Drupal 4.7.6 and 5.1 are available for download. These are maintenance releases that fix problems reported using the bug tracking system, as well as a security vulnerability.

Upgrading your existing Drupal sites is strongly recommended.


There are no new features in these installments. For more information about the Drupal 4.7.x release series, please consult the Drupal 4.7.0 release announcement. For more information about the Drupal 5.x release series, consult the Drupal 5.0 release announcement.

A complete list of all bug fixes in the stable DRUPAL-4-7 branch can be found at http://drupal.org/project/cvs/3060/?branch=DRUPAL-4-7.

Security vulnerabilities

Drupal 4.7.6 and Drupal 5.1 fix one security vulnerability. Details can be found in the official security advisory:

  1. http://drupal.org/files/sa-2007-005/advisory.txt

To fix this security problem, you can (1) upgrade Drupal or (2) patch Drupal.

  1. To upgrade Drupal, consult the information below.
  2. To fix the security issue in Drupal 4.7.5, use the patch below:
  3. To fix the security issue in Drupal 5.0, use the patch below:

We recommend you do the full upgrade as the patches do not contain the many additional bugfixes that went into the releases. Applying the patches will leave your site in a somewhat unversioned state, but at least secure.


To upgrade Drupal, follow the upgrade instructions.

For the most trouble-free transition from an existing installation, it is recommended that you first upgrade to Drupal 4.7.5 or Drupal 5.0. If you are upgrading from Drupal 4.5.x or below, please consult the Drupal 4.6.0 release announcement. As with any upgrade, it is a good idea to back up your site and database first.

Security infrastructure

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.

Bug reports

Both Drupal 4.7 and 5 branches are being maintained, so given enough bug fixes (not just bug reports) more maintenance releases will be made available.
