If you put the changed xml in 1.4.2, you *did* merge a database relevant
change into a minor version (exactly what you wanted to avoid).
Thats why I am nevertheless opting for a complete different branch designed to
take only patches/patched modules requiring a database update. It is a much
cleaner policy than to have a patch module in a release branch.
