  Release Notes
 ===============
 
+v0.76 (frozen, not yet released)
+--------------------------------
+
+This release includes another batch of updates for firefly
+functionality.  Most notably, the cache pool infrastructure now
+support snapshots, the OSD backfill functionality has been generalized
+to include multiple targets (necessary for the coming erasure pools),
+and there were performance improvements to the erasure code plugin on
+capable processors.  The MDS now properly utilizes (and seamlessly
+migrates to) the OSD key/value interface (aka omap) for storing directory
+objects.  There continue to be many other fixes and improvements for
+usability and code portability across the tree.
+
+Upgrading
+~~~~~~~~~
+
+* 'rbd ls' on a pool which never held rbd images now exits with code
+  0. It outputs nothing in plain format, or an empty list in
+  non-plain format. This is consistent with the behavior for a pool
+  which used to hold images, but contains none. Scripts relying on
+  this behavior should be updated.
+
+* The MDS requires a new OSD operation TMAP2OMAP, added in this release.  When
+  upgrading, be sure to upgrade and restart the ceph-osd daemons before the
+  ceph-mds daemon.  The MDS will refuse to start if any up OSDs do not support
+  the new feature.
+
+* The 'ceph mds set_max_mds N' command is now deprecated in favor of
+  'ceph mds set max_mds N'.
+
