19.2.0
^^^^^^

Bug Fixes

* The Compute service has never supported direct booting of an
  instance from an image that was created by the Block Storage service
  from an encrypted volume.  Previously, this operation would result
  in an ACTIVE instance that was unusable.  Beginning with this
  release, an attempt to boot from such an image will result in the
  Compute API returning a 400 (Bad Request) response.

* A new config option "[neutron]http_retries" is added which
  defaults to 3. It controls how many times to retry a Neutron API
  call in response to a HTTP connection failure. An example scenario
  where it will help is when a deployment is using HAProxy and
  connections get closed after idle time. If an incoming request tries
  to re-use a connection that is simultaneously being torn down, a
  HTTP connection failure will occur and previously Nova would fail
  the entire request. With retries, Nova can be more resilient in this
  scenario and continue the request if a retry succeeds. Refer to
  https://launchpad.net/bugs/1866937 for more details.
