v0.3.0

Python support

• Test against Python 3.14 pre-releases.
• Drop Python 3.8 support.
• Drop PyPy 3.9 support.

Added

• Add a database index to improve import performance.
• Support calls to importlib.metadata.version().
• Partially support accessing resources in packages.
• Support binary files (like non-UTF-8 Python modules) and resources.

Fixed

• Fix a bug in the bundling code that allowed non-Python files to be importable.

  Previously, a package containing a PEP 561 py.typed file
  would have an importable submodule named {package}.py.

• Fix a bug that prevented databases bundled on Windows from finding package metadata.

Changed

• Introduce a data access object to manage database interactions.
• Create a sqliteimport table to store metadata about the database.
• Bundle .dist-info/ metadata directories into databases.

Documentation

• Use an absolute URL to the banner in the README.

  This helps ensure that PyPI releases will render the README consistently.

Development

• Test that Unicode filenames can be imported.
• Add a script to generate a large Python package for performance testing.
• Resolve a ResourceWarning in the test suite on Python 3.13.
• Add CI testing.
• Create a framework for testing bundling and importing.
• Migrate to PEP 621 metadata in pyproject.toml.
• Create release PRs via a reusable workflow.
