Royal Society lets Open Choice authors use CC licenses

The Royal Society has updated the copyright policy for EXiS Open Choice, its hybrid OA journal program.  Yesterday or today it posted the following language to the Open Choice page:

Authors participating in EXiS Open Choice will be able to disseminate their articles under the Creative Commons licence version 2.5 [Attribution - NonCommercial] allowing them to post the final published version on repositories as soon as the article is published. Authors should also deposit the URL of their published article, in addition to the full text.

Previously, the same page said only this:

Authors participating in EXiS Open Choice will be able to post the final published version on repositories as soon as the article is published.

Comment.  I applaud the RS for this step, which I recommended for all hybrid OA journal programs back in September.  I believe that Springer, Taylor & Francis, and RS are now the only hybrid OA publishers that let participating authors use CC licenses.
