1.4.2:
* Included a pyproject.toml to allow users install the sdist with old python/setuptools, as the setuptools-scm dep will be fetched by pip instead of setuptools.
1.4.1:
* Fixed wheels being built with ``-coverage`` cflags. No more issues about bogus ``cext.gcda`` files.
* Removed useless C file from wheels.
* Changed ``setup.py`` to use setuptools-scm.
1.4.0:
* Fixed ``__mod__`` for the slots backend.
* Dropped support for Python 2.6 and 3.3.
