Please bump this package in portage to the latest upstream, which is 0.2.9.
This build also builds with Python-3.7, so we should consider adding python3_7 to the PYTHON_COMPAT in the ebuild.
Fedora is already shipping a python3.7 build of this package.
I have tested this bump and python flag and it builds and appears to run without any obvious issues.
Added 0.3.0, made tests pass, added py3.7 and py3.8.
