@elBoberido Your last commit message is not signed. Otherwise it looks fine.

@FerdinandSpitzschnueffler I tell you a dirty little secret. I NEVER sign my commits. It isn't required by eclipse anymore and therefore I skip this. Maybe we should also remove this from our PR template.

I wasn't aware of this. Then we definitely should remove this item from our template.

@FerdinandSpitzschnueffler I'll do that in my next PR
