+* (T49162) Installer will default to setting CACHE_ACCEL as the main cache type
+ if it is available.
+* It is now possible to patrol file uploads (both for new files and new versions
+ of existing files). Special:NewFiles has gained an option to filter by patrol
+ status. This functionality can be disabled using $wgUseFilePatrol.
+* Added MWGrants and associated configuration settings $wgGrantPermissions and
+ $wgGrantPermissionGroups to hold configuration for authentication features
+ such as OAuth that want to allow restricting the user rights a user may make
+ use of.
+** If you're already using the OAuth extension, these new variables are
+ identical to (and will replace) $wgMWOAuthGrantPermissions and
+ $wgMWOAuthGrantPermissionGroups.
+* Added MWRestrictions as a class to check restrictions on a WebRequest, e.g.
+ to assert that the request comes from a particular IP range.
+* Whitelisted the following HTML attributes for all elements in wikitext:
+ aria-describedby, aria-flowto, aria-label, aria-labelledby, aria-owns.
+* Removed "presentation" restriction on the HTML role attribute in wikitext.
+ All values are now allowed for the role attribute.
