Release Notes

nedbat/coveragepy (coverage)

v7.8.0

Compare Source

• Added a new source_dirs setting for symmetry with the existing
  source_pkgs setting. It's preferable to the existing source setting,
  because you'll get a clear error when directories don't exist. Fixes issue 1942. Thanks, Jeremy Fleischman <pull 1943_>.

• Fix: the PYTHONSAFEPATH environment variable new in Python 3.11 is properly
  supported, closing issue 1696. Thanks, Philipp A. <pull 1700_>. This
  works properly except for a detail when using the coverage command on
  Windows. There you can use python -m coverage instead if you need exact
  emulation.
