 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
