Message-ID: <20210611093614.GA11264@dcvr> MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Disposition: inline List-Id: I'm wondering which and how wide support of RFC 3977 is amongst NNTP clients. The older RFC 977 seems more widely-implemented and the differences are minor enough that 977 clients can work on 3977 servers without problems. One thing I noticed is our handling of "GROUP" is more in line with RFC 977 where we return the min and max article number of the group. In contrast, RFC 3977 stipulates using low and high water marks (which account for deleted articles). It's a minor difference, I guess... Fwiw, RFC 3977 came about in 2006 when NNTP was already on a decline. I think my ISP stopped providing NNTP access around that time, too. So I suspect NNTP clients/libraries largely ignored 3977 and continued supporting the older 977.
