Open Stack

We are jubilant to announce the release of:

neutron 8.1.0: OpenStack Networking

This release is part of the mitaka stable release series.

For more details, please see below.

8.1.0
^^^^^

Support configuration of greenthreads pool for WSGI.

Several NICs per physical network can be used with SR-IOV.


Bug Fixes
*********

* The 'physical_device_mappings' of sriov_nic configuration now can
  accept more than one NIC per physical network. For example, if
  'physnet2' is connected to enp1s0f0 and enp1s0f1,
  'physnet2:enp1s0f0,physnet2:enp1s0f1' will be a valid option.


Other Notes
***********

* Operators may want to tune the "max_overflow" and
  "wsgi_default_pool_size" configuration options according to the
  investigations outlined in this mailing list post
  (http://lists.openstack.org/pipermail/openstack-
  dev/2015-December/082717.html). The default value of
  "wsgi_default_pool_size" inherits from that of oslo.config, which is
  currently 100.  This is a change in default from the previous
  Neutron-specific value of 1000.
