* 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 ====
* 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.
