(CI) try to build Linux on Ubuntu Bionic

- ws cobra_subscribe has a new -q (quiet) option
- ws cobra_subscribe knows to and display msg stats (count and # of messages received per second)
- ws cobra_subscribe, cobra_to_statsd and cobra_to_sentry commands have a new option, --filter to restrict the events they want to receive

+# Changelog
+All notable changes to this project will be documented in this file.
+
+## [5.0.3] - 2019-08-14
+- CobraMetricThreadedPublisher _enable flag is an atomic, and CobraMetricsPublisher is enabled by default
+
+## [5.0.2] - 2019-08-01
+- ws cobra_subscribe has a new -q (quiet) option
+- ws cobra_subscribe knows to and display msg stats (count and # of messages received per second)
+- ws cobra_subscribe, cobra_to_statsd and cobra_to_sentry commands have a new option, --filter to restrict the events they want to receive
+
+## [5.0.1] - 2019-07-25
+- ws connect command has a new option to send in binary mode (still default to text)
+- ws connect command has readline history thanks to libnoise-cpp. Now ws connect one can use using arrows to lookup previous sent messages and edit them
+
+## [5.0.0] - 2019-06-23
+### Changed
+- New HTTP server / still very early. ws gained a new command, httpd can run a simple webserver serving local files.
+- IXDNSLookup. Uses weak pointer + smart_ptr + shared_from_this instead of static sets + mutex to handle object going away before dns lookup has resolved
+- cobra_to_sentry / backtraces are reversed and line number is not extracted correctly
+- 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

 ## Introduction
 
-[*WebSocket*](https://en.wikipedia.org/wiki/WebSocket) is a computer communications protocol, providing full-duplex and bi-directionnal communication channels over a single TCP connection. *IXWebSocket* is a C++ library for client and server Websocket communication, and for client HTTP communication. The code is derived from [easywsclient](https://github.com/dhbaird/easywsclient) and from the [Satori C SDK](https://github.com/satori-com/satori-rtm-sdk-c). It has been tested on the following platforms.

 CMakefiles for the library and the examples are available. This library has few dependencies, so it is possible to just add the source files into your project. Otherwise the usual way will suffice.

 There is a unittest which can be executed by typing `make test`.

+Options for building:
+
+* `-DUSE_TLS=1` will enable TLS support
+* `-DUSE_MBED_TLS=1` will use [mbedlts](https://tls.mbed.org/) for the TLS support (default on Windows)
+* `-DUSE_WS=1` will build the ws interactive command line tool

+### vcpkg
+
+It is possible to get IXWebSocket through Microsoft [vcpkg](https://github.com/microsoft/vcpkg).

+```
+vcpkg install ixwebsocket

+### Conan
+
+Support for building with conan was contributed by Olivia Zoe (thanks !). The package name to reference is `IXWebSocket/5.0.0@LunarWatcher/stable`. The package is in the process to be published to the official conan package repo, but in the meantime, it can be accessed by adding a new remote

+cpp-linenoise
+=============
+
+Multi-platfrom (Unix, Windows) C++ header-only linenoise-based readline library.
+
+This library gathered code from following excellent libraries, clean it up, and put it into a C++ header file for convenience.
+
+ * `linenoise.h` and `linenose.c` ([antirez/linenoise](https://github.com/antirez/linenoise))
+ * `ANSI.c` ([adoxa/ansicon](https://github.com/adoxa/ansicon))
+ * `Win32_ANSI.h` and `Win32_ANSI.c` ([MSOpenTech/redis](https://github.com/MSOpenTech/redis))
+
+The licenses for the libraries are included in `linenoise.hpp`.
+
+Usage
+-----
+
+```c++
+#include "linenoise.hpp"
+
+...
+
+const auto path = "history.txt";
+
+// Setup completion words every time when a user types
+linenoise::SetCompletionCallback([](const char* editBuffer, std::vector<std::string>& completions) {
+    if (editBuffer[0] == 'h') {
+        completions.push_back("hello");
+        completions.push_back("hello there");
+    }
+});
+
+// Enable the multi-line mode
+linenoise::SetMultiLine(true);
+
+// Set max length of the history
+linenoise::SetHistoryMaxLen(4);
+
+// Load history
+linenoise::LoadHistory(path);
+
+while (true) {
+    // Read line
+    std::string line;
+    auto quit = linenoise::Readline("hello> ", line);
+
+    if (quit) {
+        break;
+    }
+
+    cout <<  "echo: '" << line << "'" << endl;
+
+    // Add text to history
+    linenoise::AddHistory(line.c_str());
+}
+
+// Save history
+linenoise::SaveHistory(path);
+```
+
+API
+---
+
+```c++
+namespace linenoise;
+
+std::string Readline(const char* prompt);
+
+void SetMultiLine(bool multiLineMode);
+
+typedef std::function<void (const char* editBuffer, std::vector<std::string>& completions)> CompletionCallback;
+
+void SetCompletionCallback(CompletionCallback fn);
+
+bool SetHistoryMaxLen(size_t len);
+
+bool LoadHistory(const char* path);
+
+bool SaveHistory(const char* path);
+
+bool AddHistory(const char* line);
+
+const std::vector<std::string>& GetHistory();
+```
