Python 3.8 has recently been released, however, presently, Gridsync cannot be used with Python 3.8 due to its current (sub)dependencies on certain newly-deprecated features -- including the platform.dist function, and (transitively, via txtorcon) importing Abstract Base Classes via collections (instead of collections.abc).

Gridsync's dependence on platform.dist can be resolved by switching to the distro package, while a new release of txtorcon will (presumably) include the recently-merged change to use collections.abc instead of collections (cc @meejah).

Other changes may need to be made on top of the above to consider Python 3.8 "supported" (such as adding python3.8 CI/test runners and testing for any regressions, e.g., with PyInstaller-generated binaries).
