I've argued against, I've tantrumed, I've grumbled, I've hated the idea, I've recognized that it is going to piss users off immensely as they will never see the lost pain. That said - +1. Change the top level package name and groupId to math2. I'll be voting for Lang to be lang3. The only sane thing for us to do until OSGi is the standard is to put the major version number in the package name. This is not the same as 'math2 1.0'. That's just insane. So it's Math 2.0 - org.apache.commons.math2.
