We welcome +and encourage any and all testing in non-production clusters to identify +any problems with functionality, stability, or performance before the +final Hammer release. + +We suggest some caution in one area: librbd. There is a lot of new +functionality around object maps and locking that is disabled by +default but may still affect stability for existing images. We are +continuing to shake out those bugs so that the final Hammer release +(probably v0.94) will be rock solid. + +Major features since Giant include: + +* cephfs: journal scavenger repair tool
