drupal 8.9.12

This is a patch (bugfix) release of Drupal 8 and is ready for use on production sites. Learn more about Drupal 8.

Drupal 8.9 is the final minor release of the 8.x series. It is a long-term support (LTS) version, and will receive security coverage until November 2021. It provides the same public API as Drupal 9.0 aside from deprecated code and dependency changes. (Learn more about Drupal 9.) Note that 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.

If you are upgrading to this release from 8.8.x, read the Drupal 8.9.0 release notes before you upgrade.
