* $wgRevisionCacheExpiry is now set to one week by default instead of being disabled.
+* Magic links are now disabled by default, and can be re-enabled by modifying the value
+ of $wgEnableMagicLinks. Their usage is discouraged, but if they are manually enabled,
+ a tracking category will be added to help identify usage and make it easier to migrate
+ away from. If you depend upon magic link functionality, it is requested that you comment
+ on <https://www.mediawiki.org/wiki/Requests_for_comment/Future_of_magic_links> and
+ explain your use case(s).
