12.0.1
^^^^^^


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

* Add support to force detach a volume from all hosts on 3PAR.

* Adds support to configure the size of the native thread pool used
  by the cinder volume and backup services.  For the backup we use
  *backup_native_threads_pool_size* in the *[DEFAULT]* section, and
  for the backends we use *backend_native_threads_pool_size* in the
  driver section.


Bug Fixes
*********

* Dell EMC SC driver correctly returns initialize_connection data
  when more than one IQN is attached to a volume. This fixes some
  random Nova Live Migration failures where the connection information
  being returned was for an IQN other than the one for which it was
  being requested.

* We no longer leave orphaned chunks on the backup backend or leave
  a temporary volume/snapshot when aborting a backup.

* Resolve issue with cross AZ migrations and retypes where the
  destination volume kept the source volume's AZ, so we ended up with
  a volume where the AZ does not match the backend. (bug 1747949)

* When encryption keys based on the ConfKeyManager's fixed_key are
  migrated to Barbican, ConfKeyManager keys stored in the Backup table
  are included in the migration process. Fixes bug 1757235.

* Fixes concurrency issue on backups, where only 20 native threads
  could be concurrently be executed.  Now default will be 60, and can
  be changed with *backup_native_threads_pool_size*.

* RBD driver can have bottlenecks if too many slow operations are
  happening at the same time (for example many huge volume deletions),
  we can now use the *backend_native_threads_pool_size* option in the
  RBD driver section to resolve the issue.
