  The AOE protocol connector logic in os-brick is no longer needed and
  has now been removed.

* The ITRI DISCO driver was removed from Cinder in the Stein
  release. The connector logic in os-brick is no longer needed and has
  now been removed.

* The DRBD driver was removed from Cinder in the Stein release by
  the vendor. The connector logic in os-brick is no longer needed and
  has now been removed.

* The HGST driver was removed from Cinder in the Stein release. The
  connector logic in os-brick is no longer needed and has now been

  now been removed.


Bug Fixes
*********

* Bug #1823200 (https://bugs.launchpad.net/cinder/+bug/1823200):
  Prior fixes for this bug changed the connection properties but did
  not take into account an upgrade scenario in which currently
  attached volumes had the old format connection properties and could
  fail on detatch with "KeyError: 'config_group'".  This release
  updates the 'scaleio' connector to handle this situation.  It is
  only applicable to deployments using a Dell EMC PowerFlex/VxFlex
  OS/ScaleIO backend.

* [bug 1862433 (https://bugs.launchpad.net/os-brick/+bug/1862443)]
  Fix an issue where platform id is needed to determine  name of scsi
  disk.

* Bug #1865754 (https://bugs.launchpad.net/cinder/+bug/1865754): Fix
  to the rbd connector to work with Ceph Octopus (Version 15.2.0 and
  later). Octopus has slightly changed its requirements such that it
  now needs a "[global]" heading at the beginning of the "ini" config
  file that is generated within the "RBDConnector" class.  This
  release detects the Ceph version and supplies the appropriate config
  file.

* Improve WWN detection for arrays with multiple designators. (bug
  1881608).

* Improve iSCSI multipath detection to work even if we cannot find
  the volume's WWN in sysfs. (bug 1881619).

* Fix check_valid_path method in the RBD connector for locally
  attached volumes.  (Bug #1884552)

* Implement the extend_volume method for the RBD connector. (Bug
  #1884554).
