+## [unreleased] - 2019-06-09
+### Changed
+- mbedtls and zlib are searched with find_package, and we use the vendored version if nothing is found
+- travis CI uses g++ on Linux
+
+## [4.0.0] - 2019-06-09
+### Changed
+- WebSocket::send() sends message in TEXT mode by default
+- 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 explicit WebSocket::sendBinary method
+- 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
+- TLS, aka SSL works on Windows (websocket and http clients)
+- ws command line tool build on Windows
+- Async API for HttpClient
+- HttpClient API changed to use shared_ptr for response and request

+* On Windows TLS is not setup yet to validate certificates.
+* There is no convenient way to embed a ca cert.
 * No utf-8 validation is made when sending TEXT message with sendText()
 * Automatic reconnection works at the TCP socket level, and will detect remote end disconnects. However, if the device/computer network become unreachable (by turning off wifi), it is quite hard to reliably and timely detect it at the socket level using `recv` and `send` error codes. [Here](https://stackoverflow.com/questions/14782143/linux-socket-how-to-detect-disconnected-network-in-a-client-program) is a good discussion on the subject. This behavior is consistent with other runtimes such as node.js. One way to detect a disconnected device with low level C code is to do a name resolution with DNS but this can be expensive. Mobile devices have good and reliable API to do that.
 * The server code is using select to detect incoming data, and creates one OS thread per connection. This is not as scalable as strategies using epoll or kqueue.
