A lot of bug fixes are present in this release, focusing on Windows, PyPy, and cross compiling. We've also improved the compatibility with default setuptools behaviors a little, and enabled some things that were previously unavailable, like overriding the build type via the cmake argument environment variables. We've expanded our CI matrix to include Windows and macOS PyPy and some Fortran tests on Linux. This release requires Python 3.7+.
