We've just recently pushed an update to Oracle OpenStack for Oracle Solaris. Supported customers who have access to the Support Repository Updates (SRU) can upgrade their OpenStack environments to the Juno release with the availability of SRU 18.104.22.168.0 onwards.
The Juno release includes a number of new features, and in general offers a more polished cloud experience for users and administrators. We've written a document that covers the upgrade from Havana to Juno for those on SRU 10.5 and SRU 11.5. The process to upgrade involves some manual administrator to copy and merge OpenStack configuration across the two releases, and upgrade the database schemas that the various services use. We've worked hard to provide a seamless automatic upgrade - this is now available from Oracle Solaris 11.2 SRU 12.5 onwards!
