This moves all the things we planned to remove in 3.15 but didn't to the appropriate pending removal in 3.16 file.

Additionally, move a misplaced entry from the 3.16 C-API removals file to the 3.16 main file removals.

  • Issue: interp-lifecycle.rst has incorrect deprecation ranges #150032

Sorry, something went wrong.

Thanks for updating this, and the 3.15->3.16 bumps should also be backported.

In recent release cycles, we've had feedback that it was too early to remove some things during pre/early alpha and added them back, so I'm a bit cautious about doing during beta.

But if someone wants to do so, please first check things like the top PyPI packages/GitHub/grep.app to get an idea if they're still too widely used, and maybe we can do it before b2.

I'm not sure that the drop of "set or" was intentional here? It seems that the language changed from the 3.15 pending.

I'm mainly curious because the __loader__ bullet directly above still uses "set or taken into consideration" language. To an end user the two phrasings probably don't really mean different things, either way the guidance is "stop relying on it", so the divergence between the two bullets reads as accidental.

Because we tried to remove ever reading __package__ and pip broke. So we don't set in anymore in 3.15, but we are not at a place where we can stop reading it if gets set. As for __loader__, it's a different stage of going away.
