From the 'Contain This' files:

There is no single technology hotter today than Docker containers. Today the open-source Docker project released version 1.9.0 of Docker engine, providing an important milestone update.Docker

For me the biggest single item is the promotion of Docker Networking to stable from being just a technology preview. The libnetwork component in Docker first showed up in the 1.7 release cycle in June. Docker 1.8 which was released in August introduced Content Trust as its big marquee feature.

The full list of new networking features in Docker 1.9.0 includes:
