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]

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.

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.

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)
(Template:PhabT) 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.
(Template:PhabT) The preferences page now provides a search bar to find preferences, regardless of the tab on which they appear.
