There may well have /been/ versions 0.100 .. 0.903, but these
will all ne of only archival interest, since there is now
a version 0.982

Why, Frank ? Where is it written on tablets of stone (or elsewhere)
that versions must be differentiable by the first three significant
digits. Why can Staszek et al not propose LM-fonts V0.9821, being a
subtle improvement on V0.982, then V0.99, 0.991, 0.9911, 0.9912,
0.99121, and so on ? If Knuth may elect to number TeX as
and MF likewise (for e, rather than for pi) then why may others
not follow his lead of using real numbers to differentiate versions ?

"must" ? I honestly fail to see any logic in this last statement at
all. /Why/ "must" libconvert-binhex-perl version 1.119 be higher than 1.12 ?
It would certainly not appear to be so, if by "higher" you imply "more recent".

Yes, I agree : unless one knows how packages are numbered, one has
no way of differentiating between earlier and later versions based
solely on their name. But we /do/ know about the numbering scheme
for LM Modern, and therefore there is no problem. There /does/
seem to be a problem for "libconvert-binhex-perl", if version 1.119
is really "higher" (more recent) than 1.12, but that would appear
to be a problem for the author(s)/creator(s)/maintainer(s) of
"libconvert-binhex-perl" rather than for Staszek et al.

Not sure what this statement means ...

and if the Holy Father were a Protestant, then the entire Vatican
staff would be out of a job! But he isn't, any more than
0.100 is higher than 0.99, so what are we to gain by discussing
