If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

Hi I'm curious if this would be backported to 3.8 version? Thanks

Python 3.8 only gets security fixes, and 3.8 releases are now provided as source only, so I don't think this qualifies for backporting on either count.

• https://peps.python.org/pep-0569/#source-only-security-fix-releases
• https://devguide.python.org/developer-workflow/development-cycle/#security-branches

You can update pip through pip (e.g. python -m pip install --upgrade pip) or through your distro package manager.

I think what we've observed is that there's a vulnability in pip 23.2, and pip 23.3 would fix it, do you think this would qualify a bump for the security fix? https://nvd.nist.gov/vuln/detail/CVE-2023-5752

I'm also curious about the statement "Provided irregularly on an “as-needed” basis until October 2024." What are the regular security fixes that the community is watching an eye on for 3.8 to do the source fix?

I don't think so, but it's up to the release managers and security team to decide. My understanding is that the CVE would only affect people trying to install a package from a Mercurial repo. Plus I'm not sure how worthwhile it is updating a pip binary file in a source-only release, when pip can be directly updated in other ways.

But let's ask 3.8 release manager @ambv to confirm.

I'm also curious about the statement "Provided irregularly on an “as-needed” basis until October 2024." What are the regular security fixes that the community is watching an eye on for 3.8 to do the source fix?

It means there are no longer planned release dates for new 3.8 versions. If a security fix comes up that is important enough to warrant a 3.8 release, one will be made at that time.
