Beside the elder Patroller extension for patrolling recent changes and new pages, there is a highly configurable MediaWiki extension, called FlaggedRevs.
FlaggedRevs – being already enabled on several Wikimedia wikis – is a toolset for transparent and ensured article patrolling and/or for reliable quality assurance by specifying certain accurate article revisions that are shown to the public by default. Those stable article versions are identified in a release process by a trustable editorial staff and/or get approved by a reviewing expert staff. It is even possible to mark (tag) revisions of selected articles for different purposes, let's say for an article validation aiming on a print edition. Furthermore, there is the possibility to let your readers give you evaluative feedbacks.
FlaggedRevs will make your wiki more reliable and thus more reputable over the time!
