 # Changelog
+
 All changes to this project will be documented in this file.
 
+## [10.1.7] - 2020-08-11
+
+(ws) -q option imply info log level, not warning log level
+
+## [10.1.6] - 2020-08-06
+
+(websocket server) Handle programmer error when the server callback is not registered properly (fix #227)
+
+## [10.1.5] - 2020-08-02
+
+(ws) Add a new ws sub-command, push_server. This command runs a server which sends many messages in a loop to a websocket client. We can receive above 200,000 messages per second (cf #235).
+
+## [10.1.4] - 2020-08-02
+
+(ws) Add a new ws sub-command, echo_client. This command sends a message to an echo server, and send back to a server whatever message it does receive. When connecting to a local ws echo_server, on my MacBook Pro 2015 I can send/receive around 30,000 messages per second. (cf #235)
+
+## [10.1.3] - 2020-08-02
+
+(ws) ws echo_server. Add a -q option to only enable warning and error log levels. This is useful for bench-marking so that we do not print a lot of things on the console. (cf #235)
+
+## [10.1.2] - 2020-07-31
+
+(build) make using zlib optional, with the caveat that some http and websocket features are not available when zlib is absent
+
+## [10.1.1] - 2020-07-29
+
+(websocket client) onProgressCallback not called for short messages on a websocket (fix #233)
+
+## [10.1.0] - 2020-07-29
+
+(websocket client) heartbeat is not sent at the requested frequency (fix #232)
+
+## [10.0.3] - 2020-07-28

+## [10.0.1] - 2020-07-27
+
+(socket utility) move ix::getFreePort to ixwebsocket library
+
+## [10.0.0] - 2020-07-25
+
+(ixwebsocket server) change legacy api with 2 nested callbacks, so that the first api takes a weak_ptr<WebSocket> as its first argument
+
+## [9.10.7] - 2020-07-25
+
+(ixwebsocket) add WebSocketProxyServer, from ws. Still need to make the interface better.
+
+## [9.10.6] - 2020-07-24
+
+(ws) port broadcast_server sub-command to the new server API
+
+## [9.10.5] - 2020-07-24
+
+(unittest) port most unittests to the new server API
+
+## [9.10.3] - 2020-07-24

+## WebSocket Client performance
+
+We will run a client and a server on the same machine, connecting to localhost. This bench is run on a MacBook Pro from 2015. We can receive over 200,000 (small) messages per second, another way to put it is that it takes 5 micro-second to receive and process one message. This is an indication about the minimal latency to receive messages.
+
+### Receiving messages
+
+By using the push_server ws sub-command, the server will send the same message in a loop to any connected client.
+
+```
+ws push_server -q --send_msg 'yo'
+```
+
+By using the echo_client ws sub-command, with the -m (mute or no_send), we will display statistics on how many messages we can receive per second.
+
+```

 ### 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...

+The new API does not require to use 2 nested callbacks, which is a bit annoying. The real fix is that there was a memory leak due to a shared_ptr cycle, due to passing down a shared_ptr<WebSocket> down to the callbacks.

+The webSocket reference is guaranteed to be always valid ; by design the callback will never be invoked with a null webSocket object.
