We are amped to announce the release of:
neutron 16.1.0: OpenStack Networking
This release is part of the ussuri stable release series.

Please report issues through:

For more details, please see below.
16.1.0 ^^^^^^
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.
* "DVR" routers now support "flat" networks.
* Added support for router availability zones in OVN. The OVN driver can now read from the router's availability_zone_hints field and schedule router ports accordingly with the given availability zones.
Deprecation Notes *****************
* Abstract method "plug_new" from the neutron.agent.linux.interface.LinuxInterfaceDriver class now accepts an optional parameter "link_up". Usage of this method, which takes from 5 to 9 positional arguments, without "link_up" is now deprecated and will not be possible starting in the W release. Third-party drivers which inherit from this base class should update the implementation of their "plug_new" method.
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.
* Fixed bug 1876092 (https://bugs.launchpad.net/neutron/+bug/1876092) which caused DUP ICMP replies on the "flat" networks used with "DVR" routers.
* Fixed an issue where the client on a dual-stack (IPv4 + IPv6) network failed to get configuration from the dnsmasq DHCP server. See bug: 1876094 (https://launchpad.net/bugs/1876094).
