5.1.0
^^^^^


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

* Services using os-brick need to set the "lock_path" configuration
  option in their "[oslo_concurrency]" section since it doesn't have a
  valid default (related bug #1947370
  (https://bugs.launchpad.net/cinder/+bug/1947370)).


Bug Fixes
*********

* Bug #1944474 (https://bugs.launchpad.net/os-brick/+bug/1944474):
  Fixed missing retries to reinitiate iSCSI connections with high
  concurrency of connections and with multipath enabled.

* NVMe-oF connector bug #1945323 (https://bugs.launchpad.net/os-
  brick/+bug/1945323) [bugs.launchpad.net]: Fixed a regression where
  connect_volume returned a list with a single path instead of just
  the path

* Bug #1947370 (https://bugs.launchpad.net/cinder/+bug/1947370):
  Fixed race conditions on iSCSI with shared targets and NVMe
  "connect_volume" and "disconnect_volume" calls.
