+* BREAKING CHANGE: (bug 44385) Removed the jquery.collapsibleTabs module and
+ moved it to the Vector extension. It was entirely Vector-extension-specific,
+ deeply interconnected with the extension, and this functionality really
+ belongs to the extension instead of the skin anyway. In the unlikely case you
+ were using it, you have to either copy it to your extension, or install the
+ Vector extension (and possibly disable its features using config settings if
+ you don't want them).
