Detail change list in this build, here.
I don't know which build this exists but in this build, when I want to revert a file from Subversion, IDEA will show me a dialog to choose the files I want to revert. It didn't revert only the current file silently.
Keep going with "Deveplop with pleasure" slogan, JetBrains! :-)
Update: IDEA's TestNG plugin still works fine with TestNG 5.0
