✨ New & Improved

Area	What’s new
Type Checking	- Pyrefly now supports Annotated types and treats them as their base type for most purposes to better conform with the typing specification - Pyrefly now infers `Self` when constructing a class using `cls()`, also improving typing specification improvements - Pyrefly can now evaluate `os.name`, similar to existing `sys.platform` support, reducing false positives. - The `(*args: Any, **kwargs: Any)` syntax is now correctly treated as equivalent to the gradual signature `...`, aligning with Python's typing specification. - Improved handling when star-unpacking arguments to reduce false positives and improving typing specification conformance
Language Server	- Hover results for generic overloads now include type parameters. - New “Type source” section on hover that reports narrowing and first‑use inference origins
Documentation / Tooling	- pyrefly report now measures type completeness and annotation completeness for functions and their parameters.
Performance Improvements	- improved performance of concurrent rechecks, reducing latency for LSP requests like hover

📦 Upgrade

pip install --upgrade pyrefly==0.55.0

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.
