 * RADOS: `get_pool_is_selfmanaged_snaps_mode` C++ API has been deprecated
   due to being prone to false negative results.  It's safer replacement is
   `pool_is_in_selfmanaged_snaps_mode`.
+* RADOS: For bug 62338 (https://tracker.ceph.com/issues/62338), we did not choose
+  to condition the fix on a server flag in order to simplify backporting.  As
+  a result, in rare cases it may be possible for a PG to flip between two acting
+  sets while an upgrade to a version with the fix is in progress.  If you observe
+  this behavior, you should be able to work around it by completing the upgrade or
+  by disabling async recovery by setting osd_async_recovery_min_cost to a very
+  large value on all OSDs until the upgrade is complete:
+  ``ceph config set osd osd_async_recovery_min_cost 1099511627776``
