native IPv6 broken after 7.6.3 update

There is community threadand an explanation in the Apple Knowlege Baseabout the broken IPv6 tunnels in the new 7.6.3 version for Time Capsule/Airport devices. But the Native IPv6 is also broken on this version. I also needed to rollback to version 7.6.1.

The weird thing is that the configuration somehow ignored your settings and changed to the 6to4 prefix (described in RFC 3056).

Any forecast of when Apple will update this IPv6 broken release?

I wrote a some topic on my blogif you need more details.
