+Security
+   * Remove MBEDTLS_SSL_AEAD_RANDOM_IV option, because it was not compliant
+     with RFC5116 and could lead to session key recovery in very long TLS
+     sessions. (H. Bock, A. Zauner, S. Devlin, J. Somorovsky, P. Jovanovic -
+     "Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in TLS")
+   * Fix potential stack corruption in mbedtls_x509write_crt_der() and
+     mbedtls_x509write_csr_der() when the signature is copied to the buffer
+     without checking whether there is enough space in the destination. The
+     issue cannot be triggered remotely. (found by Jethro Beekman)

      when GCM is used. #441
    * Fix for key exchanges based on ECDH-RSA or ECDH-ECDSA which weren't
      enabled unless others were also present. Found by David Fernandez. #428
+   * Fixed cert_app sample program for debug output and for use when no root
+     certificates are provided.
+   * Fix conditional statement that would cause a 1 byte overread in

+   * Fixed pthread implementation to avoid unintended double initialisations
+     and double frees. (found by Niklas Amnebratt)
