Joomla! 1.6.4 is out! Aside fixing several security issues, the new release will provide an automatic upgrade to the upcoming Joomla! 1.7.
RSFirewall! has been updated with Joomla! 1.6.4 hash files as well.
If you're using 1.6 on a live site, we recommend updating both Joomla! and RSFirewall! to the latest revisions (Joomla! 1.6.4, respective RSFirewall! rev. 26) and perform a new "System Check".
