Not really, this is a common misconception: redistributing code under
later versions of the GPL is explicitly allowed by the current licensing
terms (GPLv2 or later).

If it weren't the case, then we'd have to ask for permissions to all
copyright holders, which includes present and past contributors of
legally relevant portions of the code. What constitutes a "legally
relevant" portion is a matter of infinite arguments between copyright
