Release notes

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

Drupal 9.1.x will receive security coverage until December 8, 2021 when Drupal 9.3.0 is released.

If you are upgrading from Drupal 8, read upgrading a Drupal 8 site to Drupal 9, 9.0.0 release notes, and the 9.1.0 release notes before upgrading to this release.

If your site is on 8.8.x or earlier, you may wish to upgrade to Drupal 8.9.13 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.

This release updates Symfony components to 4.4.35 (where applicable). Note that the Symfony CVE fixed by 4.4.35 does not affect Drupal core, so this is being released as a regular patch release.
