+== MediaWiki 1.34.0-rc.1 ==
=== Changes since MediaWiki 1.34.0-rc.0 ===
* (T231742) rdbms: Restore debug toolbar "Queries" feature.
* (T235392) Deprecate setting Parser::mTitle to null.
* Supporting commits for T235392 were also backported to prevent divergence
from master (MediaWiki 1.35).
+* (T234581) The 'jquery.tabIndex' module is deprecated.
+* Fix docs for GetUserBlock hooks.
+* Parser: Hard deprecate getConverterLanguage.
+* (T236810) A number of public methods of Parser were exposed only for
+ historical reasons and have been deprecated: doMagicLinks,
+ doDoubleUnderscore, doHeadings, doAllQuotes, replaceExternalLinks,
+ replaceInternalLinks, replaceInternalLinks2, getVariableValue,
+ initialiseVariables, formatHeadings, testPst, testPreprocess, testSrvus,
+ areSubpagesAllowed, maybeDoSubpageLink, splitWhitespace, createAssocArgs,
+ armorLinks, makeKnownLinkHolder, getImageParams, parseLinkParameter,
+ stripAltText, replaceLinkHolders, replaceLinkHoldersText, armorLinks,
+ makeKnownLinkHolder, getImageParams, parseLinkParameter, stripAltText.
+* (T30798) $wgServer must now always be set in LocalSettings.php. This is most
+ likely the case already for any wiki installed after 1.18. The autodetection
+ system was informally deprecated since 1.18 and vulnerable to cache poisoning
+ attacks. Older wikis may need to update their LocalSettings.php file.
+* (T232169) Hard deprecate $wgSysopEmailBans.
+* (T236628) Fix for ArticleRevisionViewCustom hook in DifferenceEngine.php.
+* (T181658) Do not insert page titles into querycache.qc_value.
+* ParamValidator has been flagged as unstable.
+* Hard deprecate Parser::disableCache().

redirects in their userspace unless the target of the redirect is also in
their userspace. By default, this right is given to everyone.
* (T226733) Add rate limiter to Special:ConfirmEmail.
+* $wgDiffEngine (T237049) – This configuration can be used to specify which
+ difference engine to use. MediaWiki continues to default to automatically
+ choosing the first of $wgExternalDiffEngine, wikidiff2, or php that is
+ usable.
==== Changed configuration ====

'mime', 'mediadtype', 'bitdepth'.
Clients that process these fields should first check if 'filemissing' is
set. Fields that are supported even if the file is missing include:
- 'canonicaltitle', ''archivename' (deleted files only), 'descriptionurl',
+ 'canonicaltitle', 'archivename' (deleted files only), 'descriptionurl',
'descriptionshorturl'.
* The 'blockexpiry' result property in list=users and list=allusers will now be
returned in the same format used by the rest of the API: ISO 8601 for
testPst, testPreprocess, testSrvus, areSubpagesAllowed, maybeDoSubpageLink,
splitWhitespace, createAssocArgs, armorLinks, makeKnownLinkHolder,
getImageParams, parseLinkParameter, stripAltText, replaceLinkHolders,
