What do you mean by "after they have happened"? The changes to an updated library don't affect you until you have upgraded to that version. The whole point of semantic versioning is to allow you or package managers you use to limit which libraries to update. So, semver is to let you know of braking changes exactly before they would happen, because until you actually upgrade the library, the change hasn't happened. Surely this makes sense? Maybe we are talking past each other.
