This release addresses GHSA-vxvm-j4xq-q7m4, a use-after-free vulnerability during incremental type checking that can result in arbitrary code execution when analyzing a specially crafted Python project. Users who run ty on untrusted code should upgrade to 0.0.84 or newer. Bug fixes • Fix stale diagnostics from the LSP server after toggling

showSyntaxErrors

(#​28759) LSP server • Complete string keys from dictionary initializers (#​28820) • Support LSP requests against closed documents (#​28595) • Select projects for external files using import search paths (#​28594) • Use workspace editor settings for external files (#​28639) Performance • Avoid repeated subtyping checks for materialized recursive protocols (#​28774) • Skip reading notebooks when discovering scripts (#​28781) Core type checking • Avoid incorrect simplification of

TypeIs

materializations (#​28817) • Fix disjointness of generic class types (#​28787) • Fix staticmethod shadowing through generic receivers and unions (#​28766) • Infer callable signatures from bounded type variables (#​28599) • Infer constant membership in inline list and set literals (e.g.

"foo" in ["foo"]

is now inferred as

Literal[True]

) (#​28676) • Infer through optional generic containers in the legacy solver (#​28791) • Preserve call narrowing during cyclic inference (#​28708) • Preserve intersections of type guard return types (#​28796) • Use subtyping for constraint-set implication (#​28657) Configuration • Disable

invalid-legacy-positional-parameter

by default (#​28834) Other changes • Only consider reachable definitions when determining whether a condition should be exempted from

redundant-condition(-strict)

due to the condition being defined relative to

sys.version_info
