Hello Andy, I somehow missed your original mail about jbuilder 1.0~beta18. Is there already someone from the team looking at your updated package? Otherwise I can look at it over the weekend.
Concerning your question about a package rename : that depends on whether it is a rename of the source package or of a binary package. Renaming a source package is not possible, so you would have to upload a new source package and ask for removal of the old one. Renaming binary packages is easier : you just change the name in the debian/control file, and you add Breaks/Replaces between the old binary package and the new one. However, this counts as a new binary component, so it has to go through the NEW process. -Ralf.
