* Mitigated the coveralls HTTP status 422 by pinning coveralls-python to <3.0.0 (issue #55).
* Fixed issues raised by new Pylint 2.9 and 2.10.
* Fixed a dependency error that caused importlib-metadata to be installed on
Python 3.8, while it is included in the Python base.
* Disabled new Pylint issue 'consider-using-f-string', since f-strings were
introduced only in Python 3.6.
* Fixed install error of wrapt 1.13.0 on Python 2.7 on Windows due to lack of
MS Visual C++ 9.0 on GitHub Actions, by pinning it to <1.13.
* Fixed potential issue with Sphinx/docutils versions on Python 2.7.
* Fixed error when installing virtualenv in install test on Python 2.7.
* Fixed that the added setup.py commands (test, leaktest, installtest) were
not displayed. They are now displayed at verbosity level 1 (using '-v').
* Support for Python 3.10: Added Python 3.10 in GitHub Actions tests, and in package metadata.
* Removed old tools that were needed for travis and Appveyor but no longer on
