After we released IntelliJ IDEA 11.1, a critical bug was discovered in the SVNKit library, which could lead to changes being committed to the wrong branch after you switched your working copy to a different branch. We’d like to make the fix available to our users as soon as possible, and we’re doing this today by releasing the IntelliJ IDEA 11.1.1 bugfix update (build 117.117). In addition to the SVNKit fix, it also fixes a problem which caused plugins to get stuck in the “Downloaded” state without any possibility to install them, and a number of other minor issues.
If you’re already running IntelliJ IDEA 11.1, you can upgrade to the new build using the “Check for updates” action. Otherwise, please download the complete installer.
