+* The following methods of OutputPage are now deprecated in favour
+ of using showFatalError directly: OutputPage::showFileDeleteError()
+ OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
+ OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
+* The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
+ classes are now deprecated. Use a Closure instead.
+* (T194263) ContentHandler::makeParserOptions() is deprecated. Use
+ WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
+* (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
+ MediaWiki 1.26, is now hard-deprecated. All known clients were converted to
+ the Parsoid v3 API in May 2015.
+* $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
+ $formDescriptor instead.
+* SearchEngine::transformSearchTerm( $term ) should no longer be called prior
+ to running searchText. This method was mainly implemented to support the
+ 'prefix' URI param in SpecialSearch, but there are no reasons to expose this
+ logic as it should be handled internally by SearchEngine implementations
+ supporting this feature. SearchEngine implementations should no longer
+ override this methods.
+* SearchEngine::replacePrefixes( $query ) should no longer be called prior
+ to running searchText/searchTitle.
+* (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
+ 'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
+* Global functions wfArrayFilter() and wfArrayFilterByKey() are deprecated.
+ use array_filter() directly.
