Note that 3.14 is in RC-mode, @hugovk may reasonably want to defer backporting this to 3.14.1 -- but by then, I expect a new version of pip will have been released.

Let's backport when ready: this will get wide exposure in 3.13.6 (2025-08-05) before 3.14.0 RC2 (2025-08-26).

Thanks!

I'm not sure how this could be out of date with main? Maybe the news files? Does anyone know a good reason why I shouldn't just hit "Update branch"?

@ichard26 ping me when you are ready for this to be merged, and I'll set the merge going and do the backports. For information, we bacport new versions of pip to all currently maintained Python versions. And as in this case, if we're in the beta or RC period, we should get RM approval. As @hugovk has approved, we're good on that point.

It's a somewhat-unhelpful message, this branch is indeed behind, but not for anything that matters (hence no 'resolve conflicts' message). Clicking the button doesn't hurt, but triggers a full CI rerun, so generally best avoided. It can be helpful when the problem is with CI itself, though.

It's been all quiet on the western post-release front so far (and I doubt we're going to discover any show-stopping bugs at this point) so let's get this merged now so it can be battle tested via Python 3.13.6. cc @pfmoore

Thanks @ichard26 for the PR, and @ZeroIntensity for merging it 🌮🎉.. I'm working now to backport this PR to: 3.13, 3.14.
