I released 3.2.0 beta 4 for A6 and C6 (along with C5x/C5c). Release notes are here:
Main things are DHCP Option 82 for IPv4 and DHCP options for IPv6.
Please keep in mind you need to keep IPv6 and DHCPv6 enabled on the br0 interface of the A6 and C6x to keep all data populated on the Wireless Statistics screen and I believe for VLANs to function correctly as well. This will be corrected in the next beta.
