 = mbed TLS 2.y.0 released YYYY-MM-DD
 
 Features
-   * Add support for restartable ECC operations, controlled by
-     MBEDTLS_ECP_RESTARTABLE (disabled by default), using new xxx_restartable
-     functions in ECP, ECDSA, PK, and using existing functions in ECDH.
+   * Add support for restartable ECC operations, enabled by
+     MBEDTLS_ECP_RESTARTABLE (disabled by default) at compile time and
+     mbedtls_ecp_set_max_ops() at runtime, using new xxx_restartable functions
+     in ECP, ECDSA, PK, and using existing functions in ECDH and SSL
+     (currently only implemented client-side, for ECDHE-ECDSA ciphersuites
+     with TLS 1.2, including client authentication).
+     TEMPORARY NOTE: server authentication currently not supported (WIP).
+     For now, MUST be disabled by calling
+     mbedtls_ssl_conf_authmode( MBEDTLS_SSL_VERIFY_NONE )
+     (or blocking ECC operations will happen)
