Fixed:

  • Fix removing sources using an empty string value in the mapping
  • The strict-naming option now also applies to the metadata directory of wheel targets

1.5.0 - 2022-07-11

Added:

  • Support the final draft of PEP 639
  • Add strict-naming option for sdist and wheel targets

Fixed:

  • Project names are now stored in sdist and wheel target core metadata exactly as defined in pyproject.toml without normalization to allow control of how PyPI displays them

  • Don't sort project URL metadata so that the rendered order on PyPI can be controlled

1.4.0 - 2022-07-03

  • Improve performance by never entering directories that are guaranteed to be undesirable like __pycache__ rather than excluding individual files within
  • Update SPDX license information to version 3.17

Fixed:

  • Don't write empty entry points file for wheel targets if there are no entry points defined

  • Add uri and real context string formatting modifiers for file system paths
