MediaWiki 1.25 is currently being developed.

Consult the  file for the full list of changes.

It is currently deployed on Wikimedia Foundation wikis through incremental "wmf"-branches starting September 25, 2014.

The 1.25.0 stable release is expected to come out on Monday, May 25, 2015.

New features

 * Help:Page status indicators. You may want to adapt some templates and scripts on your wiki if you're e.g. adding icons on top right corner of the page.

Enhanced recent changes


MediaWiki now uses by default the extended watchlist and so called enhanced recent changes (preference ""), which also received several improvements in MediaWiki 1.24 and 1.25.

This means that Special:RecentChanges and Special:Watchlist show all the changes to each page in a given day, sorted by page rather than chronologically. Changes to each page are collapsed by default and a compact overview is shown, with links to collated diffs and counts of each user's actions. Full activity for an individual page can then be shown with a single click.

Users will no longer need to know in detail how a single change was chosen for display in order to figure out what else may have happened to the page that day, nor to scan a long list of non-contiguous lines on the screen in order to get a complete picture. The change is part of MediaWiki's evolution towards an interface which is more discoverable and less cluttered by default, while equally easy to quickly access in full, with the help of JavaScript. However, the (grouped) layout is an improvement for non-JavaScript users as well.

Live preview
While editing, you're not sure what a wikitext syntax will produce? That's no longer a problem, now that live preview is no longer experimental. By enabling the feature in your preferences, MediaWiki will display the effect of your edits without fully reloading the page, so that you can quickly correct any mistake.

Performance
Frontend performance work continues.
 * Some 4 KB of HTML less on each MediaWiki page.

Import
Thanks to This, that and the other, import is now much easier from a wiki which has different namespaces than yours (e.g. because it's in another language).

Logging and gender
Continuing the work in MediaWiki 1.18 and 1.19, Umherirrender has migrated multiple log types of Special:Log to the new logging system, which allows full internationalization including word order and grammatical gender. The migration is now complete. See T26620 for a list.

New locales
The following locales have been added:

Breaking changes

 * PHP 5.3.3 or newer is now required to run MediaWiki.
 * The legacy skinning system, that uses skin autodiscovery, will be removed (deprecated since 1.23) and will be completely replaced with a new skinning system used like extensions on MediaWiki. This skinning system has been introduced with some minor changes since MediaWiki 1.12.
 * jQuery Migrate removed. Please see TODO on how to fix your local JavaScript.
 * The OpenSearchXml extension was merged into MediaWiki core. If you have it installed, you should undeploy it.

Configuration changes
More configuration defaults have been flipped, to reduce the strain needed by most administrators to get a sensibly-configured install. See the full release notes for details.

Less invasive profiling
The entire profiling system has been overhauled to be more flexible and less invasive using the xhprof extension. Manual  and   function calls are no longer needed and should be removed. See Manual:Profiling for an overview of the new options and how to update your.

External libraries
As part of the Library infrastructure for MediaWiki project, MediaWiki core now uses composer for managing external dependencies instead of copying the files into our code repo, such as CSSJanus and lessphp. In addition, non-MediaWiki specific code that was originally written for MediaWiki such as the cdb libraries have been split out into their own repos.

The tarball will contain these dependencies and the upgrade process for tarball users should stay the same. Users who have cloned from git will need to follow the instructions at Download from Git. Installed libraries will be displayed upon Special:Version in their own section.

Better support for composer-managed extensions
composer.json was previously used for composer-managed extensions, but it is now used for managing dependencies of MediaWiki core. After discussions regarding this issue, a composer-merge-plugin was developed so sysadmins could specify their dependencies in a. More documentation is available at Composer/For extensions.

Structured logging
TODO: Fill this in
