I think our changelog and readme should both state that we will attempt to track with https://github.com/nodejs/release#release-schedule and on a rolling basis we will not support Node.js versions that have fallen off that list.

In the changelog, let's put dependency upgrades after all other changes so that the document is easier to scan. Dependencies should appear in alphabetical order for readability reasons.

Please simplify https://github.com/mapbox/node-pre-gyp/blob/master/README.md#appveyor-automation to point readers to:

1. https://ci.appveyor.com/project/Mapbox/node-pre-gyp/history
2. https://github.com/mapbox/node-pre-gyp/blob/master/appveyor.yml
3. http://www.appveyor.com/docs/appveyor-yml

Please remove https://github.com/mapbox/node-pre-gyp/blob/master/README.md#travis-automation and instead briefly describe how to find our GitHub Actions and their test results.

Thanks much!!

I will leave the readme updates for someone who is more familiar with the details as I don't feel I would do a good job updating these sections.
