* Revive the 'SpecialSearchResultsAppend' hook which occurs after the list of
search results are rendered. The initial use case is to append a "give us
feedback" link beneath the search results.
+* Added a new hook, 'RejectParserCacheValue', which allows extensions to
+ reject an otherwise-successful parser cache lookup. The intent is to allow
+ extensions to manage the eviction of archaic HTML output from the cache.
==== External libraries ====
* wfSuppressWarnings() and wfRestoreWarnings() were split into a separate library,
mediawiki/at-ease, and are now deprecated. Callers should use
MediaWiki\suppressWarnings() and MediaWiki\restoreWarnings() directly.
+* The Block class constructor now takes an associative array of parameters
+ instead of many optional positional arguments. Calling the constructor the old
+ way will issue a deprecation warning.
+* The jquery.mwExtension module was deprecated.
