IANAL
Copyright is irrelevant, licence status is what's interesting (and that haven't changed during the years).
Most people don't understand that software licenses are extentions of the copyright which makes the copyright holder automaticly grant/revoke f.ex. distribution rights.
Also, licenses DO NOT APPLY to copyright holder. There's nothing wrong with distributing the same software with different packages under multiple licenses. Some people think that Gnu GPL includes copyright holder (read: author), but that's not true.
