It looks like the format for "glpsol --write ..." changed in Glpk
version 4.59, a version
described as a maintenance release.

I realise that this was probably deliberate.  Nevertheless, I would
like you to think of
it as a bug.

The effect of such a change is to break programs that interact with
glpsol.  In my case,
Gnumeric broke when some Linux distribution upgraded Glpk.

Please keep such interactions in mind for future format changes.

I note that neither the new format nor the old one contains any format
version indication.
Detection of format is thus inherently an ad hoc affair.
