You can browse each version of the MW code HERE.

1.39

I have checked the release notes through 1.39.9.
  • Only small issues have been fixed since our current version of 1.39.6.

1.40

I have checked the release notes through 1.40.3.
  • Requires PHP 7.4.3+ and the PHP extensions ctype, dom, fileinfo, iconv, intl, json, mbstring, xml.
  • 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)
  • The preferences page now provides a search bar to find preferences, regardless of the tab on which they appear.
  • $wgPasswordPolicies – This setting, which controls what makes for a valid password for wiki accounts, has been adjusted to raise the minimal password length from 1 to 8 characters. The initial limit of 1 has been in place since MediaWiki 1.26. If you wish to allow shorter passwords, you can over-ride it in your LocalSettings following the guidance on MediaWiki.org.
  • You should configure your webserver to return the http header 'X-Content-Type-Options: nosniff' for the /images directory. This will instruct browsers to not apply content sniffing when accessing the files. MediaWiki before 1.40 shipped with a content sniffer which disallowed potentially dangerous files at upload time, but this protection has now been removed in favor of this 'X-Content-Type-Options: nosniff' header and the installer will return a warning when it is not in place.
  • Maintenance scripts should now be executed using maintenance/run.php, e.g. maintenance/run.php update not maintenance/update.php as before.
  • Five extensions have now been bundled with MediaWiki:
    • The DiscussionTools extension, which provides a forum-like editing experience for wikitext-based discussion pages. This is the dreaded new "forum-like" experience for talk pages that I don't think any of us will want. It seems like it will be on by default so we'll have to change $wgDiscussionToolsEnable to false. Hopefully it doesn't do anything to mess with talk pages immediately upon install.
    • The Echo extension, which provides a system of user notifications.
    • The Linter extension, which warns about use of deprecated wikitext.
    • The LoginNotify extension, which warns users about failed attempted logins.
    • The Thanks extension, which lets users thank editors for edits.
  • The Renameuser extension has been moved to MediaWiki core. It is now possible to rename users without installing an extension. The extension had already been bundled with MediaWiki since 1.18.

1.41

I have checked the release notes through 1.41.4.
  • Requires PHP 7.4.3+ and the PHP extensions ctype, dom, fileinfo, iconv, intl, json, mbstring, xml.
  • MediaWiki now requires browsers to support ES6 for them to receive JavaScript, up from ES5. In practice, this primarily means that users of Internet Explorer 11 (EOL in 2022) will no longer get JavaScript tools.
  • Some interesting new configuration variables:
    • $wgImplicitRights - A list of implicit rights, in addition to the ones defined by the core. Rights in this list are granted implicitly to all users, but rate limits may apply to them.
    • $wgInterwikiLogoOverride - List of interwiki logos overrides.
    • $wgSVGNativeRendering - Whether native SVG rendering by the browser agent is allowed
    • $wgSVGNativeRenderingSizeLimit - If $wgSVGNativeRendering is set to 'partial', this sets the size limit for an SVG file to be rendered as a PNG instead of directly by the browser.
    • $wgWikidiff2Options - Configuration for Wikidiff2. Is Wikidiff2 used by default in 1.41? If so, it seems that they may have added new options and that's the reason they added this array variable. See here for docs.
    • $wgEnableEditRecovery - Enables a beta edit-saving feature that prevents data loss if the window closes. Apparently Visual Editor already has its own edit-saving feature that is almost as good.

1.42

I have checked the release notes through 1.42.4.
  • MediaWiki now requires Composer 2.x, and any related (vendor) files generated by Composer must be generated by Composer 2.x. Composer 1.x is mostly end-of-life upstream, and using it will result in slower actions when downloading and installing packages.
  • filter: is now allowed in inline CSS in wikitext.

1.43

I have checked the release notes through 1.43.0.
  • It is now necessary that the OpenSSL PHP extension is installed.
  • update.php updates the Linter database table with two migration scripts that can take a long time to run: with the provided settings, each migration script update roughly 500 rows per second. If at all possible, it is highly recommended to let update.php run these migration scripts.
  • Special:TalkPage is a new special page that will redirect to the associated talk namespace page, e.g. Special:TalkPage/Foo redirects to Talk:Foo; Special:TalkPage/Project:Foo goes to Project talk:Foo. This allows for links by templates and tools without having to parse what namespaces are valid and have associated talk pages.
  • Special:NamespaceInfo is a new special page that displays a list of namespaces available on the wiki, their descriptions and configuration.
