v0.8.2 Changes
April 19, 2020
📚 This is a bug fix patch that fixes a major issue affecting compatibility with newer versions of the Asio library (including the one bundled in Boost 1.70 and higher). It also includes some documentation, cmake, and OpenSSL compatibility fixes.

Details
- Compatibility : Removes the use of make_shared in a number of cases where
  it would be incompatible with newer versions of ASIO. Thank you Stefan
  Floeren for the patch. #810 #814 #862 #843 #794 #808
- Examples : Update print_client_tls example to remove use of deprecated
  OpenSSL functions.
- CMake : Update cmake installer to better handle dependencies when using
  🍎 g++ on MacOS. Thank you Luca Palano for reporting and a patch. #831
- CMake : Update cmake installer to use a variable for the include directory
  improving the ability of the install to be customized. Thank you Schrijvers
  Luc and Gianfranco Costamanga for reporting and a patch. #842
v0.8.1 Changes
July 16, 2018
✅ This is a bug fix patch to fix a major test suite regression introduced in 0.8.0 and adjust installation behavior to make downstream packaging easier.

Note: There are no changes to the library itself, only to the test and installation systems.

Details
- ✅ Test Suite: Adjust test suite to match behavior introduced in 0.8.0. Thank
  you Gianfranco Costamagna for reporting and a patch. #731
- CMake: Update cmake installer to only install library files globally.
  Thank you Gianfraco Costamanga for reporting and a patch. #732
v0.8.0 Changes
July 12, 2018
- Examples : Add print_client example. This demonstrates a minimal non-TLS
  🖨 client that connects to a server and prints out the messages it receives.
- Examples : Add print_client_tls example. This demonstrates a minimal TLS
  👍 client, including basic support via Asio+OpenSSL for certificate chain
  and hostname verification.
- 🔋 Feature : Add getter for all headers to the HTTP parsers. This allows a
  wrapping library to enumerate all headers to send upstream. Thank you Jupp
  Müller for reporting and an initial pull request.
- 👌 Improvement : Move the socket_init_handler to execute as a part of init_asio
  rather than connection pre_init. This allows setting of socket options prior
  to the bind/listen/accept system calls. Thank you ChristianRobl3D for
  reporting #530.
- 👌 Improvement : Timers in transport integration tests should only fail if their
  ✅ own test times out, rather than any test. #643 Thank you Alex Korotkin for
  reporting and a patch.
- 👌 Improvement : Preserve transport layer error codes in more cases, particularly
  during calls to endpoint::listen. #652 Thank you vadz for reporting and
  patches.
- Compatibility : Make sure the chrono library used by Boost/Asio is in sync
  with what the websocketpp is using. Thank you Flow86 for reporting and a
  patch.
- Compatibility : Update telemetry_client to use a slightly more cross platform
  🏁 method of sleeping. Should work on windows now. Thank you Meir Yanovich for
  reporting.
- Compatibility : Updated permessage-deflate support to reflect that the zlib
  👍 library does not actually support a sliding window size of 256 bits.
  🏁 WebSocket++ will no longer negotiate 256 bit deflate windows. If the user
  of the library tries to request a 256 bit window a 512 bit window will be
  specified instead (This was the previous behavior). #596 #653 Thank you
  Vinnie Falco and Gianfranco Costamagna for reporting.
- Compatibility : Better error handling and logging in cases where extension
  📜 requests parse correctly but negotiation fails.
- Compatibility : Removed custom handling of SSL_R_SHORT_READ error condition.
  This error code no longer exists in modern versions of OpenSSL and causes
  🏗 a build error. It wasn't being used for anything particularly important
  (slightly improving error reporting) and there isn't a great replacement.
  #599 Thank you Gianfranco Costamagna for reporting.
- Compatibility : Add missing <stdint> headers. Fixes issues with g++ 5.4.0.
  #638 Thank you Alex Korotkin for reporting and a patch.
- Compatibility : Remove the use of std::auto_ptr and std::binary_function
  🏗 from builds with C++11 or later. These features are deprecated and were
  ✂ removed entirely in C++17. This change allows building WebSocket++ on
  C++17 compilers. #592 Thank you Michal Fojtak for reporting and a patch
- Compatibility : Add 1014 close code and adds missing descriptions for codes
  1012 and 1013. #589 Thank you jbwdevries and ronneke1996 for reporting and
  patches.
- Compatibility : Add hooks to support mingw-std-threads C++11 thread and mutex
  polyfill library as an alternative to Boost. #608 Thank you Peter Taylor for
  reporting and an initial patch.
- Compatibility : Changed the handshake connection token to 'Upgrade' from
  ⬆️ 'upgrade'. Technically this header is supposed to be processed case
  💻 insensitively. In practice, there are browsers (such as Edge) that don't do
  this and they tend to use the uppercase value used as an example in RFC6455.
