More bundled extensions


The set of extensions that are bundled with the MediaWiki tarball has increased. The new additions are:
 * provides a more friendly editor when editing CSS and JavaScript on-wiki.
 * provides a lightbox viewer for images and galleries.
 * provides two-factor authentication for wiki accounts.
 * provides a form to let administrators do string replacements on the entire wiki, for both page contents and page titles.

Tidy replaced with HTML 5 parsing algorithm

 * See the frequently asked questions for more details

The HTML 4 based Tidy library has been replaced by a pure-PHP HTML 5 parser to clean up improper wikitext in a modern and standards compliant way. If your content relied on some of the tidy fix-ups that are not being continued, they will need to be fixed. [Something about how in the long-run this will all be better. Pointers to Linter and ParserMigration].

Interwiki usernames

 * Imports will now record unknown (and, optionally, known) usernames in a format like " ".
 * (used on history pages, log pages, and so on) will display usernames formed like " Example" as interwiki links, as if by wikitext like.

Further UI standardization

Other feature changes

 * Add default edit rate limit of 90 edits/minute for all users.
 * Make only affect edit actions.
 * User sub-pages named  are now protected in the same way that   and   pages are, so that configuration options can safely be placed there.
 * The info page for File pages now displays the file's base-16 SHA1 hash value in the table of basic information.


 * Added a monthly heartbeat ping to the pingback feature.
 * Tabs which link to pages that don't exist (like those to uncreated discussion pages) now have a tooltip to indicate state, not just colour.

Languages updated in 1.31
MediaWiki supports over 350 languages. Many localisations are updated regularly. Below only new and removed languages are listed, as well as changes to languages because of Phabricator reports.


 * Mirandese (mwl) now supports gendered /.
 * New language support: Nyungar (nys).
 * New language support: Siberian Tatar [cебертатар] (sty).
 * New language support: Guianan Creole (gcr).
 * New language support: Kumyk [къумукъ] (kum).
 * New language support: Spanish formal address (es-formal).
 * New language support: Hungarian formal address (hu-formal).
 * New language support: Gorontalo (gor).

PHP7 or HHVM is now required
MediaWiki 1.31 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is supported, it is generally advised to use PHP 7.0.0 or later for long term support.

Database changes
1.31 has several database changes since 1.30, and will not work without schema updates.

Revision table
Note that due to changes to some very large tables like the revision table, the schema update may take quite long (minutes on a medium sized site, many hours on a large site). Don't forget to always back up your database before upgrading!

Archive table
If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply schema changes, and cannot have downtime to run  and apply   manually, you'll have to apply a default value to the   and   columns of the   table or make those columns nullable before upgrading to MediaWiki 1.31. shows how to do this for MySQL.

Actor table
The identity of the logged-in or IP "actor" for logged actions is being moved into a new  table, with the rows in tables such as revision and logging referring to the actor ID instead of storing the user ID and name/IP in every row.


 * This is currently gated by . Most wikis can set this to  and run   as soon as any necessary extensions are updated.
 * Most code accessing rows for logged actions from the database should use the relevant  methods to get the information needed to build the SQL query. The   class may also be used to get feature-flagged information needed to access actor-related fields during the migration period.

Configuration changes

 * and are now deprecated and will be removed in a future version. The API is now considered to be stable, secure and essential.
 * was removed, as it is now the default. This was documented as a temporary variable during the migration period, deprecated since 1.29.

 * The old  feature, including its related configuration option, has been removed.
 * The ' ' value for is no longer supported for performance reasons, and installations with this setting will now work as if it was configured with ' '.

 * now defaults to  instead of.
 * was removed and will be ignored.
 * , deprecated and ignored since 1.25, was removed. See the 1.25 release notes for more information.
 * is now marked as deprecated, just like the deprecated AJAX framework that it enables. Some extensions mistakenly used this to check whether any AJAX functionality at all should be enabled, further making this problematic to retain.
 * is now deprecated, and will be removed in a future version. It has been marked as experimental ever since it was introduced.
