July 1st, 2009 was a big day for content management systems updates! First Joomla! updated to 1.5.12, and then Drupal released a security maintenance upgrade.
Drupal was updated because of fixes being made available for multiple security bugs which threaten to compromise the website via Cross Site Scripting (XSS) and URL-crafting techniques.
The 5.x branch of Drupal is only receiving security updates. However, 6.x branch users who perform the upgrade will receive 20+ other bug fixes to their installation. For a complete set of release notes for each version, as well as technical information related to the security issues fixed, see the release announcement here.
Drupal.org and F.H. Black & Company strongly recommend that all existing Drupal users upgrade to this new version immediately.
