It doesn't appear they have a CLA. The old license was BSD 3-clause, which states: > 1. Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer. > 2. Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution. And nowhere is that list to be found. So it appears Sentry is violating the license for external contributions.
