Is adding a Bricklink reference enough to republish a part

[Manfred Schaefer]

That's not what I'm saying at all. What I am saying is that header changes for already official parts can be fast tracked. This is something that we already do.

The fast track system sounds good. 
This reduces or avoids the additional burden on the reviewer. Only the administrator needs to agree and approve. Do I understand this in the right manner?
Who is the administrator, is it Chris?
Since the parts have already been published, the only way to do this is by email.
In my email I have attached a comparison of the two Minig Heads from LDraw and Bricklink. This should be enough as a check, I hope.
Should this change be documented in a HISTORY line or not, as it is not a design change?

Greetings
