3.1.  Principal Changes

     o The [RFC 2822] conventions for parenthesis-enclosed comments in
       headers are supported.
     o Whitespace is permitted in Newsgroups-headers, permitting folding
       of such headers. Indeed, all headers can now be folded.
     o An enhanced syntax for the Path-header enables the injection
       point of and the route taken by an article to be determined with
       certainty.
     o Large parts of MIME are recognized as an integral part of
       Netnews.
     o There is a new Control message 'mvgroup' to facilitate moving a
       group to a different place (name) in a hierarchy.
     o There is a new mandatory Injection-Date-header to facilitate the
       rejection of stale articles.
     o There are several new optional headers defined, notably Archive,
       Complaints-To, Injection-Info, Mail-Copies-To, Posted-And-Mailed
       and User-Agent, leading to increased functionality.
     o Provision has been made for almost all headers to have MIME-style
       parameters (to be ignored if not recognized), thus facilitating
       extension of those headers in future standards.
     o Certain headers and Control messages (a-Appendix A.3 and Appendix
       A.3) have been made obsolete.
     o Distributions are expected to be checked at the receiving end, as
       well as the sending end, of a relaying link.
     o There are numerous other small changes, clarifications and
       enhancements.
