 * Release branches: release branches of the extension are compatible with matching branches of core, e.g. sites using MediaWiki need to use the  branch of the extension. (For extensions hosted on gerrit, these branches are automatically created when new versions of MediaWiki are released.) This results in cleaner code and faster development but users on old core versions do not benefit from bugfixes and new features unless they are backported manually.
