+## [10.2.5] - 2020-08-15
+
+(ws) merge all ws_*.cpp files into a single one to speedup compilation
+
+## [10.2.4] - 2020-08-15
+
+(socket server) in the loop accepting connections, call select without a timeout on unix to avoid busy looping, and only wake up when a new connection happens
+
+## [10.2.3] - 2020-08-15
+
+(socket server) instead of busy looping with a sleep, only wake up the GC thread when a new thread will have to be joined, (we know that thanks to the ConnectionState OnSetTerminated callback
+
+## [10.2.2] - 2020-08-15
+
+(socket server) add a callback to the ConnectionState to be invoked when the connection is terminated. This will be used by the SocketServer in the future to know on time that the associated connection thread can be terminated.
+
+## [10.2.1] - 2020-08-15
+
+(socket server) do not create a select interrupt object everytime when polling for notifications while waiting for new connections, instead use a persistent one which is a member variable
+
+## [10.2.0] - 2020-08-14
+
+(ixwebsocket client) handle HTTP redirects
+
+## [10.2.0] - 2020-08-13
+
+(ws) upgrade to latest version of nlohmann json (3.9.1 from 3.2.0)
+
+## [10.1.9] - 2020-08-13
+
+(websocket proxy server) add ability to map different hosts to different websocket servers, using a json config file
+
+## [10.1.8] - 2020-08-12
+
+(ws) on macOS, with OpenSSL or MbedTLS, use /etc/ssl/cert.pem as the system certs
+
+## [10.1.7] - 2020-08-11
+
+(ws) -q option imply info log level, not warning log level

 (websocket server) Handle programmer error when the server callback is not registered properly (fix #227)

 ### Sending messages
 
-`websocket.send("foo")` will send a message.
+`WebSocketSendInfo result = websocket.send("foo")` will send a message.
 
-If the connection was closed and sending failed, the return value will be set to false.
+If the connection was closed, sending will fail, and the success field of the result object  will be set to false. There could also be a compression error in which case the compressError field will be set to true. The payloadSize field and wireSize fields will tell you respectively how much bytes the message weight, and how many bytes were sent on the wire (potentially compressed + counting the message header (a few bytes).
+
+There is an optional progress callback that can be passed in as the second argument. If a message is large it will be fragmented into chunks which will be sent independantly. Everytime the we can write a fragment into the OS network cache, the callback will be invoked. If a user wants to cancel a slow send, false should be returned from within the callback.
+
+Here is an example code snippet copied from the ws send sub-command. Each fragment weights 32K, so the total integer is the wireSize divided by 32K. As an example if you are sending 32M of data, uncompressed, total will be 1000. current will be set to 0 for the first fragment, then 1, 2 etc...
+
+```
+auto result =
+    _webSocket.sendBinary(serializedMsg, [this, throttle](int current, int total) -> bool {
+        spdlog::info("ws_send: Step {} out of {}", current + 1, total);
+
+        if (throttle)

 If you connect to ws://127.0.0.1:8008, the proxy will connect to ws://127.0.0.1:9000 and pass all traffic to this server.
 
+You can also use a more complex setup if you want to redirect to different websocket servers based on the hostname your client is trying to connect to. If you have multiple CNAME aliases that point to the same server.
+
+A JSON config file is used to express that mapping ; here connecting to echo.jeanserge.com will proxy the client to ws://localhost:8008 on the local machine (which actually runs ws echo_server), while connecting to bavarde.jeanserge.com will proxy the client to ws://localhost:5678 where a cobra python server is running. As a side note you will need a wildcard SSL certificate if you want to have SSL enabled on that machine.
+
+```json
+{
+        "remote_urls": {
+                "echo.jeanserge.com": "ws://localhost:8008",
+                "bavarde.jeanserge.com": "ws://localhost:5678"
+        }
+}
+```
+The --config_path option is required to instruct ws proxy_server to read that file.
