Sub-interpreters may now be created with a unique GIL per interpreter. This allows Python programs to take full advantage of multiple CPU cores .

PEP 692: Using TypedDict for more precise **kwargs typing

• https://peps.python.org/pep-0692/

• https://docs.python.org/3.12/whatsnew/3.12.html#pep-692-using-typeddict-for-more-precise-kwargs-typing

PEP 692: Using TypedDict for more precise **kwargs typing

Typing **kwargs in a function signature as introduced by PEP 484 allowed for valid annotations only in cases where all of the **kwargs were of the same type.

This PEP specifies a more precise way of typing **kwargs by relying on typed dictionaries

from typing import TypedDict, Unpack

class Movie(TypedDict):
  name: str
  year: int

def foo(**kwargs: Unpack[Movie]):
    pass

See PEP 692 for more details .
