- Update to version 22.11.0:
* Bugfixes:
Specify encoding when opening files. Prevents UnicodeDecodeError on Windows when the file contains non-CP1252 characters. Contributed by Avasam.
Significant changes have been made to the Y041 check. Previously, Y041 flagged "redundant numeric unions"
(e.g. float | int, complex | float or complex | int) in all contexts outside of type aliases. This was incorrect.
PEP 484 only specifies that type checkers should treat int as an implicit subtype of float in the specific context of parameter annotations
for functions and methods. Y041 has therefore been revised to only emit errors on "redundant numeric unions" in the context of parameter annotations.
* Other changes:
Support running with flake8 v6.
