The final version of the GPL Affero license, Version 3.0, has been released.
The Affero license is designed for network use, and is often used in Software as a Service systems where open source is used.
The Free Software Foundation, emphasized in a statement that the new license is not based on the previous Affero license, but on the GPL v. 3 released a few months ago. As the statement explains:
The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community. It requires the operator of a network server to provide the source code of the modified version running there to the users of that server. Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
In other words, you are supposed to have the same freedoms with SaaS as you do with client software. The GPV Affero V.3 license is designed to do this.
