Drupal 7.21 released
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.
