We’ve just uploaded mypy 1.13 to the Python Package Index (PyPI).
Mypy is a static type checker for Python. 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.
Note that unlike typical releases, Mypy 1.13 does not have any changes to type checking semantics
from 1.12.1.
Improved performance
Mypy 1.13 contains several performance improvements. Users can expect mypy to be 5-20% faster.
In environments with long search paths (such as environments using many editable installs), mypy
can be significantly faster, e.g. 2.2x faster in the use case targeted by these improvements.
Mypy 1.13 allows use of the orjson library for handling the cache instead of the stdlib json,
for improved performance. You can ensure the presence of orjson using the faster-cache extra:
python3 -m pip install -U mypy[faster-cache]
Mypy may depend on orjson by default in the future.
These improvements were contributed by Shantanu.
List of changes:
Significantly speed up file handling error paths (Shantanu, PR 17920)
Use fast path in modulefinder more often (Shantanu, PR 17950)
Let mypyc optimise os.path.join (Shantanu, PR 17949)
