+HEAD
+
+0.6.0
+- MINOR BREAKING TRANSPORT POLICY CHANGE: Custom transport policies will now be
+  required to include a new method `void set_uri(uri_ptr u)`. An implementation
+  is not required. The stub transport policy includes an example stub method
+  that can be added to any existing custom transport policy to fulfill this
+  requirement. This does not affect anyone using the bundled transports or
+  configs.
+- MINOR BREAKING SOCKET POLICY CHANGE: Custom asio transport socket policies 
+  will now be required to include a new method `void set_uri(uri_ptr u)`. Like
+  with the transport layer, an implementation is not required. This does not 
+  affect anyone using the bundled socket policies.
+- MINOR BREAKING DEPENDENCY CHANGE: When using Boost versions greater than or 
+  equal to 1.49 in C++03 mode, `libboost-chrono` is needed now instead of 
+  `libboost-date_time`. Users with C++11 compilers or using Boost versions 1.48
+  and earlier are not affected. Note: This change affects the bundled unit test
+  suite.
+- Feature: WebSocket++ Asio transport policy can now be used with the standalone
+  version of Asio (1.8.0+) when a C++11 compiler and standard library are 
+  present. This means that it is possible now to use WebSocket++'s Asio
+  transport entirely without Boost. Thank you Robert Seiler for proof of concept
+  code that was used as a guide for this implementation. Fixes #324 
+- Feature: Adds a vectored/scatter-gather write handler to the iostream
+  transport.
+- Feature: Adds the ability to defer sending an HTTP response until sometime
+  after the `http_handler` is run. This allows processing of long running http
+  handlers to defer their response until it is ready without blocking the
+  network thread. references #425
+- Improvement: `echo_server_tls` has been update to demonstrate how to configure
+  it for Mozilla's recommended intermediate and modern TLS security profiles.
+- Improvement: `endpoint::set_timer` now uses a steady clock provided by 
+  `boost::chrono` or `std::chrono` where available instead of the non-monotonic
+  system clock. Thank you breyed for reporting. fixes #241
+- Improvement: Outgoing TLS connections to servers using the SNI extension to
+  choose a certificate will now work. Thank you moozzyk for reporting. 
+  Fixes #400
+- Improvement: Removes an unnecessary mutex lock in `get_con_from_hdl`.
+- Cleanup: Asio transport policy has been refactored to remove many Boost
+  dependencies. On C++03 compilers the `boost::noncopyable` dependency has been
+  removed and the `boost::date_time` dependency has been replaced with the newer
+  `boost::chrono` when possible. On C++11 compilers the `boost::aligned_storage`
+  and `boost::date_time` dependencies are gone, replaced with equivalent C++11
+  standard library features.
+- Bug: Fixes a potential dangling pointer and inconsistent error message
+  handling in `websocketpp::exception`. #432 Thank you Tom Swirly for the fix.
+
+0.5.1 - 2015-02-27
+- Bug: Fixes an issue where some frame data was counted against the max header
+  size limit, resulting in connections that included a lot of frame data
+  immediately after the opening handshake to fail.
+- Bug: Fix a typo in the name of the set method for `max_http_body_size`. #406
+  Thank you jplatte for reporting.
+
+0.5.0 - 2015-01-22
+- BREAKING UTILITY CHANGE: Deprecated methods `http::parser::parse_headers`,
+  `http::response::parse_complete`, and `http::request::parse_complete` have
+  been removed.
+- Security: Disabled SSLv3 in example servers.
+- Feature: Adds basic support for accessing HTTP request bodies in the http
+  handler. #181
+- Feature: Adds the ability to register a shutdown handler when using the
+  iostream transport. This provides a clean interface for triggering the shut
+  down of external sockets and other cleanup without hooking in to higher level
+  WebSocket handlers.
+- Feature: Adds the ability to register a write handler when using the iostream
+  transport. This handler can be used to handle transport output in place of
+  registering an ostream to write to.
+- Feature: Adds a new logging policy that outputs to syslog. #386 Thank you Tom
+  Hughes for submitting the initial version of this policy.
+- Improvement: Message payload logging now prints text for text messages rather
+  than binary.
+- Improvement: Overhaul of handshake state machine. Should make it impossible
+  for exceptions to bubble out of transport methods like `io_service::run`.
+- Improvement: Overhaul of handshake error reporting. Fail handler error codes
+  will be more detailed and precise. Adds new [fail] and [http] logging channels
+  that log failed websocket connections and successful HTTP connections
+  respectively. A new aggregate channel package, `alevel::access_core`, allows
+  enabling connect, disconnect, fail, and http together. Successful HTTP
+  connections will no longer trigger a fail handler.
+- Improvement: Ability to terminate connection during an http handler to cleanly
+  suppress the default outgoing HTTP response.
+- Documentation: Add Sending & Receiving Messages step to chapter one of the
+  `utility_client` tutorial. Update `utility_client` example to match.
+- Cleanup: Removes unused files & STL includes. Adds required STL includes.
+  Normalizes include order.
+- Bug: Fixes a fatal state error when a handshake response is completed
+  immediately after that handshake times out. #389
+- Bug: MinGW fixes; C++11 feature detection, localtime use. #393 Thank you
+  Schebb for reporting, code, and testing.
+- Bug: Fixes an issue where `websocketpp::exception::what()` could return an out
+  of scope pointer. #397 Thank you fabioang for reporting.
+- Bug: Fixes an issue where endpoints were not reset properly after a call to
+  `endpoint::listen` failed. #390 Thank you wyyqyl for reporting.

