PEP 700 conformance for PyPI feeds
-
Hi @0xFFFFFFFF,
Thanks for the detailed write-up and explanation.
It looks trivial to add
sizeandupload-time. Addingversionsis probably simple, assuming it's just an array of distinct version numbers (we already have all the "packages" in context).It's probably fine, but just to be safe we will do this in ProGet 2026, given some of the subtle behavioral changes you mentioned ("tools like uv to make use of heuristics to speed up downloads"). For someone with an overloaded server, that might "put it over the edge".
ProGet 2026 may be ready by the end of the month, so it's not so far away.

Hi Dean,
Thank you very much for the reply!
This landing in ProGet 2026 would be awesome! But of course I understand you want to be certain that those changes would not cause issues for the users, so I think having to wait a little more would be no problem for me.

Hi @dean-houston,
Can I confirm that this was fixed in the ProGet 2026 26.0.0 release last week?
PG-3272
Major Release ProGet 2026 We are experiencing issues with UV attempting to resolve packages that are too new when configured with the "exclude-newer" property, presumably because it's looking for the
upload-timeand notpublishedin the response.For info, we are currently seeing non-PEP 700 compliance on version 2025.27
Thanks,

Hi @Ashley ,
It should have been; I just double-checked and see a commit for "Add full PEP 700 conformance for PyPI feeds" that appears to add the fields discussed here and some more.
Thanks,

Hi @stevedennis
I upgraded our dev server to 2026.1 and we are still having issues with the upload-time property. It appears that ProGet will only add the upload-time property when the package has been pulled to ProGet, i.e. not present for remotes.

Hi Alana,
Thanks for investigating! Is the maintenance release this Friday or the week after?
-
Hi @Ashley ,
We're planning this Friday... though it may not make it. Hopefully!
It's a bit more involved, since it involves calling the separate API instead of the simple API.
Cheers,
Alana -
Hi @Ashley,
It turns out that we just weren't reading
upload-timefrom the upstream json when using the simple API, so this was pretty trivial to fix and we'll certainly be able to include it in tomorrow's release.

Hi,
We just upgraded to 2026.2 and it looks good, thanks for getting the update out so quick!
