Previously, the openstack-neutron-vmware package did not include 'python-networking-vmware-nsx package' as a dependency. Both packages had to be manually installed for NSX integration with OpenStack Neutron.
With this update, python-networking-vmware-nsx is a dependency of the openstack-neutron-vmware package. As a result, all the needed components for NSX integration are obtained by installing openstack-neutron-vmware.
Note that openstack-neutron-vmware is expected to be deprecated in a future release, with NSX components moving to python-networking-vmware-nsx.