+ * each client containing an integer count. This example can be used as the
+ * basis for programs that expose a stream of telemetry data for logging,
+ * dashboards, etc.
+ *
+ * This example uses the timer based concurrency method and is self contained
+ * and singled threaded. Refer to telemetry client for an example of a similar
+ * telemetry setup using threads rather than timers.
+ *
+ * This example also includes an example simple HTTP server that serves a web
+ * dashboard displaying the count. This simple design is suitable for use 
+ * delivering a small number of files to a small number of clients. It is ideal
+ * for cases like embedded dashboards that don't want the complexity of an extra
+ * HTTP server to serve static files.
+ *
+ * This design *will* fall over under high traffic or DoS conditions. In such
+ * cases you are much better off proxying to a real HTTP server for the http
+ * requests.

 ==========================
 
 WebSocket++ is a header only C++ library that implements RFC6455 The WebSocket
 Protocol. It allows integrating WebSocket client and server functionality into
 C++ programs. It uses interchangeable network transport modules including one
-based on C++ iostreams and one based on Boost Asio.
+based on raw char buffers, one based on C++ iostreams, and one based on Asio 
+(either via Boost or standalone). End users can write additional transport
+policies to support other networking or event libraries as needed.

 _Sending and receiving messages_
 
-- Sending a messages
-- terminology: WebSocket opcodes, text vs binary messages
-- Receiving a message
+This step adds a command to send a message on a given connection and updates the show command to print a transcript of all sent and received messages for that connection.
+
+> ###### Terminology: WebSocket message types (opcodes)
+> WebSocket messages have types indicated by their opcode. The protocol currently specifies two different opcodes for data messages, text and binary. Text messages represent UTF8 text and will be validated as such. Binary messages represent raw binary bytes and are passed through directly with no validation. 
+>
+> WebSocket++ provides the values `websocketpp::frame::opcode::text` and `websocketpp::frame::opcode::binary` that can be used to direct how outgoing messages should be sent and to check how incoming messages are formatted.
+
+#### Sending Messages
+
+Messages are sent using `endpoint::send`. This is a thread safe method that may be called from anywhere to queue a message for sending on the specified connection. There are three send overloads for use with different scenarios. 
+
+Each method takes a `connection_hdl` to indicate which connection to send the message on as well as a `frame::opcode::value` to indicate which opcode to label the message as. All overloads are also available with an exception free varient that fills in a a status/error code instead of throwing.
+
+The first overload, `connection_hdl hdl, std::string const & payload, frame::opcode::value op`, takes a `std::string`. The string contents are copied into an internal buffer and can be safely modified after calling send.
+
+The second overload, `connection_hdl hdl, void const * payload, size_t len, frame::opcode::value op`, takes a void * buffer and length. The buffer contents are copied and can be safely modified after calling send.
+
+The third overload, `connection_hdl hdl, message_ptr msg`, takes a WebSocket++ `message_ptr`. This overload allows a message to be constructed in place before the call to send. It also may allow a single message buffer to be sent multiple times, including to multiple connections, without copying. Whether or not this actually happens depends on other factors such as whether compression is enabled. The contents of the message buffer may not be safely modified after being sent.
+
+> ###### Terminology: Outgoing WebSocket message queueing & flow control
+> In many configurations, such as when the Asio based transport is in use, WebSocket++ is an asynchronous system. As such the `endpoint::send` method may return before any bytes are actually written to the outgoing socket. In cases where send is called multiple times in quick succession messages may be coalesced and sent in the same operation or even the same TCP packet. When this happens the message boundaries are preserved (each call to send will produce a separate message).
+>
+> In the case of applications that call send from inside a handler this means that no messages will be written to the socket until that handler returns. If you are planning to send many messages in this manor or need a message to be written on the wire before continuing you should look into using multiple threads or the built in timer/interrupt handler functionality.
+>
+> If the outgoing socket link is slow messages may build up in this queue. You can use `connection::get_buffered_amount` to query the current size of the written message queue to decide if you want to change your sending behavior.
+
+#### Add send method to `websocket_endpoint`
+
