Still on Drupal 7? Security support for Drupal 7 ended on 5 January 2025. Please visit our Drupal 7 End of Life resources page to review all of your options.
Maintenance release of the Drupal 7 series. Includes bugfixes and small API/feature improvements only (no major new functionality); significant new features are only being added to the forthcoming Drupal 8.0 release.
No security fixes are included in this release.
Besides documentation fixes, no changes have been made to the .htaccess, robots.txt or settings.php files in this release, so upgrading custom versions of those files is not necessary.
Under rare circumstances, upgrading to Drupal 7.15 may cause sites to experience a fatal error. This occurs for sites which have sub-themes in their filesystem and modules installed that perform unusual actions early in Drupal's bootstrap process (example: the Environment module). The Registry Rebuild script is also affected, although the latest development version is not. The root cause of the bug has been fixed in the 7.x-dev version of Drupal core, and a patch for Drupal 7.15 is available in the above-mentioned issue.
