Bug-fix release. Small performance improvements too. The only visible change would be the fact that the config option "updateIcon" is now "false" by default - i.e. you have to explicitly tell which windows you would like to update their icons in the Application Tabs Widget (the only such one I personally use is the Windows Explorer).
This is the 64-bit version of the release. Be sure to use that if you are on a 64-bit Windows. Works with "Required DLLs v3".
