The entity team was busy: Nodes are using the new Entity API and Taxonomy Terms are not far behind. All the field types are also getting integrated with the new Entity API. Given that the new entity query only works with entities and fields integrating with this API, it's really great to see this happening.
CMI got a new override and context system. This, as usual, is only relevant to my goals as I am utterly dependent on the success of CMI :)
