5.0.0
^^^^^


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

* NVMe-OF connector: Added support for storage systems presenting
  multiple volumes within one NVMe subsystem.


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

* A workaround for Bug #1633518
  (https://bugs.launchpad.net/cinder/+bug/1633518), where mangled
  passwords were used for various encryptors, has been removed. This
  was first introduced way back in the 1.9.0 Ocata-era release and has
  had more than enough time to bed in.


Bug Fixes
*********

* LVM driver bug #1901783
  (https://bugs.launchpad.net/cinder/+bug/1901783): Fix unexpected
  delete volume failure due to unexpected exit code 139 on "lvs"
  command call.

* NVMe-oF connector bug #1928944 (https://bugs.launchpad.net/os-
  brick/+bug/1928944): Fixed not returning the right nqn value on
  "get_connector_properties" when "/etc/nvme/hostnqn" doesn't exist.
