@Anj-A
Are you sure this is the right BPO issue number? Looks like it should be under bpo-38652

Thanks for the PR @Anj-A, this looks exactly as I described in the issue, with removing the provisional note while retaining a versionadded note. I'll add a label to backport it to the 3.8 branch as well.

Also, if you could update the PR title to be more specifically descriptive of the changes made, that would be helpful. The actual changes made are correct though.

The only thing remaining after that is for the CLA to be signed and processed, but that usually only takes around 24-48 hours.

[Anj-A]

Have signed the CLA and updated the title as suggested.

I'm having trouble backporting to 3.8. Reason: 'Error 110 while writing to socket. Connection timed out.'. Please retry by removing and re-adding the needs backport to 3.8 label.

[asvetlov]

Thanks!

[asvetlov]

The fix should not be backported to 3.8, that's perfectly fine if 3.8 still states that BufferedProtocol is still provisional.
Changing something in 3.8.1 is worse than keeping the status quo until 3.9

Okay, I'll remove the backport label then.

Does this also apply to other provisional APIs as well, as in they remain provisional for the major version they were released on?

[asvetlov]

I doubt if we have a strong rule for the provisional status cleanup.
I only recall discussions for removal something in 3.X, and never for 3.X.Y.
