what has started a long time ago with patches from various people, was
started, abandoned, resumed finally found an end.

I am happy to hereby announce that the multi-IPv4/v6/no-IP jails work
has been merged to 7-STABLE and thus can be used in FreeBSD 7 without
the need to maintain or apply patches from now on.

This also means that the updated jails will be included in 7.2 release.

This update gives you (short selection):
- zero, one or multi-IP jails.
- IPv4 and IPv6 support.
- cpuset support for jails.
- jail names and states to ease administration. 
- 32bit compat on 64bit, jail v1 compat, ..

You'll find a longer summary about all the new features and how to use
them in a posting from December (you should really read it):

Since the above posting, multiple PRs had been addressed and fixes include
- SIOCGIFADDR ioctl handling which fixes the "samba inside jails problem"
- no more arp and ndp information disclosure
- updated rc.conf framework (fully backward compatible in 7), see
   man 5 rc.conf and /etc/defaults/rc.conf.
- various documentation/man page updates
- ...

I'd like to thank everyone who had helped to make this possible!

If you like the work, mayhap even use it for your business, or just want
to support FreeBSD, you may want to visit
and help donating some money.

Enjoy your new jails!
(and don't try to escape - you sure won't succeed;)
