* Completely new user interface for the RecentChanges page, which
structures filters into user-friendly groups. This has corresponding
changes to how filters are registered by core and extensions.
+* The edit form now uses pretty OOjs UI buttons, checkboxes and summary input.
+ Because this change can cause problems for extensions and on-wiki
+ scripts depending on the exact HTML, the old version is still available
+ and can be used by setting $wgOOUIEditPage = false; in LocalSettings.php.
+ This will be removed later and OOjs UI will become the only option.
+ To make testing easier, users can also force either mode by adding
+ &ooui=true or &ooui=false to the action=edit URL.
