Hmm. It comes down to compatibility again. This isn't immediately clear to me either way from reading the license; instead of trying to interpret, I'm going to punt the question. [EMAIL PROTECTED], a question (in a few forms): Is it valid to combine GPL work placed under "GPL version 2" with one under "GPL version 2 or any later version"? That is, do versioning choices impact compatibility (when the versions overlap)? Are all future modifications bound to give the same permission to upgrade the GPL? It seems like an added restriction; "version 2" implies "no upgrades allowed". It would allow a third party to prevent his modifications from being used in the original work, if the original authors want to maintain "or any later version", by not granting that permission in his modifications (which is exactly something GPL#6 seeks to prevent). If not, it's worse: GPL software, under a canonical interpretation, would be incompatible with other GPL software due to differently exercised license options. As many people do, in fact, omit "or any later version", it would probably be a real-world problem. -- Glenn Maynard
