Let's see if this survives a CI run...

Looks like the changes to the approval file is all just some sorting differences, which is to be expected.

Looking at the size of the file, it would still be a really good idea to go through the types in the project and change the accessibility of most them to internal, which would make the file be a true representation of the public API surface.

A lot of that has been done in master already, with more to be done post 6.0. I'm probably not going to do that for 5.x because I don't want to screw something up.

Sure, those kind of changes need to be done in a major. This PR is against master which is why I brought it up here.

@bording if you have time to "internalize" or "privatize" more parts of the public API prior to version 6.0, that would be great. I can't really get to that until I get 5.2.0 out the door.

@lukebakken I'll see what I can do. I am going out of town this week, so I might not have time until next week.
