+Deprecation
+-----------
+The AWS Encryption SDK CLI no longer supports Python 2 or Python 3.4

+or Python 3.4 can still use the 3.x line of the AWS Encryption SDK CLI,
+which will continue to receive security updates for the next 12 months, in accordance
+with our `Support Policy <https://github.com/aws/aws-encryption-sdk-cli/blob/master/SUPPORT_POLICY.rst>`__.
