* Introduced $wgPagePropsHaveSortkey as a backwards-compatibility switch,
for using the old schema of the page_props table, in case the respective
schema update was not applied.
+* $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything'
+ user option was removed. Use $wgNamespacesToBeSearchedDefault instead or
+ if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
=== New features in 1.24 ===
* Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This is only for page views,
since this hook doesn't affect UserLogin, OAuth, CentralAuth, etc.
ATTENTION: This hook is likely to be removed soon due to overall design of the system.
+* (bug 17367) It is now possible to add pages to your watchlist from
+ Special:UnwatchedPages without reloading the special page.
+* New methods setVolatile and isVolatile are added to PPFrame, so that
+ extensions such as Cite.php can mark that their output is volatile and
+ shouldn't be cached.
+* (bug 52817) Advanced search options are now saved on the search page itself, rather
+ than in a dedicated pane in the preferences panel.
=== Bug fixes in 1.24 ===
* (bug 49116) Footer copyright notice is now always displayed in user language
core to their own respective repositories. See also
https://www.mediawiki.org/wiki/Skin:Modern and
https://www.mediawiki.org/wiki/Skin:CologneBlue.
+* BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
+ the "headelement" template key are no longer supported. Setting
+ $useHeadElement = false; is no longer supported and will not cause old keys
+ like "headlinks", "skinnameclass", etc. to be defined.
