16.4.0
^^^^^^

Bug Fixes

* Bug #1915800 (https://bugs.launchpad.net/cinder/+bug/1915800): Add
  support for ports filtering in XtremIO driver.

* Bug #1904892 (https://bugs.launchpad.net/cinder/+bug/1904892): Fix
  cinder manage operations for NFS backends using IPv6 addresses in
  the NFS server address.  These were previously rejected by the
  Cinder API.

* RBD driver bug #1907964
  (https://bugs.launchpad.net/cinder/+bug/1907964): Add support for
  fast-diff on backup images stored in Ceph. Provided fast-diff is
  supported by the backend it will automatically be enabled and used.
  With fast-diff enabled, the generation of diffs between images and
  snapshots as well as determining the actual data usage of a snapshot
  is speed up significantly.

* Bug #1920237 (https://bugs.launchpad.net/cinder/+bug/1920237): The
  backup manager calls volume remove_export() but does not wait for it
  to complete when detaching a volume after backup.  This caused
  problems when a subsequent operation started on that volume before
  it had fully detached.

* Pure Storage FlashArray driver fix to ensure cinder_tempest_plugin
  consistency group tests pass.
