Update: Drupal 7.19 and Drupal 6.28 are now available.
Drupal 7.18 and Drupal 6.27, maintenance releases which contain fixes for security vulnerabilities, are now available for download. See the Drupal 7.18 and Drupal 6.27 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.
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 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.
Bug reports
Both Drupal 7.x and 6.x are being maintained, so given enough bug fixes (not just bug reports) more maintenance releases will be made available, according to our monthly release cycle.
