If you haven't heard yet, Movable Type 3.16 has been released. Lots of various bug fixes and subtle enhancements in this one. Be sure to upgrade. If you're not running 3.x yet, you're missing out.
To celebrate the occasion, I've created a new logo for the app.
It matches the MT graphics on the newly designed Six Apart web site. To install it, just download the image above and copy it into Movable Type's "images" directory. You can backup the original one first if you ever want to switch back.
