  === New features in 1.20 ===
  * Added TitleIsAlwaysKnown hook which gets called when determining if a page exists.
+ * Added NamespaceIsMovable hook which gets called when determining if pages in a
+   certain namespace can be moved.
  * (bug 32341) Add upload by URL domain limitation.
  * &useskin=default will now always display the default skin. Useful for users with a
    preference for the non-default skin to look at something using the default skin.
@@@ -56,10 -58,6 +58,10 @@@
  * (bug 5445) Now remove autoblocks when a user is unblocked.
  * Added $wgLogExceptionBacktrace, on by default, to allow logging of exception
    backtraces.
 +* Added device detection for determining device capabilities.
 +* QUnit.newMwEnvironment now supports passing a custom setup and/or teardown function.
 +  Arguments signature has changed. First arguments is now an options object of which
 +  'config' can be a property. Previously 'config' itself was the first and only argument.
  
  === Bug fixes in 1.20 ===
  * (bug 30245) Use the correct way to construct a log page title.
