Create an easy way to view changes to the public API

Reviewing PRs is time consuming, so I'm open to any thing that makes reviewing PRs easier. One idea I had was having a automatically generated file that shows the entire API of the SDK. With this file it'd be very easy to spot if and how the public API has changed. This also has the added benefit of being usable within changelogs. I've tried this before and the way I approached this problem is by converting the generated documentation code into markdown and then filtered the markdown using `sed` and other programs.
