The common rule has always been, that we're backward compatible, if you can 
replace the old jar with the new version. If this switch requires an upgrade 
of the environment, it's fine. The old version will (normally) run as well 
on the on the updated environment as the new one will. But the application 
itself has not to be modified or compiled.

Updating the major version is also always a signal to users for a migration 
effort. Chances are nowadays high, that we use a new package name ;-)
