Now in -05 version:
     https://tools.ietf.org/html/draft-murchison-nntp-compress-05

If you have any comments, please don't hesitate to tell.


Changes since -04

    o  Reworded a sentence wrongly using "MAY NOT" (not a key word
       defined in [RFC2119]).

    o  Uppercased a "must" and a "should" in Section 3.1.

Changes since -03

    o  Added a naming convention for NNTP compression algorithms.
       Improve the wording of registered vs private compression
       algorithms.

    o  If a registered NNTP compression algorithm is advertised, it MUST
       fully conform with its related specification.

    o  Fixed the wording of security considerations to reflect that the
       threat appears when public and confidential data are compressed
       together inside a security layer.  Thanks to Angel Gonzalez for
       pointing that.

    o  The default configuration SHOULD be disabled compression when a
       security layer is active.

    o  COMPRESS acts as a compression layer, not a transport layer.

    o  Minor editorial changes.
