Melanie Witt and Eric Fried talk about what’s new in this release and what to expect from the next one.


At the recent Open Infrastructure Summit in Denver, project team leads (PTLs) and core team members offered updates for the OpenStack projects they manage, what’s new for this release and what to expect for the next one, plus how you can get involved and influence the roadmap.

Superuser features summaries of the videos; you can also catch them on the OpenStack Foundation YouTube channel.


Nova, OpenStack’s compute service.
