Changelog

6.5.0

--------------------------

- The JSON report now includes details of which branches were taken, and which
are missing for each file. Thanks, Christoph Blessing (`pull 1438`_). Closes
`issue 1425`_.

- Starting with coverage.py 6.2, ``class`` statements were marked as a branch.
This wasn't right, and has been reverted, fixing `issue 1449`_. Note this
will very slightly reduce your coverage total if you are measuring branch
coverage.

- Packaging is now compliant with `PEP 517`_, closing `issue 1395`_.

- A new debug option ``--debug=pathmap`` shows details of the remapping of
paths that happens during combine due to the ``[paths]`` setting.

- Fix an internal problem with caching of invalid Python parsing. Found by
OSS-Fuzz, fixing their `bug 50381`_.
