How to apply a license

Originally Nextcloud was licensed under the GNU AGPLv3 only. From June, 16 2016 on we switched to "GNU AGPLv3 or any later version" for better long-term maintainability and to make it more secure from a legal point of view.

Additionally Nextcloud doesn't require a CLA (Contributor License Agreement). The copyright belongs to all the individual contributors.
