Mypy Release Notes

Next Release

Mypy 2.0

We’ve just uploaded mypy 2.0.0 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. There are also changes to options and defaults. You can install it as follows:

python3 -m pip install -U mypy

You can read the full documentation for this release on Read the Docs.

Enable --local-partial-types by Default

This flag affects the inference of types based on assignments in other scopes. For now, explicitly disabling this continues to be supported, but this support will be removed in the future as the legacy behaviour is hard to support with other current and future features in mypy, like the daemon or the new implementation of flexible redefinitions.

Contributed by Ivan Levkivskyi, Jukka Lehtosalo, Shantanu in PR 21163.

Enable --strict-bytes by Default

Per PEP 688, mypy no longer treats bytearray and memoryview values as assignable to the bytes type.

Contributed by Shantanu in PR 18371.

New Behavior for --allow-redefinition

The --allow-redefinition flag now behaves like --allow-redefinition-new in mypy 1.20 and earlier. The new behavior is generally more flexible. For example, you can have different types for a variable in different blocks:

# mypy: allow-redefinition
def foo(cond: bool) -> None:
if cond:
for x in ["a", "b"]:
# Type of "x" is "str" here
...
else:
for x in [1, 2]:
# Type of "x" is "int" here
...

... (truncated)
