+* For namespaces with $wgNamespaceProtection (including the MediaWiki
+ namespace), the "protect" tab will be shown only if there are restriction
+ levels available that would restrict editing beyond what
+ $wgNamespaceProtection already applies. The protection form will offer only
+ those protection levels.
+* Added $wgAPIFormatModules, allowing extensions to add additional output
+ formatting modules for the API.
