From the Ch Ch ChangeLGPL.. dept.:
...the next draft of the LGPL will include a change.
Instead of being a separate license, the LGPL will be the GPL with additional privileges, a kind of template of what additions should be. First Stallman:
One of the nice things this has enabled us to do is: we have been able to rewrite the Lesser GPL - the GNU LGPL - so that it uses this clause. The GNU Lesser GPL will not have to restate most of the things in the GPL, it will say it's the GNU GPL plus these added permissions. One of the other benefits we get from this is that we make it clear that any time someone adds extra permissions on top of the GNU GPL, that when you modify the program you can take off those added permissions. You can release your version under the strict GPL and nothing more.
We've also made it clear that it's impossible, it's self-contradictory, to try to add any requirements that are not in our list of what's allowed. From time to time people do that. They say "This program is available under the GNU GPL except you can't use it commercially." This is a self contradiction. The result is nonsense. You can't tell, even, what that really means because it's not clear what the licence would be for modified versions.
With GPL version 3, it's going to be clear that any added restrictions that the GPL doesn't allow for can be removed.
