Perer Gammie and I are working on reversion over at [[todo/web_reversion]].

+
+Update: Web reversion is now supported by ikiwiki. Only changes committed
+to your wiki after you upgrade to the version of ikiwiki that supports it
+will get revert buttons on the RecentChanges page. If you want to force
+adding buttons for older changes, you can delete `recentchanges/*._change`
+from your srcdir, and rebuild the wiki. --[[Joey]]
