The successor to the Kilo release of the OpenStack open source cloud computing platform, OpenStack Liberty made its debut on October 15, 2015 as the twelfth major release of OpenStack. Liberty arrived as the second major update in 2015 for OpenStack, following Kilo’s release on April 30.
As with previous OpenStack releases, Liberty takes its name from a nearby city or distinguishing feature relative to the OpenStack design summit corresponding to each OpenStack release. In this case, Liberty is a village in the Canadian province of Saskatchewan.
Feature Enhancements in OpenStack Liberty
Liberty marks the first OpenStack release under the “Big Tent” model, and as a result it includes more OpenStack projects as part of the coordinated release than ever before, including a SearchLight search project that utilizes open-source ElasticSearch technology to enable users to query across an OpenStack deployment, Zaqar messaging, Barbican key manager, Manila shared file system and Designate DNS services.
The core projects in OpenStack received enhancements and new features in Liberty as well, including Cells version 2 in the Nova compute project, federated identity enhancements in the Keystone identity project, and a new component in the Neutron networking project called Courier that focuses on container networking.
The follow-up to OpenStack Liberty, OpenStack Mitaka, made its debut on April 7th, 2016, with the fourteenth OpenStack release, OpenStack Newton, expected in October 2016.
