+Known Issues with v10.1.0
+-------------------------
+
+ * While running a mixed version cluster of jewel and infernalis or
+   hammer monitors, any MDSMap updates will cause the pre-jewel
+   monitors to crash.  Workaround is to simply upgrde all monitors.
+   There is a fix but it is still being tested.
+
+ * Some of the rbd-mirror functionality for switching between active
+   and replica images is not yet merged.
