WordPress 3.1 Features Taking Shape

Development on WordPress 3.1 is well underway, and with the string freeze coming up on December 1st, some key new features are beginning to take shape. Earlier this week, Automattic code wrangler Stephane Daury published a revealing screenshot of the new internal linking feature, while WordPress lead developer Mark Jaquith briefly discussed the new post formats feature. What do you think of the internal linking and post formats features thus far? Will you be trying the 3.1 beta when it’s released later this month?
