+* (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
+* (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
+ the "eIOPTZ" formatting characters.
+* EditWarning: A warning is shown when an editor leaves the edit form without
+ saving (enabled by default, users can opt-out via the 'useeditwarning'
+ preference). This feature was moved from the Vector extension, and is now part
+ of core for all skins. Take care when upgrading that you don't use an older
+ version of the Vector extension as this feature may conflict.
+* New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a
+ compact vertical form layout.
+* New versions of login (Special:UserLogin) and create account
+ (Special:UserLogin/signup) forms. They are opt-in for now, controlled by
+ the $wgUseVFormUserLogin and $wgUseVFormCreateAccount settings or a 'useNew'
+ URL parameter trigger.
+* (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
+ by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
+* The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
+ added.
+* (bug 25592) LogEventsList::showLogExtract() will now ignore various
+ Pager-related WebRequest parameters by default, as this is overwhelmingly
+ likely to be what was intended by users of the method. If any caller wishes
+ to use these parameters, the new param 'useRequestParams' may be set to true.
+* mw.util.addPortletLink: Tooltip is no longer required to be plain (without
+ an accesskey in it already). As such it now rountrips. Creating a link with a
+ message as tooltip, grabbing the title attribute and using it to create
+ another portlet will work as expected.
+* (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost
+ page without namespace.
