How does versioning work?

[per-oestergaard]

After gotten a PR merged, I still cannot see the updated version after pip install pytm. This make we wonder how is versioning done and how packages are released? I get v1.2.1 from pip install. I find 1.2.0 in pyproject.toml and 1.2.0 in setup.py. I can also see a tag called v1.2.0.

I realize that I did not add anything to CHANGELOG.md as part of my changes.

Not every PR generates a release. We try to bundle some stuff before putting it out there. I need to sync pytm and github - .1 was a release fixing a typo, and pushed to pytm because there is more traffic there than here.
CHANGELOG.md changes manually as well.
