Hey @lorthirk, just a heads up: I have noticed that the headers are not updated to current year (2020). Because this is a stall PR i suggest to update the header year right before the merge, to avoid changing them multiple times in case the PR is prolonged into 2021.

This PR is going to be merged in a few days, if not hours. I will try to update all the headers for the modified files if I find a quick way to do that.
