Here are some initial FreeBSD ports/packages for the server-2.4.2 and client-2.4.1.0 betas. They both launch in a 12.0-RELEASE jail that has both ipv4 and ipv6 addresses, and I can reach the web interface for the server via both the ipv4 and ipv6 addresses.
IPv6 is more functional, but not completely yet. I think a client issue.
I can use the administration interface over IPv6 and add hosts and everything. The URL and hostname-checks do not allow IPv6-addresses yet.
When installing a client with and internet hostname via /etc/hosts with only an IPv6 address, the client is unable to connect, although the server is listening on the IPv6 socket.

Have tried through 2.4.2 update but still getting timeout (2) errors preventing file and image backups on several sets, so have rolled back to 2.3.8 and backups running well again, even with 2.4.0 clients. Will try again later in development cycle.
Windows Server 2008 r2 with Windows 7 Pro clients on AD domain.
Tried 2.4.2 server again on FreeNAS. Compiled fine. Backups from clients work fine but GUI is not accessible through usual IPV4 address. Again : any clue ?
