17.4.0
^^^^^^


New Features
************

* Log a warning from the volume service when a volume driver's
  get_volume_stats() call takes a long time to return.  This can help
  deployers troubleshoot a cinder-volume service misbehaving due to a
  driver/backend performance issue.


Bug Fixes
*********

* Fixed the schema validation for attachment create API to make
  instance uuid an optional field. It had mistakenly been defined as a
  required field when schema validation was added in an earlier
  release. Also updated the schema to allow specification of the
  "mode" parameter, which has been available since microversion >=
  3.54, but which was not recognized as a legitimate request field.

* Bug #1924643 (https://bugs.launchpad.net/cinder/+bug/1924643):
  Fixed the NetApp cinder driver sub-clone operation that might be
  used by extend operation in case the extended size is greater than
  the max LUN geometry.
