python3 -m pip install -U mypy

Type-checking Improvements
Do not intersect types in isinstance checks if at least one is final (Christoph Tyralla, PR 16330)
Detect that @final class without __bool__ cannot have falsey instances (Ilya Priven, PR 16566)
Do not allow TypedDict classes with extra keywords (Nikita Sobolev, PR 16438)
Do not allow class-level keywords for NamedTuple (Nikita Sobolev, PR 16526)
Make imprecise constraints handling more robust (Ivan Levkivskyi, PR 16502)
Fix strict-optional in extending generic TypedDict (Ivan Levkivskyi, PR 16398)
Allow type ignores of PEP 695 constructs (Shantanu, PR 16608)
Enable type_check_only support for TypedDict and NamedTuple (Nikita Sobolev, PR 16469)
Performance Improvements
Add fast path to analyzing special form assignments (Jukka Lehtosalo, PR 16561)
Improvements to Error Reporting
Don't show documentation links for plugin error codes (Ivan Levkivskyi, PR 16383)
Improve error messages for super checks and add more tests (Nikita Sobolev, PR 16393)
