✨ New & Improved

Type Checking

• Attrs classes are now fully supported with comprehensive field synthesis, validation, and special-method generation. Pyrefly recognizes @attr.s, @define, @frozen, and their variants, handling field specifiers (attr.ib(), field()), converters, validators, defaults, and private-field aliasing. Converters are typed from their real input type rather than Any, including the @<field>.converter decorator, attrs.converters.pipe, attrs.converters.default_if_none, and generic converters like copy.deepcopy. See the new attrs documentation for details.
• functools.partial is now type-checked instead of treated as opaque. Bound arguments are validated at construction and Pyrefly synthesizes a precise residual signature for the remaining parameters, so errors surface at both the partial(...) call and the later invocation. Generic functions, overloads, constructors, bound methods, and **Unpack[TypedDict] parameters are supported, and results expose .func, .args, and .keywords. Precise residual callable assignment is enabled by the strict and all presets or explicitly with strict-partial-subtyping.
• Functions decorated with functools.singledispatch now type-check calls using the signature of the function you decorated, and registered implementations are checked against that function's first parameter. Generic singledispatch functions infer from call arguments instead of reporting Unknown.
• Pyrefly can now warn when a function declared to return a concrete type returns Any, with separate diagnostics for explicit and inferred cases. Off by default, and migrated automatically from mypy's warn_return_any.
• Pattern matching is substantially more precise: positional class patterns resolve attribute names from __match_args__ at solve time, sequence element captures read from the narrowed subject so sibling constraints refine them, and isinstance on a facet filters the parent union to matching members. Fully covered class and sequence patterns now subtract their union member from later cases.
• Unpacking a variadic tuple with a fixed prefix and suffix no longer smears those elements into the starred capture, so a, *rest, b = t where t: tuple[int, *tuple[bool, ...], str] types rest as list[bool].
• TypedDict classes now synthesize __required_keys__ and __optional_keys__, so protocols requiring them (like those in langgraph) satisfy structural checks. .get() and .pop() with literal defaults preserve the field type.
• Overload handling improved throughout: constrained TypeVar arguments expand during resolution, rejected overloads no longer leak argument errors into diagnostics, and exact callback-forwarding signatures resolve overloaded callbacks against forwarded arguments for helpers like asyncio.to_thread.
• Enum .value on an enum type now infers as the union of member literal values instead of widening to the mixed-in data type.
• Lambda parameters are contextually typed more thoroughly. Types are stored directly rather than resolved through inference variables, and *args/**kwargs resolve from callable hints to tuple[...] and dict[str, ...] inside the body while preserving element types in the signature.
• All properties are now treated as data descriptors, and reflected binary-operation dunders are tried first for proper subclasses, fixing a class of incorrect attribute and operator results.
• Cyclic type aliases reachable from an annotation are now detected instead of hanging, and class finality is taken into account when deciding whether a condition is redundant.
• Continued basedpyright parity work: class instance truthiness is recognized, code under if TYPE_CHECKING is handled consistently, typing_extensions.sentinel is supported with relaxed naming restrictions, and super(cls, cls) is accepted.
• copy.replace is now type-checked like dataclass replacement, and isinstance(x, type) preserves type arguments when narrowing unions.
• Narrowing a receiver typed as Self to a subclass now preserves Self, eliminating false return errors in methods that return the narrowed receiver.

Library Support

• Pydantic constructor synthesis now honors populate_by_name and built-in alias_generator functions, ignores Field(init=False) to match runtime, and treats frozen as a readonly field reason.
• Django ForeignKey targets now resolve attribute expressions and string references such as "app_label.Model", preserving the generated relation and <field>_id types.
• Bare factory-boy factory calls now return the model type via FactoryMetaClass.
• PEP 561 partial stub packages are now supported in imports. Pyrefly reads the partial marker from py.typed and merges the stubs with the runtime package, deferring to the runtime package for omitted modules while preserving .pyi-before-.py precedence for provided ones.
• A configured typeshed-path now supplies stdlib stubs as well as third-party stubs, enabling complete custom-typeshed testing and overrides.

Language Server

• Hover now resolves keyword arguments, renders callable protocols as their __call__ signature, preserves overload docstrings at call sites, shows enum fields, wraps nested callable and Concatenate[...] signatures for readability, and covers and/or operators, augmented assignments, and union methods.
• Auto-import completions respect python.analysis.autoImportCompletions, rank deprecated stdlib typing aliases below their modern equivalents, avoid duplicates for already-imported modules, and preserve import aliases correctly.
• Rename now works on aliased imports and across files for keyword arguments, and renaming a Protocol class targets the class rather than __init__.
• Go-to-definition now navigates directly to symbols in non-Python files such as .thrift, including nested attribute and enum access and intermediate components of multi-dotted imports.
• Inlay hints debounce server-side (default 150ms), preventing width jitter while typing. NewType values now use their callable constructor signature instead of producing an invalid type[N] annotation.
• Notebook support improved: hover and type lookups work past the first cell, and inlay hints, document symbols, references, and diagnostic grouping work in cells following markdown cells.
• Document symbols fall back to flat SymbolInformation for clients such as Helix, semantic tokens cover with ... as and except ... as bindings, and cross-file diagnostics refresh on save in strict-spec clients such as Zed.
• #region/#endregion markers create folding regions, and selection ranges now follow AST nesting from expression to statement to scope to document.
• Baselined errors now appear as hints instead of errors, making it easier to distinguish new issues from known technical debt. Baselining also now applies correctly to unused-ignore diagnostics.
• Match captures receive consistent semantic highlighting and preserve their declaration identity for go-to-definition.
• lspArguments defaults to ["lsp"] when empty, preventing startup failures in dev containers and remote environments.
• The VSCode extension adds an "Infer Types for Current File" command to the command palette.

Looks like these dependencies are updatable in another way, so this is no longer needed.