  Thank you Johann Bauer for reporting and a patch. #727
- 🐛 Bug : Store loggers in shared pointers to avoid crashes related to connections
  🔊 trying to write logs entries after their respective endpoint has been
  deallocated. Thank you Thalhammer for reporting and Jupp Müller for the
  patch. #539 #501
- 🐛 Bug : Change default listen backlog from 0 to socket_base::max_connections.
  #549. Thank you derwassi and zwelab for reporting and na1pir for providing
  access to hardware to debug the issue.
- 🐛 Bug : Fix a crash in the accept loop when get_connection fails. #551 Thank you
  Walter Gray for a patch.
- 🐛 Bug/Documentation : Fix incorrect example code that used
  👻 websocketpp::lib::error_code instead of websocketpp::exception. Thank you
  heretic13 for reporting
- 🐛 Bug : Fix uninitialized shared pointer in Asio transport test suite. #647
  Thank you Alex Korotkin for reporting and a patch.
- 🐛 Bug : Fix a thread safety issue in the permessage-deflate extension that
  caused message corruption when sending compressed messages from a different
  thread than the main I/O thread. #615 Thank you KyleNyenhuis and Pieter De
  Gendt for reporting and a patch.
- 🐛 Bug : Fix an undefined behavior issue performing a 64 bit wide shift on a 64
  bit value. #636 Thank you Gregor Jasny for reporting and a patch
- 🐛 Bug : Fix some compile issues with ASIO_STANDALONE. #662 #665 Thank you
  chronoxor and Guillaume Egles for reporting and patches.
v0.7.0 Changes
February 22, 2016
- MINOR BREAKING SOCKET POLICY CHANGE : Asio transport socket policy method cancel_socket will now return lib::asio::error_code instead of void. Custom Asio transport socket policies will need to be updated accordingly. This does not affect anyone using the bundled socket policies.
- 🔋 Feature : Basic support for the permessage-deflate extension. #344
- 🔋 Feature : Allow accessing the local endpoint when using the Asio transport. This allows inspection of the address and port in cases where they are chosen by the operating system rather than the user. Thank you Andreas Weis and Muzahid Hussain for reporting and related code. #458
- 🔋 Feature : Add support for subprotocols in Hybi00. Thank you Lukas Obermann for reporting and a patch. #518
- 👌 Improvement : Better automatic std::chrono feature detection for Visual Studio
- 👌 Improvement : Major refactoring to bundled CMake build system. CMake can now be used to build all of the examples and the test suite. Thank you Thijs Wenker for a significant portion of this code. #378, #435, #449
- 👌 Improvement : In build environments where lib::error_code and lib::asio::error_code match (such as using boost::asio with boost::system_error or standalone asio with std::system_error, transport errors are passed through natively rather than being reported as a translated pass_through error type.
- 👌 Improvement : Add a get_transport_error method to Asio transport connections to allow retrieving a machine readable native transport error.
- 👌 Improvement : Add connection::get_response, connection::get_response_code, and connection::get_response_msg methods to allow accessing additional information about the HTTP responses that WebSocket++ sends. #465 Thank youFlow86 for reporting.
- 👌 Improvement : Removes use of empty strings ("") in favor of string::clear() and string::empty(). This avoids generating unnecessary temporary objects. #468 Thank you Vladislav Yaroslavlev for reporting and a patch.
- 📚 Documentation : Adds an example demonstrating the use of external io_service
- 📚 Documentation : Adds a simple echo_client example.
- 📚 Documentation : Begins migration of the web based user manual into Doxygen.
- 🐛 Bug : Fix memory leak when init_asio produces an error. #454 Thank you Mark Grimes for reporting and fixing.
- 🐛 Bug : Fix crash when processing a specially crafted HTTP header. Thank you Eli Fidler for reporting, test cases, and a patch. #456
- 🐛 Bug : Fix an issue where standalone Asio builds that use TLS would not compile due to lingering boost code. #448 Thank you mjsp for reporting
- 🐛 Bug : Fix an issue where canceling a socket could throw an exception on some older Windows XP platforms. It now prints an appropriate set of log messages instead. Thank you Thijs Wenker for reporting and researching solutions. #460
- 🐛 Bug : Fix an issue where deferred HTTP connections that start sending a very long response before their HTTP handler ends would result in a second set of HTTP headers being injected into the output. Thank you Kevin Smith for reporting and providing test case details. #443
- 🐛 Bug : Fix an issue where the wrong type of strand was being created. Thank you Bastien Brunnenstein for reporting and a patch. #462
- 🐛 Bug : Fix an issue where TLS includes were broken for Asio Standalone builds. Thank you giachi and Bastien Brunnenstein for reporting. #491
- 🐛 Bug : Remove the use of cached read and write handlers in the Asio transport. This feature caused memory leaks when the io_service the connection was running on was abruptly stopped. There isn't a clean and safe way of using this optimization without global state and the associated locks. The locks perform worse. Thank you Xavier Gibert for reporting, test cases, and code. Fixes #490.
