+Security
+   * Fix authentication bypass in SSL/TLS: when auth_mode is set to optional,
+     ssl_get_verify_result() would incorrectly return 0 when the peer's
+     X.509 certificate chain had more than POLARSSL_X509_MAX_INTERMEDIATE_CA
+     (default: 8) intermediates, even when it was not trusted. Could be
+     triggered remotely on both sides. (With auth_mode set to required
+     (default), the handshake was correctly aborted.)
+
+API Changes
+   * Certificate verification functions now set flags to -1 in case the full
+     chain was not verified due to an internal error (including in the verify
+     callback) or chain length limitations.
+   * With authmode set to optional, handshake is now aborted if the
+     verification of the peer's certificate failed due to an overlong chain or
+     a fatal error in the vrfy callback.
