I've added milestone link so that it's easier to compile release notes :)

Woah, what a great timing.

I am currently looking for a repository management tool for https://auto.debian.net/ (which is also written in Go btw).

I'd love to see this merged. If I understand, this is what I need to create repositories and add packages via the rest API?

From what I can see the API cannot currently do that. I'd love to be one of the first users and provide feedback, if you are interested.

@aviau Aptly already has support to create local repositories through API (https://www.aptly.info/doc/api/repos/). This PR is simply expanding the API to support .changes files as well.
