Changelog for Heptapod
Currently the Docker image is the only assembled and released form of Heptapod, therefore it makes sense to put any global changelog right next to the Dockerfile, in heptapod/omnibus. That will make for easy inclusion in the README.
At the same time, everybody is used to file most issues (i.e., without prior knowledge that it's about a very specific component) against heptapod/heptapod. I just hope it won't be too weird to have global issues attached to one component and the changelog attached to another one.
Making changelog for each of our specific component looks like a waste of time at this point in the project.
