✨ New & Improved

Area	What’s new
Type Checking	- For dict literals without a contextual hint Pyrefly will now infer an anonymous typed dict. This reduces false positives when unpacking a heterogeneous dict as kwargs. - Better suggestions hints for name and attribute errors (e.g. suggesting fixes to one letter errors like my_variuble → my_variable). - Callable types are now narrowed more intuitively, especially in isinstance checks. Callable Enums are also now supported - New check added (defaults to warn) for comparisons where the result is predictable or the comparison inappropriate (e.g. True is False). Reflects basic support for Pyright’s reportUnnecessaryComparison and Mypy’s comparison-overlap check.
Language Server	Automatic file renaming improved to allow editable third party packages to be renamed
Third Party Package Support	- Support for Pydantic lax mode has been extended to include support for container types (lists, dicts etc.) - All Django fields now support nullability, fixing issues with TextField and others - Pyrefly will now correctly infer the signature for functions decorated with numba.jit and numba.njit

📦 Upgrade

pip install --upgrade pyrefly==0.45.0

How to safely upgrade your codebase

Upgrading the version of Pyrefly you're using or a third-party library you depend on can reveal new type errors in your code. Fixing them all at once is often unrealistic. We've written scripts to help you temporarily silence them. After upgrading, follow these steps:

1. pyrefly check --suppress-errors
2. run your code formatter of choice
3. pyrefly check --remove-unused-ignores
4. Repeat until you achieve a clean formatting run and a clean type check.

This will add `pyrefly: ignore` comments to your code, enabling you to silence errors and return to fix them later. This can make the process of upgrading a large codebase much more manageable.
