There's been a low-key beta of the latest Stack Exchange API revision, V2.1, under way for the last month or so.  I'm happy to announce that it's official, API V2.1 is public, frozen, and out the door.

About six months ago we began work in earnest on the second version of the Stack Exchange API.  A few months later, after a short private beta, we opened up a public beta with tantalizing prizes.

We've spent the last month polishing V2.0 of the Stack Exchange API in a public beta, and I'm happy to announce its final release.  Kudos to those who have reported bugs, and made quality suggestions during the beta.

More than a year and a half ago we unveiled the first version of the Stack Exchange API to the wider world.  Since then we've had a minor point release, improved app and script listing, and shared some statistics about the consumers of our API.
