I read at http://creativecommons.org/weblog/entry/7876 about the agreement to modify the FDL to make it compatible with CC-BY-SA, so that Wikipedia articles can be republished under CC-BY-SA. However, I was confused about two things:

1. I thought that the GFDL was already compatible with CC-BY-SA 3.0,

since they both required derivative works to be published under the same license. Is there a specific part where they're incompatible, or is it just a case that there are ambiguities about compatibility, and the FDL will be revised to remove all doubt?

2. More confusingly, I don't see how you can just "update" a license

and retroactively apply it to all existing content that had been published under an existing license. All the contributors to Wikipedia, for example, agreed to the terms of the old FDL when they submitted their work. How can the updated FDL be said to apply to that work if the authors didn't agree to it?

Doesn't the licence text say "GFDL 1.2 or later" ?
