Today Six Apart released verson 3.16 of Movable Type. They have fixed many bugs and added many improvements to the user interface, there are over 100 changes!. Highlights include:

• Support for Creative Commons 2.0 licenses
• Easier dynamic publishing setup
• Subcategories are now displayed hierarchically in the user interface
• Better error checking and data validation
• Includes a new open-source version of the ‘nofollow’ plugin

It looks like it will be a simple upgrade if you are running a recent version. I’ll be giving it a try later today.

There is a full changelog in their ProNet section (so you need to register to read it), and a list of known issues in version 3.16 (which anyone can read).
