+
+## [4.0.0] - 2019-06-09
+### Changed

+- WebSocketMessage sets a new binary field, which tells whether the received incoming message is binary or text
+- WebSocket::send takes a third arg, binary which default to true (can be text too)
+- WebSocket callback only take one object, a const ix::WebSocketMessagePtr& msg
+- Add explicite WebSocket::sendBinary
+- New headers + WebSocketMessage class to hold message data, still not used across the board
+- Add test/compatibility folder with small servers and clients written in different languages and different libraries to test compatibility.
+- ws echo_server has a -g option to print a greeting message on connect
+- IXSocketMbedTLS: better error handling in close and connect
+
+## [3.1.2] - 2019-06-06
+### Added
+- ws connect has a -x option to disable per message deflate
+- Add WebSocket::disablePerMessageDeflate() option.
+
+## [3.0.0] - 2019-06-xx
+### Changed
