LXD 2.3 release announcement

27th of September 2016
LXD 2.3 includes a few major features we've been working on for months.

The main one is a completely new set of API endpoints, configuration options and commands.
This allows creating and configuring bridges through LXD, including IPv4
and IPv6 connectivity, Ubuntu FAN support, cross-host tunnels with GRE
or VXLAN, various DNS modes, DHCP configuration and MAC filtering.

The other feature we're very excited about is support for AppArmor
namespaces and stacking. This will allow containers to load apparmor
profiles and further confine their workloads.
