As usual, we stay busy keeping our Drupal installation updated and secure.
We have just upgraded to Drupal 6.16, installing several securty updates to bring us up to date. Although security issues that the updates addressed have not affected our customers, it is our duty to our clients to keep everything up to date nonetheless.
We also upgraded MIME Mail, a module used with our easy to use Newsletter feature. This module has not changed very much in a year, yet a small problem was found. The module is now secure on all our systems.
By the way, if you are looking for Drupal hosting services, our service comes with most of our proprietary modules, at no extra charge! It is a great advantage that you won't find anywhere else.
