Description

I think it is reasonable to say that for v5.3.x, we will not support NumPy 2.0 or later? The support for v5.3.x will end anyway when v6.0.x is cut, which is schedule to be by the end of 2023.

Motivations:

  • By checking this box, the PR author has requested that maintainers do NOT use the "Squash and Merge" button. Maintainers should respect this when possible; however, the final decision is at the discretion of the maintainer that merges the PR.

@pllim pllim added numpy-dev skip-basebranch-check Skip base branch check for direct backports labels Aug 27, 2023
@pllim pllim added this to the v5.3.3 milestone Aug 27, 2023

Thank you for your contribution to Astropy! 🌌 This checklist is meant to remind the package maintainers who will review this pull request of some common things to look for.

  • Do the proposed changes actually accomplish desired goals?
  • Do the proposed changes follow the Astropy coding guidelines?
  • Are tests added/updated as required? If so, do they follow the Astropy testing guidelines?
  • Are docs added/updated as required? If so, do they follow the Astropy documentation guidelines?
  • Is rebase and/or squash necessary? If so, please provide the author with appropriate instructions. Also see "When to rebase and squash commits".
  • Did the CI pass? If no, are the failures related? If you need to run daily and weekly cron jobs as part of the PR, please apply the "Extra CI" label. Codestyle issues can be fixed by the bot.
  • Is a change log needed? If yes, did the change log check pass? If no, add the "no-changelog-entry-needed" label. If this is a manual backport, use the "skip-changelog-checks" label unless special changelog handling is necessary.
  • Is this a big PR that makes a "What's new?" entry worthwhile and if so, is (1) a "what's new" entry included in this PR and (2) the "whatsnew-needed" label applied?
  • Is a milestone set? Milestone must be set but we cannot check for it on Actions; do not let the green checkmark fool you.
  • At the time of adding the milestone, if the milestone set requires a backport to release branch(es), apply the appropriate "backport-X.Y.x" label(s) before merge.

Hmm... Looks like this warning somehow went away again in dev scipy?

@pllim
TST: Update modeling test logic
9580b23 
that now fails in devdeps with scipy dev.
Since this is backport branch and the warning may or may not appear,
let's just blanket ignore the unsuccessful fit because test case
is not well defined to begin with.

@pllim - am happy to approve this, though perhaps good to have someone from the @astropy/astropy-project-release-team approve too? Though, in a way, this really just makes sense...

Is there a reason to have the minimum build version higher than the minimum runtime version? That’s generally the thing that has caused problems in the past and is the reason for oldest-supported-numpy.

Numpy 1.25 is the first version that supports backward compatible builds. The release notes explicitly mention that the mechanism makes oldest-supported-numpy not needed

What about v5.0.x? Should we make the same change there?

I already did that much earlier due to something else. So now both of them are pinned.
