v0.0.93

Released on 2026-10-28.

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.

Bug fixes

• Fix a panic when checking truthiness in a loop (#​29759)
• Fix hang when negating recursive unions of instance types (#​29652)

Core type checking

• Avoid synthesizing primary keys for abstract Django models (#​29744)
• 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)

Performance
