If using PHP 8, it is recommended to use MediaWiki 1.38.4 or higher. PHP 8 is not in use by Wikimedia wikis, and thus gets less testing, but other groups do use MediaWiki with PHP 8 without issue. If you encounter any bugs when using MediaWiki with PHP 8, please report them. See task T248925 for more information.
Warning:
MediaWiki 1.36.0 to 1.36.2 contain a very severe security issue. Please upgrade to 1.36.3 or later. See 2021-12 security release/FAQ for more information.
MediaWiki 1.36 is an obsolete release of MediaWiki.
Consult the RELEASE NOTES file for the full list of changes.
It was deployed on Wikimedia Foundation wikis through incremental "wmf"-branches between 21 July 2020 and 15 April 2021.
The 1.36.0 stable release came out on May 27, 2021.
Download 1.36.4 or checkout the REL1_36 branch in Git to follow this release.
The 1.36 branch, with the version 1.36.4, reached its end-of-life on 03 June 2022.
`Access-Control-Max-Age` was added to the default list of headers allowed for cross-origin API requests ($wgAllowedCorsHeaders).
Accounts with the 'bot' right no longer have pages automatically added to the watchlist when making API edits, regardless of their preferences. This is to reduce the size of the watchlist data in the database. To add API bot edits to the watchlist, explicitly set the 'watch' option.
(T275334) $wgExtensionFunctions is sometimes used to change configuration settings. This is not safe; extension functions are run relatively late, some services are already initialised by that point and so they use the old configuration. Changes in 1.36 make this kind of breakage even more common. You can use the MediaWikiServices hook instead. (In the future there might be a dedicated hook for configuration changes.)
The MediaWiki update script, maintenance/update.php, used to accept `--nopurge` as an option to prevent clearing caches stored in the database during upgrade. This is no longer encouraged, and the option has been removed.
(T256001) $wgManualRevertSearchRadius – This setting controls a new feature that marks edits as reverts if they restore the page to an exact previous state. This configuration variable sets the maximum number of revisions of a page that will be checked against every new edit. Set this to 0 to disable the feature entirely.
(T265263) $wgRememberMe - This setting configures the "remember me" checkbox on account log-in systems via RememberMeAuthenticationRequest.
(T157145) $wgSkinMetaTags – This setting lets sysadmins configure skins that support meta tags. These tags make sharing of MediaWiki pages on a variety of social platforms more contentful and thus useful.
(T280944) $wgIncludejQueryMigrate – This setting lets sysadmins disable the jQuery Migrate plugin. It has been enabled by default since MediaWiki 1.27. In future releases it will be disabled by default.
$wgLogos – This setting selects the logo shown on the site. The default value for the site logo, which is shown in an install if you have not set one, will now be the new logo of MediaWiki.
(T274695) $wgAjaxEditStash — This setting, to disable the edit stashing feature when users start writing an edit summary, has been deprecated. In future releases, this feature will always be enabled.
$wgWANObjectCaches – The "coalesceKeys" option was removed without deprecation and replaced by a new "coalesceScheme" option, set to "hash_stop" by default. If you use Dynomite, then set the new "coalesceKeys" option to "hash_tag". The "cluster" and "mcrouterAware" options were also removed without deprecation. Use "broadcastRoutingPrefix" instead.
$wgAllowImageMoving — This setting, deprecated in 1.35, has been removed. Use group permission settings instead. For example, to prevent sysops from moving files, set $wgGroupPermissions['sysop']['movefile'] = false;`
$wgParserConf — This setting, deprecated in 1.35, has been removed. The last use of this setting was for pre-processor configuration, which was deprecated in 1.34 and removed in 1.35.
$wgEnableRestAPI — This setting, ignored since 1.35, has been removed.
$wgPagePropsHaveSortkey – This temporary setting has been removed, along with the schema change upgrade path it controlled. If your site is still using it, meaning you have not yet applied the `pp_sortkey` schema change from 1.24, you must now apply it before upgrading.
The deprecated password policies PasswordCannotMatchBlacklist and PasswordNotInLargeBlacklist were removed. Please use PasswordCannotMatchDefaults and PasswordNotInCommonList respectively instead.
