Hello world,
Drupal 4.6.4 is available for download. Drupal 4.6.4 is a maintenance release that fixes problems reported using the bug tracking system, as well as 3 security vulnerabilities (two "less critical", one "not critical") that affect all previous versions of Drupal. Since the vulnerabilities are also present in the Drupal 4.5 series, Drupal 4.5.6 is released as well. Upgrading your existing Drupal sites is strongly recommended.
More information about the Drupal 4.6.4 and 4.5.6 release is available at http://drupal.org/drupal-4.6.4.
Security advisories are available at http://drupal.org/security.
Kudos to the security team for their work on getting these releases out,
