^^^^^^


Bug Fixes
*********

* Bug #1953168 (https://bugs.launchpad.net/cinder/+bug/1953168):
  Fixed missing parameter in the capacity filter log message.

* Infinidat Driver bug #1981354
  (https://bugs.launchpad.net/cinder/+bug/1981354): Fixed Infinidat
  driver to return all configured and enabled iSCSI portals for a
  given network space.

* PowerMax driver bug #1979668
  (https://bugs.launchpad.net/cinder/+bug/1979668): Fixed visibility
  of manageable volumes in multiple storage groups.

* PowerStore driver bug #1981068
  (https://bugs.launchpad.net/cinder/+bug/1981068): Fixed request data
  validation for the REST client.

* Bug #2008259 (https://bugs.launchpad.net/cinder/+bug/2008259):
  Fixed the volume create functionality where non-admin users were
  able to create multiattach volumes by providing the *multiattach*
  parameter in the request body. Now we can only create multiattach
  volumes using a multiattach volume type, which is also the
  recommended way.


Other Notes
***********

* Removed the ability to create multiattach volumes by specifying
  *multiattach* parameter in the request body of a volume create
  operation. This functionality is unsafe, can lead to data loss, and
  has been deprecated since the Queens release. The recommended method
  for creating a multiattach volume is to use a volume type that
  supports multiattach.  By default, volume types can only be created
  by the operator.  Users who have a need for multiattach volumes
  should contact their operator if a suitable volume type is not
  available.

* Unified how cinder calculates the virtual free storage space for a
  pool. Previously Cinder had 2 different mechanisms for calculating
  the virtual free storage.  Now both the Capacity Filter and the
  Capacity Weigher use the same mechanism, which is based upon the
  defined terms in https://specs.openstack.org/openstack/cinder-
  specs/specs/queens/provisioning-improvements.html
