4.3.0-pre

This is a PRE RELEASE. It is not marked as stable for a reason. Running this in a prod environment where stability is needed is not advised. Many, many things have changed. Cores are not inter-changable between versions

Many subsystems were completely redone in this release. Things may break. Please report them so I can yell at other maintainers
