Is there anything that needs to be done aside from just pressing the merge button?

@ericywl we usually use Squash and merge (avoid creating a merge commit). Please ensure a good commit message, ideally including some term to close the related github card. If there is a reason for keeping several commits in the history, then you can use Rebase and merge.
Other than that - just hit the button :)

As apm-data is a library, to incorporate this change into the projects (e.g. apm-server), we'll need to cut a release (in this case, a patch release) and bump the apm-data depenedency version (which is usually done by automation) in the projects. I'm not sure if we have docs on this process. We can sync up if you want to give it a go.

We should not close the apm-server issue until all of the above is carried out.

Hey Carson, sure I will give it a try.
