      ECHD-ECDSA if the only key exchange. Multiple reports. #310
    * Fix bug causing some handshakes to fail due to some non-fatal alerts not
      begin properly ignored. Found by mancha and Kasom Koht-arsa, #308
+   * mbedtls_x509_crt_verify(_with_profile)() now also checks the key type and

+     minimum key size for end-entity certificates with RSA keys. Found by
