* Introduced $wgVerifyMimeTypeIE to allow disabling the MSIE 6/7 file type
detection heuristic on upload, which is more conservative than the checks
that were changed above.
+* $wgExternalDiffEngine — Setting this to a string value of 'wikidiff',
+ 'wikidiff2', or 'wikidiff3' will no longer work. This legacy behaviour was
+ deprecated in MediaWiki 1.27, 1.32, and 1.27, respectively.
* $wgSkipSkin — Setting this instead of $wgSkipSkins, deprecated in 1.23, is now
hard-deprecated.
* $wgLocalInterwiki — Setting this instead of $wgLocalInterwikis, deprecated in
* User::setNewpassword(), deprecated in 1.27 has been removed.
* The ObjectCache::getMainWANInstance and ObjectCache::getMainStashInstance
functions, deprecated since 1.28, have been removed.
+* Language::$dataCache has been removed (without prior deprecation, for
+ practical reasons). Use MediaWikiServices instead to get a LocalisationCache.
=== Deprecations in 1.34 ===
* The MWNamespace class is deprecated. Use NamespaceInfo.
* ApiQueryBase::showHiddenUsersAddBlockInfo() is deprecated. Use
ApiQueryBlockInfoTrait instead.
* PasswordReset is now a service, its direct instantiation is deprecated.
+* RESTBagOStuff users should specify either "JSON" or "PHP" serialization type.
+* The global function wfIsHHVM() is deprecated and will now always return false
+ regardless of the runtime environment. This is part of the continuing work to
+ remove HHVM support from MediaWiki, which started in MediaWiki 1.31.
+* Language::getLocalisationCache() is deprecated. Use MediaWikiServices
+ instead.
+* The following Language methods are deprecated: isSupportedLanguage,
+ isValidCode, isValidBuiltInCode, isKnownLanguageTag, fetchLanguageNames,
+ fetchLanguageName, getFileName, getMessagesFileName, getJsonMessagesFileName.
+ Use the new LanguageNameUtils class instead. (Note that fetchLanguageName(s)
+ are called getLanguageName(s) in the new class.)
