drupal 9.0.10

This is a patch (bugfix) release of Drupal 9 and is ready for use on production sites. Learn more about Drupal 9.

Drupal 9.0.x will receive security coverage until June 16, 2021 when Drupal 9.2.0 is released. It will no longer receive bugfix releases now that Drupal 9.1.0 has been released

If you are upgrading from Drupal 8, read upgrading a Drupal 8 site to Drupal 9 and the 9.0.0 release notes before upgrading to this release.

If your site is on 8.8.x or earlier, you may wish to upgrade to Drupal 8.9.11 instead. Regardless of which version you choose now, features will only be added to Drupal 9 minor releases, so plan to adopt Drupal 9 as soon as possible so that you can easily update to Drupal 9.2 and later.
