The FSF has released version 1.3 of their Free Documentation License. The biggest change is that it is now compatible with Creative Commons Attribution-Share Alike 3.0.
This new permission has been added at the request of the Wikimedia Foundation, which oversees the Wikipedia project. The same terms are available to any public wiki that uses materials available under the new license. The Wikimedia Foundation will now initiate a process of community discussion and voting to determine whether or not to use CC-BY-SA 3.0 as the license for Wikipedia
…
Version 1.3 of the GNU FDL also adopts the license proxy and termination clauses that are part of the GNU General Public License version 3, released last year. The full text of the new license, along with more information, is available at http://www.gnu.org/licenses/fdl-1.3.html. The text of CC-BY-SA 3.0 is available at http://creativecommons.org/licenses/by-sa/3.0/.
The FSF is still accepting comments as it considers a major revision of the license, FDL version 2.0. More information is available at http://gplv3.fsf.org/.
I discussed the compatibility of the FDL with CC BY-SA in March. He didn’t seem happy about the idea of making them compatible, but I’m not sure why (something about taking away people’s freedom).
