v0.71
~~~~~
* The MDS now disallows snapshots by default as they are not
considered stable. The command 'ceph mds set allow_snaps' will
enable them.
* For clusters that were created before v0.44 (pre-argonaut, Spring
2012) and store radosgw data, the auto-upgrade from TMAP to OMAP
objects has been disabled. Before upgrading, make sure that any
buckets created on pre-argonaut releases have been modified (e.g.,
by PUTing and then DELETEing an object from each bucket). Any
cluster created with argonaut (v0.48) or a later release or not
using radosgw never relied on the automatic conversion and is not
affected by this change.
* Any direct users of the 'tmap' portion of the librados API should be
aware that the automatic tmap -> omap conversion functionality has
been removed.
* Most output that used K or KB (e.g., for kilobyte) now uses a
lower-case k to match the official SI convention. Any scripts that
parse output and check for an upper-case K will need to be modified.
v0.72
~~~~~
* ceph-fuse and radosgw now use the same default values for the admin
socket and log file paths that the other daemons (ceph-osd,
ceph-mon, etc.) do. If you run these daemons as non-root, you may
need to adjust your ceph.conf to disable these options or to adjust
the permissions on /var/run/ceph and /var/log/ceph.
