Set up automatic changelog

[Almad]

The manual changelog is error prone and also contributes to procastinating on releases.

I have good experiences with semantic-release from JS world, so unless someone has better suggestions, I will set up something like https://github.com/relekang/python-semantic-release

As a recommendation, don't try to have a full changelog. Do 'upgrade notes' or something. Be meticulous about including any breaking changes, but that's mostly all you need.

The main thing I (and I suspect a lot of people) use changelogs for is to answer the question: is it safe to update to the new version? A changelog that literally only lists breaking changes is very easy to maintain.

Good point. I am maintaining full changelog given that's how it was done before in the project, but breaking changes are probably more readable for everyone :) (for everyone else, there is git log)
