Drupal 7.3, a maintenance release which fixes security vulnerabilities is now available for download.
Drupal 7.4 also fixes other issues reported through the bug tracking system.
Upgrading your existing Drupal 7 sites is strongly recommended. There are no new features in these releases. For more information about the Drupal 7.x release series, consult the Drupal 7.0 release announcement.
We have a security announcement mailing list, a history of all security advisories, and 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 status module, which informs you about important updates to your modules and themes.
Drupal 7.x is being maintained, so given enough bug fixes (not just bug reports), a new maintenance release will be made available the last Wednesday of next month (July 27).
Drupal 7.3 only includes fixes for security issues. Drupal 7.4 also includes bugfixes. The full list of changes between the 7.2 and 7.4 releases can be found by reading the 7.4 release notes. A complete list of all bug fixes in the stable 7.x branch can be found in the git commit log.
Drupal 7.3 was released in response to the discovery of security vulnerabilities. Details can be found in the official security advisory: SA-CORE-2011-002
To fix the security problem, please upgrade Drupal.
What is included with each release?
Shows a graph and that 7.3 should be used to upgrade quickly, 7.4 contains bug fixes and might need testing.
We make two versions of Drupal core available, so you can choose to only include security fixes (Drupal 7.3) or security fixes and bugfixes (Drupal 7.4). You can choose your preferred version. We are trying to make it easier and quicker to roll out security updates by making security-only releases available as well as ones with bugfixes included. We hope this helps you roll out the fixes as soon as possible. Read more details in the handbook.
