== MediaWiki 1.43.0-PRERELEASE ==

== Upgrading notes for 1.43 ==
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 1.43 upgrades are below:

* 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.

  If this is deemed too long a maintenance operation (depending on the number
  of rows in the Linter database table), it is possible, for a upgrade from
  1.40 onwards, to run the migration scripts before updating the MediaWiki
  and extensions files to 1.43. Set $wgLinterWriteNamespaceColumnStage and
  $wgLinterWriteTagAndTemplateColumnsStage to true, and run the
  extensions/Linter/maintenance/migrateNamespace.php and
  extensions/Linter/maintenance/migrateTagTemplate.php migration scripts
  before proceeding with any other code update.
  When upgrading from a version <= 1.39, a multi-step update is necessary to
  be able to run the migration scripts independently from update.php: first
  update to 1.42, then proceed as indicated.
