+v0.94.6 Hammer
+==============
+
+This Hammer point release fixes a range of bugs, most notably a fix
+for unbounded growth of the monitor's leveldb store, and a workaround
+in the OSD to keep most xattrs small enough to be stored inline in XFS
+inodes.
+
+We recommend that all hammer v0.94.x users upgrade.
+
+For more detailed information, see :download:`the complete changelog <changelog/v0.94.6.txt>`.

+v0.94.5 Hammer

+
+All v0.94.4 Hammer users are strongly encouraged to upgrade.
+
+Notable Changes
+---------------
+* librbd: potential assertion failure during cache read (`issue#13559 <http://tracker.ceph.com/issues/13559>`_, `pr#6348 <http://github.com/ceph/ceph/pull/6348>`_, Jason Dillaman)

+v0.94.4 Hammer
+==============
+
+This Hammer point release fixes several important bugs in Hammer, as well as
+fixing interoperability issues that are required before an upgrade to
+Infernalis. That is, all users of earlier version of Hammer or any
+version of Firefly will first need to upgrade to hammer v0.94.4 or
+later before upgrading to Infernalis (or future releases).
+
+All v0.94.x Hammer users are strongly encouraged to upgrade.

+v0.94.3 Hammer
+==============
+
+This Hammer point release fixes a critical (though rare) data
+corruption bug that could be triggered when logs are rotated via
+SIGHUP. It also fixes a range of other important bugs in the OSD,
+monitor, RGW, RGW, and CephFS.
+
+All v0.94.x Hammer users are strongly encouraged to upgrade.
+
+Upgrading
+---------
+
+* The ``pg ls-by-{pool,primary,osd}`` commands and ``pg ls`` now take
+ the argument ``recovering`` instead of ``recovery`` in order to
+ include the recovering pgs in the listed pgs.
