Cliff Hall has released a new version of PureMVC with various improvements which you can read about here. In conjunction with this release, Cliff has also unveiled the Manifold Project, which provides numerous demos and ports of PureMVC to languages other than ActionScript 3. I am proud to say that I am participating in the open-source Manifold Project, and my Flex-on-Rails application, “Index Cards,” is now a Manifold demo application. From this point forward, you can keep abreast of the development of Index Cards, report bugs, and suggest new features via its Manifold project site.

Kudos to Cliff, who had to do a tremendous amount of work to pull this off. I suspect that a lot of developers will benefit from the effort.
