Hi Tim,

Do you think it would be feasible to keep the latest patch release available in PyPi for a certain period of time (maybe for 3-4 years)?

Or do you think that the python bindings will hardly be compatible with HTCondor daemons running in newer versions?

My understanding from the compatible release operator [1] is that, as long as there is a 24.0.x release in PyPi, we would be able to satisfy the htcondor version when building our application.

Best regards,

Alan.

Thank you for your responses.

We specify a single version, because we usually perform validation tests before moving to a different version. We are currently using 24.0.10.

I don't have a really good answer for you. Due to limited space on PyPI,
we have to remove older versions to make room for new versions.

However, our LTS version interface remains stable during the lifetime of
the series. The only thing that would have a stable version number for
the 24.0.x series, would be to have a 24.0 version and used -post1
-post2 suffixes.

Could you specify a range in your requirement? htcondor>=24.0.0,<=24.0.999
