Mediawiki 1.43

MediaWiki 1.43 is the new Long-Term Support (LTS) version of MediaWiki. The 1.43.0 stable release was tagged on 21 December 2024.

Karsten Hoffmeyer of ProWiki wrote a good summary about key features and changes. For full details see the Release notes on-wiki or the raw text version in the RELEASE-NOTES-1.43 file in the source code.

Upgrade requirement notes[edit | edit source]

The OpenSSL PHP extension is required.
If you use the Linter extension (which helps you to avoid syntax problems in your wikitext) pay special attention: while update.php will handle updates to the Linter database table with two migration scripts, they can take a long time to run. To avoid downtime, you can run the scripts independent of the code upgrade - but if you want to do that then you must already be running (upgrade first to) v1.42.

To get to 1.43, we'll be upgrading from the prior LTS version: 1.39. So, it is imperative to understand the changes taking place in 1.40, 1.41 and 1.42.

Upgrade notes for 1.40[edit | edit source]

See ProWiki's write-up at https://www.pro.wiki/articles/mediawiki-140-is-new and the on-wiki Release notes for 1.40 for full details.

The Renameuser extension is now merged into core - so it must be removed if you use it in REL1_39

There are newly bundled extensions: Echo, DiscussionTools, Linter, LoginNotify, and Thanks.

Maintenance scripts are now called through maintenance/run.php e.g. maintenance/run.php update not maintenance/update.php

Configure your webserver to emit the HTTP header X-Content-Type-Options: nosniff for your wiki's /images directory.

New user-facing features in 1.40[edit | edit source]

Special:Search can now show thumbnails for results for titles outside NS_FILE. This is controlled via the new onSearchResultProvideThumbnail hook.
A new preference ('search-thumbnail-extra-namespaces') to allow users to control whether to show more thumbnails (per $wgThumbnailNamespaces)
(T324910) On pages using multi-content revisions, the raw content of a specific slot can be retrieved using the action=raw&slot=<role-name> query parameters.
(T313804) The preferences page now provides a search bar to find preferences, regardless of the tab on which they appear.
