Big Pile of Drupal Updates

The Drupal Security Team has apparently been working overtime as a slug of new Drupal updates appeared last night.  This includes two (count 'em, two) different new versions of Drupal, and many module updates, all intended to fix security issues.  Drupal 6.18 is a security-only update which fixes security holes and nothing more. 

6.19 on the other hand fixes the security issues and a few other bugs.  We're at the moment trying to sort through all of these updates and figure out which go where for our maintenance customers.  In the meantime, you really ought to be looking seriously at updating your sites at least to 6.18 since the security issues are fairly serious.