+Like the close method, send will start by looking up the given connection ID in the connection list.  Next a send request is sent to the connection's handle with the specified WebSocket message and the text opcode. Finally, we record the sent message with our connection metadata object so later our show connection command can print a list of messages sent.
+
+```cpp
+void send(int id, std::string message) {
+    websocketpp::lib::error_code ec;
+    
+    con_list::iterator metadata_it = m_connection_list.find(id);
+    if (metadata_it == m_connection_list.end()) {
+        std::cout << "> No connection found with id " << id << std::endl;
+        return;
+    }
+    
+    m_endpoint.send(metadata_it->second->get_hdl(), message, websocketpp::frame::opcode::text, ec);
+    if (ec) {
+        std::cout << "> Error sending message: " << ec.message() << std::endl;
+        return;
+    }
+    
+    metadata_it->second->record_sent_message(message);
+}
+```
+
+#### Add send option to the command loop and help message
+
+A send option is added to the command loop. It takes a connection ID and a text message to send. An entry is also added to the help system to describe how the new command may be used.
+
+```cpp
+else if (input.substr(0,4) == "send") {
+    std::stringstream ss(input);
+        
+        std::string cmd;
+        int id;
+        std::string message = "";
+        
+        ss >> cmd >> id;
+        std::getline(ss,message);
+        
+        endpoint.send(id, message);
+}
+```
+
+#### Add glue to `connection_metadata` for storing sent messages
+
+In order to store messages sent on this connection some code is added to `connection_metadata`. This includes a new data member `std::vector<std::string> m_messages` to keep track of all messages sent and received as well as a method for adding a sent message in that list:
+
+```cpp
+void record_sent_message(std::string message) {
+    m_messages.push_back(">> " + message);
+}
+```
+
+Finally the connection metadata output operator is updated to also print a list of processed messages:
+
+```cpp
+out << "> Messages Processed: (" << data.m_messages.size() << ") \n";
+
+std::vector<std::string>::const_iterator it;
+for (it = data.m_messages.begin(); it != data.m_messages.end(); ++it) {
+    out << *it << "\n";
+}
+```
+
+#### Receiving Messages
+
+Messages are received by registering a message handler. This handler will be called once per message received and its signature is `void on_message(websocketpp::connection_hdl hdl, endpoint::message_ptr msg)`. The `connection_hdl`, like the similar parameter from the other handlers is a handle for the connection that the message was received on. The `message_ptr` is a pointer to an object that can be queried for the message payload, opcode, and other metadata. Note that the message_ptr type, as well as its underlying message type, is dependent on how your endpoint is configured and may be different for different configs.
+
+#### Add a message handler to method to `connection_metadata`
+
+The message receiving behave that we are implementing will be to collect all messages sent and received and to print them in order when the show connection command is run. The sent messages are already being added to that list. Now we add a message handler that pushes received messages to the list as well. Text messages are pushed as-is. Binary messages are first converted to printable hexadecimal format.
+
+```cpp
+void on_message(websocketpp::connection_hdl hdl, client::message_ptr msg) {
+    if (msg->get_opcode() == websocketpp::frame::opcode::text) {
+        m_messages.push_back(msg->get_payload());
+    } else {
+        m_messages.push_back(websocketpp::utility::to_hex(msg->get_payload()));
+    }
+}
+```
+
+In order to have this handler called when new messages are received we also register it with our connection. Note that unlike most other handlers, the message handler has two parameters and thus needs two placeholders.
+
+```cpp
+con->set_message_handler(websocketpp::lib::bind(
+    &connection_metadata::on_message,
+    metadata_ptr,
+    websocketpp::lib::placeholders::_1,
+    websocketpp::lib::placeholders::_2
+));
+```
+
+#### Build
+
+There are no changes to the build instructions from step 5
+
+#### Run
+
+In this example run we are connecting to the WebSocket++ example echo_server. This server will repeat any message we send back to it. You can also try testing this with the echo server at `ws://echo.websocket.org` with similar results.
+
+```
+Enter Command: connect ws://localhost:9002
+> Created connection with id 0
+Enter Command: send 0 example message
+Enter Command: show 0
+> URI: ws://localhost:9002
+> Status: Open
+> Remote Server: WebSocket++/0.4.0
+> Error/close reason: N/A
+> Messages Processed: (2)
+>>  example message
+<<  example message
+```
 
 ### Step 7
 
 _Using TLS / Secure WebSockets_
 
+- Change the includes
+- link to the new library dependencies
+- Switch the config
+- add the `tls_init_handler`
+- configure the SSL context for desired security level
+- mixing secure and non-secure connections in one application.
