If upstream really is making multiple releases called '6.4', which

There's only one official 6.4 release, but just about everyone packages
one of the roughly weekly snapshots inbetween releases (depending on
where you are looking they are also called beta versions), which are
named 6.4-yyyymmdd upstream. We can't have a "-" in the version number,
hence the suggestion to replace it with a "+".
[moving discussion to -apps]
Upstream developer is Thomas Dickey at invisible-island.net so no git.
My only concern is if 6.4+20240203-1 !> 6.4-20240120 as strvercmp test beds
disagree, presumably about the effect of the delimiter, possibly because the +
may be treated similarly to a prefix for an RC preceding the 6.4 release?
For guidance I have looked at:
https://docs.fedoraproject.org/en-US/packaging-guidelines/Versioning/
which states that ~ prefixes pre-stable "snapshot" releases and ^ prefixes
post-stable "snapshot" releases where . or nothing prefixes upstream bugfix or
patch level releases, so perhaps we should just use version suffix .yyyymmdd?
I have downloaded and locally installed Fedora rpmdevtools package but Cygwin
python rpm module seems to lack labelCompare():
$ rpmdev-vercmp 6.4+20240203-1 6.4-20240120
/usr/local/lib/python3.9/site-packages/rpm.py:15: UserWarning: The RPM Python
bindings are not currently available via PyPI.
Please install them with your distro package manager (typically called
'python2-rpm' or 'python3-rpm'), and ensure that any virtual environments
needing the API are configured to be able to see the system site packages
directory.

I also pip3 installed SAS SW rpm_vercmp which seems okay:

How are Cygwin pre-stable RC releases defined differently from post-stable
snapshot releases and upstream patch releases?
