Update: Drupal 7.28 and Drupal 6.32 are now available.
Drupal 7.27 and Drupal 6.31, maintenance releases which contain fixes for security vulnerabilities, are now available for download. See the Drupal 7.27 and Drupal 6.31 release notes for further information.
Upgrading your existing Drupal 7 and 6 sites is strongly recommended. There are no new features or non-security-related bug fixes in these releases. For more information about the Drupal 7.x release series, consult the Drupal 7.0 release announcement. More information on the Drupal 6.x release series can be found in the Drupal 6.0 release announcement.
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 and 6 include the built-in Update Status module (renamed to Update Manager in Drupal 7), which informs you about important updates to your modules and themes.
Drupal 7.27 and 6.31 were released in response to the discovery of security vulnerabilities. Details can be found in the official security advisory:
To fix the security problem, please upgrade to either Drupal 7.27 or Drupal 6.31.
- This security release introduces small API changes which may require code updates on sites that expose Ajax or multi-step forms to anonymous users, and where the forms are displayed on pages that are cached (either by Drupal or by an external system). See the Drupal 7.27 release notes and Drupal 6.31 release notes for more information.
- (Drupal 7 only) This release caused the Multiple Forms module to stop working correctly (see issue). The solution is to upgrade to Multiple Forms 7.x-1.1 or higher.
