As of the meeting, we had all the intended features on the roadmap for this release sat ready and waiting to go. There are 7 major features in this release, which is a lot more than we expected to be packing for 0.5.2. All that's left now is to clean up the remaining bugs and blocker issues and we can push this out to the world.
