Rythal moved most of the updates to DEV already after he created the PTR. If I am correst he left the parts that broke the live current 6.1.2 on PTR and will move that when the 6.2 goes live.
I could be wrong though but most the errors and the version has been updated for the release of 6.2 on dev but certain code as per my bug report in Git.
