At least if you ordered the pre-release…
My OpenBSD 4.1 CD set and T-shirts arrived today.
The lyrics and the 4.1 song (MP3 4.1MB / OGG 8.3MB) are already up.
The offical release will be at the beginning of May but you can order OpenBSD 4.1 today.
A list of changes between OpenBSD 4.0 and 4.1 can be found here. One very nice addition in my opinion is hoststated(8), a host status daemon that can be used with PF to manage load-balanced servers and remove servers from the pool if they do not serve a HTTP page or your specific monitor script fails.
This is a very interesting for people like me who use OpenBSD firewalls in front of Rails applications. With OpenBSD/PF/pfsync/hoststated you can very easily have redundant firewalls load-balance your Apaches and automatically exclude a host that is down for whatever reason.
