IntelliJ IDEA 11.1 RC4
Today’s RC build is most likely the last one before the final 11.1 release. Besides the issues listed in the release notes, changes worth noting are a new build of SVNKit and a new checkbox under Settings | Appearance allowing to disable the use of mnemonics under Mac OS X (and allowing to use Alt-letter keyboard shortcuts for entering special characters in any context).
Looking forward to your feedback!
