Preview features

  • Add diagnostic baselines to help adopt ty in projects with existing errors (#​27636). Configure a baseline in pyproject.toml:

    [tool.ty]
baseline = "ty-baseline.json"

    Run ty check --update-baseline to record existing diagnostics. Subsequent checks filter matching diagnostics from CLI output and show them as hints in the language server. The baseline format may change while the feature is in preview.

Core type checking

  • Combine constraints from repeated ParamSpecs (#​29172)
  • Fix narrowing of strings and integers compared with enum members (#​29743)
  • Honor @override on overload implementations in stubs (#​29470)
  • Preserve caller type variables in nested union inference (#​29611)
