Since I last wrote about Tumblr Write your thoughts….or stream that news! there has been a new version released.

A write-up of the new features of Tumblr 3.0 at Read/Write web explains that it includes over 400 new features, fixes, and improvements. Beyond fixes, the features seem to cluster around four important themes for this release:

• Supporting Audio Posts
• Upgrades to Video Posting
• Private Communication: Channels
• Easier Integration Points (APIs)

Looking good!
