Maintenance and security release of the Drupal 9 series.
This release fixes security vulnerabilities. Sites are urged to upgrade immediately after reading the notes below and the security announcement:
No other fixes are included.
Which release do I choose? Security coverage information
- Sites on 9.1.x or earlier should update immediately to Drupal 9.1.11 instead, and plan to update to the latest 9.x release before December 8, 2021 (when Drupal 9.3.0 is scheduled for release and 9.1.x security coverage ends).
- Sites on 8.9.x should update immediately to Drupal 8.9.17 instead, and update to Drupal 9 as soon as possible because Drupal 8 is end-of-life in three months.
- 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 defaultsettings.phpfiles in this release, so upgrading custom versions of those files is not necessary if your site is already on the previous release.
