=== New features in 1.26 ===
* (T51506) Now action=info gives estimates of actual watchers for a page.
* Caches that need purging ability now use the WANObjectCache interface.
This corresponds to a new $wgMainWANCache setting, which defaults to using
the $wgMainCacheType settings.
+* Added MWTimestamp::getTimezoneString() which returns the localized timezone
+ string, if available. To localize this string, see the comments of
+ $wgLocaltimezone in includes/DefaultSettings.php.
* Callers needing fast light-weight data stores use $wgMainStash to select
the store type from $wgObjectCaches. The default is the local database.
* Interface message overrides in the MediaWiki namespace will now be cached in
page. During the deprecation period, the styles will only be loaded on pages
which contain 'mw-ui-button' in their HTML. Starting in 1.28, the styles will
only be loaded if explicitly required.
+* If search returns zero results and current search engine has a "did you mean"
+ suggestion, results for suggestion will be shown. Can be disabled by setting
+ $wgSearchRunSuggestedQuery to false.
