Drupal 9.4.9 was released on December 7, 2022 and is the final full bugfix release for the Drupal 9.4.x series. Drupal 9.4.x will not receive any further development aside from security fixes. Drupal 9 bug reports should be targeted for the 9.5.x-dev branch from now on, and new development or disruptive changes should be targeted for the 10.1.x-dev branch. For more information see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch. For more information, see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.
