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!

Yup, the dynamic reservations are going to hopefully make it into the next release 0.23. Really excited to use this for data stores such as Kafka, Cassandra, Postgres, etc.
