Our 0.2 release is an architectural release, where we focus on building Chandler as a platform. The 0.2 release was triggered by the clock as opposed to any functional or feature milestone. We want to show that we are making progress at regular intervals even though we might not have the loose ends all tidied up. We’re not trying to make this release look pretty. We will be moving the focus to end-user functionality and features next year, as described in the Product Roadmap and Chandler Timeline.

The 0.2 release of Chandler is still very skeletal in functionality, with very few obvious differences to the end-user from the 0.1 release. However, there are some major changes in the underlying framework and architecture. Our framework is by no means complete, but 0.2 shows a solid start on several of our major framework areas: Data Model and Repository,Notification Framework, Agent Framework, and the Chandler Presentation and Interaction Architecture (CPIA). We have also added enhanced debugging features.
