https://github.com/ponnhide/patchworklib#news

0.6.5 is the latest version on PyPI, but no source tarball was attached there or on GitHub under tagged Releases. Temporarily use the tarball of the corresponding commit until there is a tagged one.

The upgrade fixes a failed test tests/test_patchworklib.py::test_example_plot. Error found on the 3.21 builders (error log).

        old_legend = self.legend_
>       handles = old_legend.legendHandles
E       AttributeError: 'Legend' object has no attribute 'legendHandles'. Did you mean: 'legend_handles'?
