"Wikipedia Moves to CC 4.0 Licenses&quot

This change was made through a revision to the project’s Terms of Use, where all new edits to Wikipedia will be under version 4.0 of the CC BY-SA license. Older edits will remain under BY-SA 3.0, which allows adaptations to be made with 4.0-licensed material. This presents a small amount of complexity for reusers, but over time, as more and more of the project is revised, this will become less of a practical concern.

Version 4.0 of the CC licenses, first published in 2013, introduced several important updates and improvements. Some of the key benefits of this upgrade include greater internationalization, more practical attribution requirements, a grace period for correcting reuse errors, improved clarity and simplicity, and better handling of rights outside copyright, such as database rights. These changes make it an ideal fit for Wikimedia’s mission of simple, globally accessible reuse in a wide variety of contexts.
