in issue#130160 we're making backports for3.12 and3.13 versions. since this is a similar PR I suggest to stick to the same strategy

I'll wait for Hugo's review and then we can probably merge it (just for a last checkup)

Do we need a NEWS file? This started out as docs only, but we're changing the code inpickle.py here. Although it's in code that was not documented before now, so maybe not needed?

We changed the code but it was already not documented. I don't think it's worth a What's New entry, but a small NEWS entry may be nice. We could make it under Library to mention that we now usepprint.pp instead ofpprint.pprint to render pickle files.

Please don't replace pprint.pprint() with pprint.pp() in this PR but write a separated change for that.

Ok, I reverted usingpprint instead ofpp

Thanks, remember to push :)

Merged, thank you.
