🔍Release Highlights

Type Checking

• New diagnostics and more accurate type inference. Pyrefly now catches invalid literal regular expressions, invalid mock.patch targets, unsupported dataclass_transform arguments, incompatible Protocol.__call__ overrides, and unimplemented abstract methods. Pattern-match exhaustiveness, overload resolution, narrowing, and generic inference are also more accurate.
• Better support for major Python frameworks. Pyrefly understands same-file Django reverse relationships, checks SQLAlchemy updates against model fields, and recognizes attributes registered on PyTorch modules.

Language Server

• Search the whole workspace for methods and nested definitions. Workspace symbol search now covers methods, nested classes and functions, and class attributes even in unopened files.
• New editor refactorings and quick fixes. Change Signature updates a function and its call sites together, while new quick fixes remove unused imports and insert assert x is not None. Inlay hints can also insert required imports and link to definitions.

Configuration & CLI

• Target individual Pyrefly errors with standard suppression comments. # type: ignore[pyrefly:<code>] suppresses a specific Pyrefly diagnostic without hiding unrelated errors on the same line.
• Choose how Pyrefly handles untyped dependencies. The new --replace-untyped-imports-with-any option replaces selected third-party packages that lack stubs or a py.typed marker with Any, and pyrefly init translates mypy's follow_untyped_imports setting automatically.
• Baseline files are easier to maintain and review. Baselines can match by concise description instead of source position, use a compact format, show existing errors at reduced severity, remove stale entries with --prune-baseline, and reject them in CI with --error-stale-baseline.

Experimental Extensions

• Much broader shape-aware JAX and NumPy support. New JAX stubs cover array creation, manipulation, and linear algebra, while the new pyrefly-numpy-stubs package brings shape checking to NumPy. These stubs use a new type-level shape DSL, which replaces the old @shaped_array API.
• Expanded Polars and pandas DataFrame schema support. Pyrefly tracks Polars schemas through common DataFrame transformations, with support for typed Series and schema annotations. pandas columns= projections now preserve the requested schema as well.

✨ New & Improved

Type Checking

• Pattern matching gained stronger exhaustiveness checking, including tuple subjects and open types such as unions. Open-type exhaustiveness now has its own configurable non-exhaustive-match-open-type error kind.
• Overload selection now follows the latest typing specification more closely, producing a safe common return type for gradual arguments and reducing false positives in complex overloads.
• Type inference and narrowing are more precise for membership tests, equality checks, hasattr, wide Literal unions, callable values, reverse tuple slices, and values assigned from Any.
• Dataclass fields backed by descriptors are now checked for incompatible read and write types under the new bad-dataclass-descriptor error kind.
• String targets passed to unittest.mock.patch are validated, with nonexistent attributes reported as missing-attribute-patch-target warnings.
• Literal regular expressions are checked for invalid patterns and capturing groups under the new regex error kind.
• Django support now understands reverse ForeignKey, OneToOneField, and ManyToManyField relationships in the same file, while Django REST Framework serializers avoid false override errors for common Meta and field patterns.
• SQLAlchemy update().values() checks values against mapped model fields.
• PyTorch modules recognize attributes registered through register_buffer and register_parameter.

Language Server

• Workspace symbol search now includes methods, nested classes, nested functions, and class attributes.
• Cross-file call hierarchy, type hierarchy, and find-references now work without first opening every relevant file.
