I’m still rocking the 3.2 Beta (now version 2), and WordPress have also just announced 3.1.3 of plain vanilla WordPress, which is mostly geared towards various security enhancements.

- Google Chrome Frame is now supported in the admin, if you have it installed. This is especially useful for IE 6 users (remember, IE 6 is otherwise deprecated for the admin).
- The admin is less ugly in IE 7.
- The blue admin color scheme has caught up to the grey one, and is ready for testing.
