The document summarizes updates to OpenStack Glance from the Kilo to Liberty releases. In Kilo, Glance added features like artifact repository, catalog indexing, image conversion/introspection, and support for multiple datastores in storage drivers. Liberty priorities included additional image listing filters, store refactor/cleaner API, encrypted/authenticated image support, and tag metadata CLI support. It also focused on Glance v3 API evolution and increasing adoption of the v2 API within OpenStack. The presenter invites questions by IRC, email, the OpenStack mailing list tagged [Glance], or the weekly Glance meeting.
