== Upgrading notes for 1.40 ==
Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed per-version upgrade instructions from the
oldest supported upgrading version, MediaWiki 1.35.

Some specific notes for MediaWiki 1.40 upgrades are below:
* Maintenance scripts should now be executed using maintenance/run.php, e.g.
  maintenance/run.php update not maintenance/update.php as before.
* Four extensions have now been bundled with MediaWiki:
  * 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.
