Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

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

Please remove the NEWS entry, it's not needed here.

@Eclips4 done, thank you

Having looked at the two links, I'm not sure that they add anything valuable beyond historic interest from 20 years ago -- I've opened #123846 as a sketch of a different approach to remove the links. I tried to add them as review suggestions but GH's interface made it too confusing, sorry.

I add DO-NOT-MERGE because I am perhaps 90% sure that Turner's alternative PR should be merged instead. But I am not quite sure enough to just do it.

@AA-Turner @terryjreedy Tbh I agree removing the links is better, I would even propose that links be removed from comments in general.

Closing in favor of #123846
