Which release do I choose? Security coverage information

• Drupal 9.1.x will receive security coverage until December 8, 2021 when 9.3.0 is released.
• Sites on 8.9.x should update immediately to Drupal 8.9.19 instead of this release, and update to Drupal 9 as soon as possible afterward because Drupal 8 is end-of-life in six weeks.
• Versions of Drupal 9 prior to 9.1.x and of Drupal 8 prior to 8.9.x are end-of-life and do not receive security coverage.

Important update information

• No changes have been made to the .htaccess, web.config, robots.txt, or default settings.php files in this release, so upgrading custom versions of those files is not necessary if your site is already on the previous release.
