The Minor version is an artifact from the DECSYSTEM-20 versioning

The Edit number is sequential, always goes up, but there can be gaps.
For example there might be many edits between releases.

DOCUMENTATION:
"Using C-Kermit" by Frank da Cruz and Christine M. Gianone,
Digital Press / Butterworth-Heinemann, Woburn MA, USA.
Second edition (1997), ISBN 1-55558-164-1.
Plus updates on the Kermit website:
http://www.kermitproject.org/ck90.html#doc
For Kermit 95, also:
"Kermit 95" by Christine M. Gianone and Frank da Cruz,
Manning Publications, Greenwich CT, USA (1998) - Online here:
http://www.kermitproject.org/k95manual/
ACKNOWLEDGMENTS:
The Kermit file transfer protocol was developed at the Columbia University
Center for Computing Activities (CUCCA), which was since renamed to Columbia
University Academic Information Systems (AcIS) and after that Columbia
University Information Technology (CUIT). Kermit is named after Kermit the
Frog, star of the television series THE MUPPET SHOW; the name is used by
permission of Henson Associates, Inc.
