Backported and Experimental Type Hints for Python 3.5+
Typing Extensions – Backported and Experimental Type Hints for Python
The typing module was added to the standard library in Python 3.5 on a provisional basis and will no longer be provisional in Python 3.7. However, this means users of Python 3.5 - 3.6 who are unable to upgrade will not be able to take advantage of new types added to the typing module, such as typing.Text or typing.Coroutine.
The typing_extensions module contains both backports of these changes as well as experimental types that will eventually be added to the typing module, such as Protocol.
Users of other Python versions should continue to install and use the typing module from PyPi instead of using this one unless specifically writing code that must be compatible with multiple Python versions or requires experimental types.

- update to 4.10.0:
This feature release adds support for PEP 728 (TypedDict with extra
items) and PEP 742 (``TypeIs``).
- Add support for PEP 728, supporting the `closed` keyword argument and the
special `__extra_items__` key for TypedDict. Patch by Zixuan James Li.
- Add support for PEP 742, adding `typing_extensions.TypeIs`. Patch
by Jelle Zijlstra.
- Drop runtime error when a read-only `TypedDict` item overrides a mutable
one. Type checkers should still flag this as an error. Patch by Jelle
Zijlstra.
- Speedup `issubclass()` checks against simple runtime-checkable protocols by
around 6% (backporting https://github.com/python/cpython/pull/112717, by Alex
Waygood).
- Fix a regression in the implementation of protocols where `typing.Protocol`
classes that were not marked as `@runtime_checkable` would be unnecessarily
introspected, potentially causing exceptions to be raised if the protocol had
problematic members. Patch by Alex Waygood, backporting
https://github.com/python/cpython/pull/113401.
- obsoletes backport-recent-implementation-of-protocol.patch
