+
+pw_rpc
+------
+``pw_rpc`` clients will once again accept unsolicited responses from ``pw_rpc``
+servers that were built prior to September 2022. Unsolicited responses, also
+known as "open" requests, let a server send a message to a client prior to the
+client sending a request. This change fixed an incompatibility in which
+``pw_rpc`` clients built after September 2022 would not accept unsolicited
+responses from servers built before September 2022 (specifically,
+change `#109077 <https://pwrev.dev/109077>`_).
