+   * The new functions mbedtls_ctr_drbg_update_ret() and
+     mbedtls_hmac_drbg_update_ret() are similar to mbedtls_ctr_drbg_update()
+     and mbedtls_hmac_drbg_update() respectively, but the new functions
+     report errors whereas the old functions return void. We recommend that
+     applications use the new functions.
