 * The 'rados df' JSON output now prints numeric values as numbers instead of
   strings.
 
+* There was a bug introduced in Jewel (#19119) that broke the mapping behavior
+  when an "out" OSD that still existed in the CRUSH map was removed with 'osd rm'.
+  This could result in 'misdirected op' and other errors.  The bug is now fixed,
+  but the fix itself introduces the same risk because the behavior may vary between
+  clients and OSDs.  To avoid problems, please ensure that all OSDs are removed
+  from the CRUSH map before deleting them.  That is, be sure to do::
+
+     ceph osd crush rm osd.123
+
+  before::
+
+     ceph osd rm osd.123
