NNG_OPT_WS_OPT_WS_REQUEST_HEADERS and NNG_OPT_WS_RESPONSE_HEADERS have been removed.
Just convert any use of them to NNG_OPT_WS_REQUEST_HEADERS or
NNG_OPT_WS_RESPONSE_HEADERS as appropriate.
+The support for configuring TLS via NNG_TLS_AUTH_MODE, NNG_OPT_TLS_CA_FILE, NNG_OPT_TLS_SERVER_NAME,
+and similar has been removed. Instead configuration must be performed by allocating
+a nng_tls_config object, and then setting fields on it using the appropriate functions,
+after which it may be configured on a listener or dialer using the NNG_OPT_TLS_CONFIG option.
The previously deprecated nng_pipe_getopt_xxx family of functions is removed.
Applications should use nng_pipe_get and related functions instead.
