Noteworthy for DPDK application developers is that upstream deprecated the old mechanism of a combined shared library. libdpdk.so is now a linker script referring to the - individually packaged - sub-libraries librte-*. Furthermore the DPDK related kernel modules are now provided as dkms based packages.
Libvirt has been updated to version 2.1. See the Changelogs for details.
In order to reduce the Debian delta, the main libvirt service has been renamed to libvirtd.service. libvirt-bin.service becomes an alias to maintain backwards compatibility.
Open vSwitch has been updated to the latest release, 2.6.
See the Open vSwitch News for mroe details.
The enablement of openvswitch-switch-dpdk has changed upstream. So if you are upgrading from a previously dpdk enabled configuration then you will need to update your enablement appropriately. See associated Readme at /usr/share/doc/openvswitch-switch-dpdk/README.Debian for details.

New network management features have been added to LXD, allowing the creation and management of bridges, DHCP settings, tunnels, ... More information can be found from "lxc network help" and in the upstream documentation.
