Hi Stefan,

Normally, I'd say this needs to first add the new name, then remove the old one one release later. But since we're at the release boundary, we can announce on the 4.0 release notes that the name will change in the 5.0 release.

This means the patch cannot be backported to 4.0.

A few inline comments...

cheers,

Hi Renato,

This makes perfect sense to me.

Also, I will add the changes you suggested and resubmit shortly.

Such a note for 4.0 is completely inactionable though - the user can't change their build script because it's still called vulcan. I'm not sure how useful that would be.
