This is a major bugfix release for firefly, fixing a range of issues in the OSD and monitor, particularly with cache tiering. There are also important fixes in librados, with the watch/notify mechanism used by librbd, and in radosgw. A few pieces of new functionality of been backported, including improved 'ceph df' output (view amount of writeable space per pool), support for non-default cluster names when using sysvinit or systemd, and improved (and fixed) support for dmcrypt. We recommend that all v0.80.x Firefly users upgrade to this release.
