Release Notes

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)
