…the Wikimedia Foundation Board of Trustees passed a resolution that will bring about significant changes to the way the content of the Wikimedia Foundation projects, including Wikipedia, will be licensed. This resolution follows a vote among the international Wikimedia community. More than 17,000 votes were cast, with strongest participation in English, German, French, Russian, Spanish, Polish, Italian, and Chinese. 88% of all voters who expressed an opinion supported the change.
All Wikimedia content can be used for any purpose, as long as proper credit is given and modifications are made available under the same terms. This open access approach to copyright is supported using a license which explicitly grants everyone those freedoms. The decision will result in all of the Wikimedia Foundation’s projects moving from the GNU Free Documentation License (GFDL) to the Creative Commons Attribution/Share-Alike License (CC-BY-SA) as their primary content license. The GFDL, which has served Wikipedia since its inception, will continue to be supported where possible, but not to the detriment of interoperability.
