astral-sh/ty (ty)

v0.0.39

Compare Source

Released on 2026-05-22.

This release removes the Python 3.9 branches from our vendored standard library stubs. ty now only has "full" support for
Python 3.10 and later, but will still report version-specific syntax errors and other diagnostics when --python-version 3.9
is provided via the CLI.

Bug fixes

• Avoid panicking on __new__ assignments to classes (#​25282)
• Preserve declaration order when synthesizing class fields (#​25249)
• Respect dict-compatible fallbacks in TypedDict unions (#​25242)
• Retain recursively-defined state in binary expressions (#​25277)

LSP server

• Add Quick Fix to remove redundant cast (#​25211)
• Classify property declaration semantic tokens (#​25322)
• Escape HTML syntax in docstring rendering (#​25247)
• Prefer symbols from standard library over those of the same name from third party libraries for import completions. (#​25108)
• Support type aliases in document symbols (#​25302)

Diagnostics

• Add error context for extra callable parameters (#​25269)

Performance

• Avoid exponential blow-up in fall-through narrowing (#​25278)
• Speed up include filtering for projects with many literal include patterns (#​25266)

Core type checking

• Allow enum member accesses on self (#​25077)
• Emit a diagnostic for subclassing with order=True (#​21704)
• Full-scope bidirectional inference for unconstrained container literals (#​25279)
• Infer dict(TypedDict) as dict[str, object] (#​24852)
• Refine Callable class-decorator fallback for unknown results (#​25250)
• Reject incompatible explicit variance in generic base classes (#​25327)
• Support multi-inference through type aliases (#​25245)
• Sync vendored typeshed stubs (#​25271, #​25172)
