We are pleased to announce Chandler 0.3! Our architecture is finally stable enough to start developing end-user features.

Release 0.3 targets developers who want an early preview into our architecture as we are developing it. With this release we now can begin to encourage open source developers to work with the OSAF core development team, as in the upcoming PyCon Sprint.

New in Release 0.3 The two biggest architecture advancements in this release are the Repository and the Chandler Presentation and Interaction Architecture (CPIA). In 0.3, our Repository is much more robust and scalable, and now implements a transaction and threading model. This release also marks the debut of CPIA, which is a UI layer in our architecture that is uniquely adapted for item-centric applications based on our Repository. Not only does it abstract away implementation-specific UI widgets, but CPIA elements have direct access to our Repository via data-driven queries.
