15.2.0
^^^^^^


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

* A new configuration option "http_retries" was added. This option
  allows configuring the number of times the nova or ironic client
  should retry on a failed HTTP call.

* Add new configuration option "igmp_snooping_enable". New option is
  in "OVS" config section and is used by openvswitch agent. This
  option is used to enable support for Internet Group Management
  Protocol (IGMP) in integration bridge.


Bug Fixes
*********

* 1875981 (https://bugs.launchpad.net/neutron/+bug/1875981) Neutron
  now correctly removes associated DNS records when an admin deletes
  ports, servers or floation IPs.
