Oh so thats why thunderbird broke under my highwinds-omicron-Greg Lyda 
Inc. account

Thats true, so yes defining it like this could be very dangerous.

All the big tools to download binaries are open source can easily 
support asking for 64 bit article numbers (they download by MID anyway, 
so woudlnt be an issue).

I agree with what Julien or someone said about adding a LARGEGROUP 
capability instead of assuming it under Version 3.

    Pretty easy to test.
    Just done with a dummy news server, and Thunderbird Version 68.7.0 (64
    bit) released on April 8th, 2020.

    By hand:

    % telnet localhost 50300
    200 Testing server
    CAPABILITIES
    101 Capability list:
    VERSION 2 3
    LIST ACTIVE
    READER
    .
    LIST
    215 Newsgroups in form "group high low status"
    trigofacile.test 9000000000000000000 9000000000000000000 y
    .
    QUIT




    I configure Thunderbird to access this dummy news server.

    200 Testing server
    MODE READER
    200 Reader mode
    LIST
    215 Newsgroups in form "group high low status"
    trigofacile.test 9000000000000000000 9000000000000000000 y
    .
    GROUP trigofacile.test
    211 1 9000000000000000000 9000000000000000000 trigofacile.test

    [Thunderbird then just hangs.]


    I change article numbers, and retest:

    200 Testing server
    MODE READER
    200 Reader mode
    GROUP trigofacile.test
    211 1 900 900 trigofacile.test
    XOVER 900-900
    500 What?
    HEAD 900
    500 What?

    (I have not implemented responses to XOVER and HEAD. Thunderbird looks
    fine, though, with article number 900.)



    Another test:

    200 Testing server
    MODE READER
    200 Reader mode
    GROUP trigofacile.test
    211 1 2147483648 2147483648 trigofacile.test

    [Thunderbird then just hangs.]



    And last test:

    200 Testing server
    MODE READER
    200 Reader mode
    GROUP trigofacile.test
    211 1 2147483647 2147483647 trigofacile.test
    XOVER 2147483647-2147483647
    500 What?
    HEAD 2147483647
    500 What?


    So, 2^31-1 works fine, but above not.

    There is really interoperability problem with current news readers (in
    2020), so defining VERSION 3 of NNTP like this is very dangerous.
