Subject:   HEADS UP: an IPv4-mapped IPv6 address off by default

Hi,

I've just committed to change an IPv4-mapped IPv6 address off by
default.
The existing applications may be affected this change.  The
applications which depend on an IPv4-mapped IPv6 address will become
listen only an IPv6 socket.
Apache2 is known having this problem.  You may need to specify the
Listen directive explicitly in your httpd.conf like as follows:

	Listen 0.0.0.0:80
	Listen [::]:80

If you still want to use an IPv4-mapped IPv6 address, please specify

	ipv6_ipv4mapping="YES"

in your /etc/rc.conf.

Sincerely,
