Summary
This release adds support for Python 3.10 which dropped the long deprecated `collections.MutableMapping`. Support for Python 2.7 continues.
Behind the scenes, the old travis-ci.org tests were dropped (as that service is no longer running), and a much more fleshed out test pipeline is now running on GitHub Actions.
