-* The meaning of 'osd scrub max interval' has been changed: it is now
-  the amount of time after which a PG will be scrubbed regardless of
-  the system load.  The option 'osd scrub min interval' now has the
-  previous meaning: the amount of time before a PG is scrubbed if the
-  load is low.  The defaults have been adjusted such that the only
-  change in behavior is that PGs will now be scrubbed after a week
-  even if the system load remains high.  However, if either of these
-  options have been changed in ceph.conf, those settings should be
-  reviewed in light of their adjusted meanings.
-
-* The 'ceph osd pool delete <poolname>' and 'rados rmpool <poolname>'
-  now have safety interlocks with loud warnings that make you confirm
-  pool removal.  Any scripts that rely on these functions zapping data
-  without confirmation need to be adjusted accordingly.
-
-* ceph-mon now requires the creation of its data directory prior to
-  --mkfs, similarly to what happens on ceph-osd.  This directory is
-  no longer automatically created, and custom scripts should be
-  adjusted to reflect just that.

  Release Notes
 ===============
 
+v0.59
+-----
+
+Upgrading
+~~~~~~~~~
+
+* The monitor is using a completely new storage strategy and
+  intra-cluster protocol.  This means that v0.59 and pre-v0.59
+  monitors do not talk to each other.  When you upgrade each one, it
+  will convert its local data store to the new format.  Once you
+  upgrade a majority, the quorum will be formed using the new protocol
+  and the old monitors will be blocked out until they too get
+  upgraded.  For this reason, we recommend not running a mixed-version
+  cluster for very long.
+
+* ceph-mon now requires the creation of its data directory prior to
+  --mkfs, similarly to what happens on ceph-osd.  This directory is no
+  longer automatically created, and custom scripts should be adjusted to
+  reflect just that.
+
+
