Update: Drupal 7.22 is now available.

Drupal 7.21, a maintenance release which fixes incompatibilities introduced in the Drupal 7.20 security release, is now available for download. See the Drupal 7.21 release notes for further information.

Download Drupal 7.21

Upgrading your existing Drupal 7 sites is strongly recommended, especially if you encountered problems with Drupal 7.20. There are no new features in this release. For more information about the Drupal 7.x release series, consult the Drupal 7.0 release announcement.

Security information

We have a security announcement mailing list and a history of all security advisories, as well as an RSS feed with the most recent security advisories. We strongly advise Drupal administrators to sign up for the list.

Drupal 7 includes the built-in Update Manager module, which informs you about important updates to your modules and themes.

There are no security fixes in this release of Drupal core; however, sites which were unable to upgrade to Drupal 7.20 (or upgraded but made modifications to disable the security fixes included within it) should upgrade to Drupal 7.21 to obtain additional security protection. See the Drupal 7.21 release notes for further information.

Bug reports

Drupal 7.x is being maintained, so given enough bug fixes (not just bug reports), more maintenance releases will be made available, according to our monthly release cycle.

Changelog

Drupal 7.21 is a bug fix only release. The full list of changes between the 7.20 and 7.21 releases can be found by reading the 7.21 release notes. A complete list of all bug fixes in the stable 7.x branch can be found in the git commit log.
