Dear Orthanc community,

I am honored to announce that in the continuous efforts of UCLouvain to reinforce the Orthanc ecosystem as a Digital Public Good for medical imaging, **no contributor license agreement (CLA) will be required** to submit source code to the project anymore.

This also means that dual licensing is no longer available and never will be again on any version of Orthanc that ships code owned by UCLouvain.

Check out the Orthanc Book for [more information about licensing](https://orthanc.uclouvain.be/book/faq/licensing.html).

Kind Regards,  
Sébastien-
