Oops, this seems to be not just a docs patch. I hope this still ok for backport.

defer removal of bundled libmpdec to 3.16

What is the rationale for defering the removal?

You can see the issue thread.

For my humble opinion the only excuse is that we miss removal of the implicit fallback to bundled copy (now#134078) in 3.14. (Though, this wasn't announced somewhere else.) We also miss libmpdec in latest ubuntu images. (I think this will be solved before 3.14 release.)

I still think we can stick to the original plan (that is: remove the vendored copy in 3.15). The only issue to solve is installing development sources on Ubuntu for 24.04.

FYI, I restored removal PR:#133964. I think libmpdec can be installed from PPA for PHP.

This, probably, requires approval from the release manager. Though,@hugovk removed request for review.

Deferring a breaking change is always a good thing :-)

An RM decision isn't needed for normal feature changes inmain aka 3.15. (And if it's deferred to 3.16, it's even less of this RM's decision :)

This affects 3.14 as well, as we change announced plans.

Since#134078 was just merged in Python 3.15, I think that it would be safe to postpone the removal to Python 3.16. Have one release with#134078 to see how it goes.

@skirpichev: There are now merge conflicts, can you try to address them?

Oops, now it doesn't make less sense to backport this (configure.ac changes will be manual). It's expected to be merged first, not after#134078.

Merged.

Do you mean that it doesn't make sense to backport this change, or that it should be backported manually?

No, it does!

that it should be backported manually?

Yes. I'll do this.
