Clojure 1.2 Release

I'm pleased to announce today the release of Clojure 1.2.

For maven/leiningen users, your settings to get the beta from are:

:dependencies [[org.clojure/clojure "1.2.0"]
[org.clojure/clojure-contrib "1.2.0"]

This release includes many significant new features, such as protocols and datatypes; enhancements to existing features like the sequence library, destructuring and agents; support for annotations, etc. In addition, it incorporates many enhancements first developed and nurtured in clojure-contrib like I/O, string and pretty printing facilities.

This release reflects the work of many people in addition to myself, and I'd like to thank all of the contributors who've submitted fix and enhancement patches, and everyone in the community who has participated in terrific dialog that surrounds the development and use of Clojure.

Congrats and thanks to the contrib authors whose work has made it into the release:

Chas Emerick
Tom Faulhaber
Stephen Gilardi
Christophe Grand
Stuart Halloway
Chris Houser
David Liebke
Michel Salim
Stuart Sierra

I'd especially like to thank Stuart Halloway and the rest of the Clojure/core team for their tireless effort in authoring, screening and applying patches, setting up build machines, monitoring the mailing list, cutting releases etc. Their help greatly facilitates my ability to concentrate on the core design issues, and builds the foundation for increasing community involvement. A lot of work goes into Clojure. The team's effort is enabled and funded by the Clojure/core practice.

The full list of enhancements and changes is here:

and the fixed tickets are here:

What's next? Plenty! There are a few fixes and enhancements too impactful to squeeze into this release that we hope to get out there ASAP. I've done a ton of work already on enhanced primitive support and call linkage that will be moving into master. Design work is proceeding on many fronts. I'm looking forward to the increasing capability and maturity of Clojure, and the growth of the community.

Thanks to all involved!
