mako writes "The Free Software Foundation has released the Affero General Public license version 3. The license is essentially the GPLv3 with an added clause that requires that source code be distributed to users that interact with the application over a network. The license effectively extends copyright to Web applications. The new AGPL will have important effects for companies that, under the GPL, have no obligation to distribute changes to users on the Web. This release adds the license to the stable of official FSF licenses and is compatible with the GPLv3."
