+* The ability to override User::$mRights has been removed.
+* Previously, when iterating ResultWrapper with foreach() or a similar
+ construct, the range of the index was 1..numRows. This has been fixed to be
+ 0..(numRows-1).
+* The ChangePasswordForm hook, deprecated in 1.27, has been removed. Use the
+ AuthChangeFormFields hook or security levels instead.
+* WikiMap::getWikiIdFromDomain(), deprecated in 1.33, has been removed.
+ Use WikiMap::getWikiIdFromDbDomain() instead.
+* The config variables $wgHtml5, $wgJsMimeType, and $wgXhtmlDefaultNamespace,
+ which were deprecated and ignored by core since 1.22, are no longer set to any
+ value, and SkinTemplate no longer emits a 'jsmimetype' key. Any extensions not
+ updated since 2013 to cope with this deprecation may now break.
