From 69feadc782affa4a9b6bfb718fd5ef6460ada613 Mon Sep 17 00:00:00 2001 From: Dan Handley Date: Tue, 18 Feb 2020 17:58:20 +0000 Subject: [PATCH] Drop requirement for a CLA The Mbed TLS project no longer requires a CLA. Contributions from now on must be made under both Apache-2.0 AND GPL-2.0-or-later licenses, to enable LTS (Long Term Support) branches of the software to continue to be provided under either Apache-2.0 OR GPL-2.0-or-later. Contributors must accept the terms of the Developer Certificate of Origin (DCO) by adding a Signed-off-by: line to each commit message. The software on the development branch continues to be provided under Apache-2.0. Update README.md, CONTRIBUTING.md and pull_request_template.md to explain the new licensing model. Add a copy of the DCO to the project.
