CentOS - Sep 2009 - New sshd_config - what has changed?

I see that there is a new sshd_config in the latest updates.

Since I have altered the original file, this one got installed as .rpmnew

It has two changes:

 > #AddressFamily any

So does this make it default to IPv4 only?

 > #ChrootDirectory none


Chroot is now an option for SSH?

See "man sshd_config"

#AddressFamily any
Valid arguments are 'any', 'inet' (use IPv4 only) or
'inet6' (use IPv6 only)

#ChrootDirectory none
Specifies a path to chroot to after authentication.

Perviously this was uncommented, so now it is running on the default...

This line was not even present before.  So it is still running on the 
default.  But since it was added, is this a new option?

Depending upon the version of OpenSSH ( I built OpenSSH 5.2p1 from
source) I ended up having to set

      AddressFamily inet

in order to use IPV4 and X11 forwarding - presumably to avoid IPV6
high jacking of the X11 connection.
