I'm not sure where to report this to, but I have Core 69 running on a Xen HVM, using Debian Wheezy, Xen 4.1 and the xl toolstack. It is doing a site-to-site vpn, some road warriors, and runs dhcp and NAT.
This was an upgrade from Core 68.
Please let me know where reports should be made in the future as I have a couple of other routers to upgrade.
