  Release Notes
 ===============
 
+v0.81
+=====
+
+This is the first development release since Firefly.  It includes a
+lot of work that we delayed merging while stabilizing things.  Lots of
+new functionality, as well as several fixes that are baking a bit before
+getting backported.
+
+Upgrading
+---------
+
+* CephFS support for the legacy anchor table has finally been removed.
+  Users with file systems created before firefly should ensure that inodes
+  with multiple hard links are modified *prior* to the upgrade to ensure that
+  the backtraces are written properly.  For example::
+
+    sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
+
+* Disallow nonsensical 'tier cache-mode' transitions.  From this point
+  onward, 'writeback' can only transition to 'forward' and 'forward'
+  can transition to 1) 'writeback' if there are dirty objects, or 2) any if
+  there are no dirty objects.
