This week and next week we're deploying a new version of MediaWiki to your wiki, as usual. This upgrade includes one-click (AJAX) patrolling, for both new page and diff patrol (see bug 7851). [...]
Thank you, useful summary. I think the new AJAX patrolling makes this a real milestone. ;-) I already notified a few days ago the users and wikis which used the gadget https://meta.wikimedia.org/wiki/User:Krinkle/Scripts/AjaxPatrolLinks.
