I noticed we have a changelog but it doesn't seem to be updated anymore. Should I add my changes to that, or have we decided to not use it? 🤔

I think this is an artifact of a time where we were experimenting with different ways to version deployed code and maintain release notes. On veda-backend we ended up doing this using Github releases, which is way easier than maintaining the changelog manually. It might be worth trying to crosswalk those actions into this repo to start maintaining something similar.
