I like the date-based version. But you can also use a combination of both. But a semantic version number in front, and the date behind. I use that for a couple of projects, e.g.: https://pypi.org/project/better_exchook/ https://pypi.org/project/better_exchook/ Current version: 1.20200318.213331. The date/time is taken from the latest Git commit. Via this code: https://github.com/albertz/py_better_exchook/blob/2c106820ea334027ce585daa78cdfda753b918cc/setup.py#L96 https://github.com/albertz/py_better_exchook/blob/2c106820ea... If I need to break the API, or want to change the versioning scheme, I can just increase the major version number. For logging purpose, I also append the Git hash, and maybe "dirty", like this: https://github.com/rwth-i6/returnn/blob/7fa1f3e0595247c035b2641de9952f9227669475/Util.py#L292 https://github.com/rwth-i6/returnn/blob/7fa1f3e0595247c035b2...
