it has some terrible errors, they relate with Ant build and Perforce plugin.
Update: In this build, Unused symbol inspection doesn't work. Resolved: They changed from unused symbol inspection to UnusedDeclaration inspection.
Update: A request for new feature - http://www.jetbrains.net/jira/browse/IDEA-8213
