on GitHub

Beartype 0.5.1 released.

This stable release significantly improves our front-facing README.rst as well as resolving an unrelated suite of minor issues.

Specific changes include:

Documentation Improved

• Overview commentary. The new top-level Overview section better outlines beartype's various tradeoffs, advantages, and disadvantages versus competing type checkers.
• Decorator commentary. The new top-level Decorator section documents code generated by @beartype under real-world use cases.
• Developer commentary. The new top-level Developer section assists other developers in contributing to @beartype.

Issues Resolved

• Deeply ignorable new types. @beartype now correctly ignores calls to typing.NewType passed ignorable type hints rather than merely object.
• PEP 544-compliant protocol detection. @beartype now reports all builtin types (e.g., int) to not be PEP 544-compliant protocols, despite a proper subset of builtin types erroneously claiming to be PEP 544-compliant protocols for strange and probably spurious reasons.

Tests Improved

• Python 3.9 exercised under CI. Our GitHub Actions-based continuous integration (CI) configuration now correctly exercises itself against Python 3.9 by explicitly passing the --skip-missing-interpreters=false CLI option to force CI failures when one or more Python environments are unavailable, resolving the upstream tox-dev/tox#903 issue for @beartype.
