This is the fifth release candidate for Luminous, the next long term stable release. We’ve had to do this release as there was a bug in the previous RC, which affected upgrades to Luminous.[1]

In particular, this will fix things for those of you who upgraded from Jewel or a previous RC and saw OSDs crash instantly on boot. We had an oversight in dealing with another bug. (Standard disclaimer: this was a logic error that resulted in no data changes. There were no durability implications — not that that helps much when you can't read your data out again.) Sorry guys! -Greg

Please note that this is still a *release candidate* and not the final release, we're expecting the final Luminous release in a week's time, meanwhile, testing and feedback is very much welcom.

Ceph Luminous (v12.2.0) will be the foundation for the next long-term stable release series. There have been major changes since Kraken (v11.2.z) and Jewel (v10.2.z), and the upgrade process is non-trivial. Please read these release notes carefully. Full details and changelog at http://ceph.com/releases/v12-1-4-luminous-rc-released/
