^^^^^^


Upgrade Notes
*************

* The default value of the configuration option,
  "glance_num_retries", has been changed to 3 in this release. Its
  former value was 0. The option controls how many times to retry a
  Glance API call in response to a HTTP connection failure, timeout or
  ServiceUnavailable status. By this change, Cinder can be more
  resilient to temporary failure and continue the request if a retry
  succeeds.


Bug Fixes
*********

* Bug #1887885 (https://bugs.launchpad.net/cinder/+bug/1887885): In
  NEC driver, fix a snapshot detach error.

* Bug #1887962 (https://bugs.launchpad.net/cinder/+bug/1887962):
  PowerMax driver fix to rectify incorrectly deleted non-temporary
  snapshots when calling do_sync_check used in multiple operations due
  to missing check for temporary snapshot name.

* Bug #1895510 (https://bugs.launchpad.net/cinder/+bug/1895510): IBM
  DS8K: Fixed compatability issue when using the IBM DS8K driver with
  storage version R9 and later.

* RBD driver Bug #1898918
  (https://bugs.launchpad.net/cinder/+bug/1898918): Fix thread block
  caused by the flatten operation during cloning a volume. Now the
  flatten operation is executed in a different thread.

* RBD driver bug #1901241
  (https://bugs.launchpad.net/cinder/+bug/1901241): Fixed an issue
  where decreasing the "rbd_max_clone_depth" configuration option
  would prevent volumes that had already exceeded that depth from
  being cloned.

* Bug #1904440 (https://bugs.launchpad.net/cinder/+bug/1904440):
  When an iSCSI/FC encrypted volume was cloned, the rekey operation
  would stamp the wrong encryption key on the newly cloned volume.
  This resulted in a volume that could not be attached.  It does not
  present a security problem.

* Bug #1883490 (https://bugs.launchpad.net/cinder/+bug/1883490):
  Fixed incorrect response of listing volumes with filters.
