Release Notes

pytest-dev/pytest-rerunfailures (pytest-rerunfailures)

v16.3

Compare Source

Features
++++++++

• Add --reruns-mode option (strict or append). With append,
  marker reruns and the global --reruns / reruns ini setting are summed
  instead of the marker taking strict priority. Default is strict so
  existing behaviour is unchanged.
  Fixes #&#8203;321 <https://github.com/pytest-dev/pytest-rerunfailures/issues/321>_.

• Add --rerun-show-tracebacks option to display tracebacks from failed
  attempts that were retried, including tests that eventually passed. The
  rerun summary section is emitted automatically when the flag is set, so
  -rR is no longer required to see the tracebacks.
  Fixes #&#8203;156 <https://github.com/pytest-dev/pytest-rerunfailures/issues/156>_.

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)
