ดาวน์โหลด ty 0.0.30

As of v0.0.30, ty no longer unions Unknown into most inferred types of unannotated attributes. For example:
class Foo:
def __init__(self) -> None:
self.value = 1
reveal_type(Foo().value) # revealed: int
Foo().value = "x" # error: [invalid-assignment]
In previous versions, reveal_type(Foo().value) would have included Unknown, so the assignment to "x" would not have been flagged. Since this can affect inferred attribute types throughout a codebase, upgrading may lead to both new and resolved diagnostics. Initializers of None and other non-literal singleton types remain exceptions. See #24531 for details.

Bug fixes

LSP server
- Adjust semantic tokens implementation to ensure that type alias values have "type form" syntax highlighting in IDEs (#24478)
- Completions: rank symbols from typing and collections higher than third party re-exports (#23643)
- Ignore unsupported editor-selected Python versions (#24498)

- Show info subdiagnostics in LSP diagnostic messages (#24328)
- Use the context of the kind of object a parameter is expected to receive to inform syntax highlighting of arguments passed to call expressions (#23949)

Diagnostics
- Hide "Rule xyz is enabled"-style hints unless verbose mode was specified (#24469)
- Improve consistency of pedantic lints complaining about badly named types (#24575)

Core type checking
- Add support for functional Enum(...) syntax (#23602, #24570, #24571)

- Fix TypeGuard and TypeIs narrowing for unbound method calls (#24612)
- Fix assignability of intersections with bounded TypeVars (#24502)
- Fix excess subscript argument inference for non-generic types so that list[int][0] leads to 1 diagnostic, rather than 2 (#24354)
- Inherit dataclass_transform metadata from metaclass bases (#24615)
- Lazily evaluate declaration reachability in field and enum filters (#24451)
- Normalize explicit None accessors in manual property construction (#24492)
