I ran cargo semver-checks just to make sure there were not any breaking changes and it returned some small changes in the build crate:

Can you verify this before we merge?

Can you verify this before we merge?

Oops, I should have mentioned that. I noticed it also when I ran cargo semver-checks.

In one of the PRs this was discussed. I am of the opinion that it is OK, as these should have been private in the first place.

Do you agree this is acceptable? If not, I will create a PR to revert it.

@caspermeijn sounds good, just be aware that we may need to yank if someone runs into issues if they use it. But I agree that its likely not going to be an issue so we can move foward with this release.
