I was surprised to learn last week that RFC 2822 has been made obsolete by RFC 5322, and 2821 by 5321. I think that the major changes wre to clear up sections where there were differences of interpretation.

I saw the update/obsoletion via http://twitter.com/rfc

I was a subscriber to the DRUMS mailing list when that group was revising RFCs 821 and 822 to produce 2821 and 2822. I do not remember having unsubscribed from that list, but I have seen no activity on that list after 2821 and 2822 were issued. So, revisions to those two RFCs caught me by surprise.
