OpenNebula 5.6 (Blue Flash) is the fourth major release of the OpenNebula 5 series. A significant effort has been applied in this release to enhance features introduced in 5.4 Medusa, while keeping an eye in implementing those features more demanded by the community. A massive set of improvements happened at the core level to increase robustness and scalability, and a major refactor happened in the vCenter integration, particularly in the import process, which has been streamlined. Virtually every component of OpenNebula has been reviewed to target usability and functional improvements, trying to keep API changes to a minimum to avoid disrupting ecosystem components.
Following our tradition this OpenNebula release is named after NGC 6905, also known as the Blue Flash Nebula, a planetary nebula in the constellation Delphinus. It was discovered by William Herschel in 1784.
The OpenNebula team is now set to bug-fixing mode. Note that this is a RC release aimed at testers and developers to try the new features, and send a more than welcomed feedback for the final release. Note that being a RC there is no migration path from the previous stable version (5.4.13) nor migration path to the final stable version (5.6.0).
The OpenNebula project would like to thank the community members and users who have contributed to this software release by being active with the discussions, answering user questions, or providing patches for bugfixes, features and documentation.
