The new features are really exciting. Disk quota isolation is important to pave the way for stateful workloads, and with the upcoming work on stateful primitives (https://issues.apache.org/jira/browse/MESOS-2018) it will be easy to run things like databases and filesystems.

The service discovery metadata and labels allow more control over the visibility and naming of tasks. Mesos DNS (https://github.com/mesosphere/mesos-dns) will get support shortly.

Finally the modules also got some additions: hooks and anonymous modules, which can be used to add arbitrary extensions to Mesos.

Exciting release!
