Sorry, but do you mean
a) commit this and pack the other three chaneges in a different commit
b) pack the first four changes in one single commit

[tcberner]

I meant b) :)

Pack the four first changes in one single commit

As of Committers Guide "Procedure 1. Steps for New Committers":

• Add an Author Entity
• Update the List of Developers and Contributors
• Add a News Item
• Add a PGP Key
