  * 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.
