6.0.0
^^^^^


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

* Specific location for os-brick file locks using the "lock_path"
  configuration option in the "os_brick" configuration group.
  Previously, os-brick used the consuming service's lock_path for its
  locks, but there are some deployment configurations (for example,
  Nova and Cinder collocated on the same host) where this would result
  in anomalous behavior.  Default is to use the consuming service's
  lock_path.

  This change requires a consuming service to call the
  "os_brick.setup" method after service configuration options have
  been called.

* Phase 1 (Native) implementation of NVMeoF Multipathing. See the
  NVMeoF Multipathing (https://specs.openstack.org/openstack/cinder-
  specs/specs/yoga/nvme-multipath.html) spec for details.


Upgrade Notes
*************

* Python 3.6 & 3.7 support has been dropped. The minimum version of
  Python now supported is Python 3.8.

* To use the os-brick specific file lock location introduced in this
  release, an external service using the library must call the
  "os_brick.setup" method.

* No longer using "systool" to gather FC HBA information, so the
  "sysfsutils" package is no longer needed.


Bug Fixes
*********

* Bug #1888675 (https://bugs.launchpad.net/os-brick/+bug/1888675):
  Fixed in-use volume resize issues caused by the multipath-tools
  version.

* NVMe-oF connector bug #1964379 (https://bugs.launchpad.net/os-
  brick/+bug/1964379): Fixed using non LUKS v1 encrypted volumes, as
  once one of such volumes is disconnected from a host all successive
  NVMe-oF attachments would fail.

* Bug #1967790 (https://bugs.launchpad.net/os-brick/+bug/1967790):
  Fixed encryptor's connect_volume returns and the symlink is pointing
  to the raw block device instead of to the decrypted device mapper
  device.

* NVMe-oF connector bug #1964389 (https://bugs.launchpad.net/os-
  brick/+bug/1964389): Fixed showing misleading traceback.

* RBD connector bug #1981455
  (https://bugs.launchpad.net/cinder/+bug/1981455): Fixed
  AttributeError error on disconnect for RBD encrypted volumes not
  using host attachments.