- 🐛 Bug : Fix a heap buffer overflow when checking very short URIs. Thank you Xavier Gibert for reporting and a patch #524
- Compatibility : Fixes a number of build & config issues on Visual Studio 2015
- Compatibility : Removes non-standards compliant masking behavior. #395, #469
- Compatibility : Replace deprecated use of auto_ptr on systems where unique_ptr is available.
v0.6.0 Changes
June 02, 2015
- 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.
v0.6.0-permessage Changes
June 07, 2015
📚 This is a companion release to WebSocket++/0.6.0 with support for the upcoming permessage-deflate WebSocket compression extension. Support is complete except for fine tuning documentation.

🚀 If no major issues are encountered with this pre-release version, the next mainline release of WebSocket++ (likely 0.7.x) will include support for permessage-deflate.
v0.5.1 Changes
February 27, 2015
- 🐛 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.
v0.5.0 Changes
January 22, 2015
- 💥 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
  0️⃣ 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.
v0.4.0 Changes
November 04, 2014
- 💥 BREAKING API CHANGE : All WebSocket++ methods now throw an exception of type
  👻 websocketpp::exception which derives from std::exception. This normalizes
  👻 all exception types under the standard exception hierarchy and allows
  WebSocket++ exceptions to be caught in the same statement as others. The error
  👻 code that was previously thrown is wrapped in the exception object and can be
  👻 accessed via the websocketpp::exception::code() method.
- 💥 BREAKING API CHANGE : Custom logging policies have some new required
  constructors that take generic config settings rather than pointers to
  🌲 std::ostreams. This allows writing logging policies that do not involve the
  🌲 use of std::ostream. This does not affect anyone using the built in logging
  policies.
- 💥 BREAKING UTILITY CHANGE : websocketpp::lib::net::htonll and
  🛠 websocketpp::lib::net::ntohll have been prefixed with an underscore to avoid
  conflicts with similarly named macros in some operating systems. If you are
  using the WebSocket++ provided 64 bit host/network byte order functions you
  🛠 will need to switch to the prefixed versions.
- 💥 BREAKING UTILITY CHANGE : The signature of base64_encode has changed from
  websocketpp::base64_encode(unsigned char const *, unsigned int) to
  websocketpp::base64_encode(unsigned char const *, size_t).
- 💥 BREAKING UTILITY CHANGE : The signature of sha1::calc has changed from
  websocketpp::sha1::calc(void const *, int, unsigned char *) to
  websocketpp::sha1::calc(void const *, size_t, unsigned char *)
- 🔋 Feature : Adds incomplete minimal_server and minimal_client configs that
  🏗 can be used to build custom configs without pulling in the dependencies of
  core or core_client. These configs will offer a stable base config to
  future-proof custom configs.
- 👌 Improvement : Core library no longer has std::iostream as a dependency.
  🌲 std::iostream is still required for the optional iostream logging policy and
  iostream transport.
- 🐛 Bug : C++11 Chrono support was being incorrectly detected by the boost_config
  header. Thank you Max Dmitrichenko for reporting and a patch.
- 🐛 Bug : use of std::put_time is now guarded by a unique flag rather than a
  chrono library flag. Thank you Max Dmitrichenko for reporting.
- 🐛 Bug : Fixes non-thread safe use of std::localtime. #347 #383
- Compatibility : Adjust usage of std::min to be more compatible with systems
  that define a min(...) macro.
- Compatibility : Removes unused parameters from all library, test, and example
  code. This assists with those developing with -Werror and -Wunused-parameter
  #376
- Compatibility : Renames ntohll and htonll methods to avoid conflicts with
  platform specific macros. #358 #381, #382 Thank you logotype, unphased,
  svendjo
- Cleanup : Removes unused functions, fixes variable shadow warnings, normalizes
  ✅ all whitespace in library, examples, and tests to 4 spaces. #376
v0.3.0 Changes
August 09, 2014
- 🔋 Feature : Adds start_perpetual and stop_perpetual methods to asio transport
  These may be used to replace manually managed asio::io_service::work objects
- 🔋 Feature : Allow setting pong and handshake timeouts at runtime.
- 🔋 Feature : Allows changing the listen backlog queue length.
- 🔋 Feature : Split tcp init into pre and post init.
- 🔋 Feature : Adds URI method to extract query string from URI. Thank you Banaan
  for code. #298
- 🔋 Feature : Adds a compile time switch to asio transport config to disable
  certain multithreading features (some locks, asio strands)
- 🔋 Feature : Adds the ability to pause reading on a connection. Paused connections
  will not read more data from their socket, allowing TCP flow control to work
  without blocking the main thread.
- 🔋 Feature : Adds the ability to specify whether or not to use the SO_REUSEADDR
  0️⃣ TCP socket option. The default for this value has been changed from true to
  false.
- 🔋 Feature : Adds the ability to specify a maximum message size.
- 🔋 Feature : Adds close::status::get_string(...) method to look up a human
  readable string given a close code value.
- 🔋 Feature : Adds connection::read_all(...) method to iostream transport as a
  convenience method for reading all data into the connection buffer without the
  end user needing to manually loop on read_some.
- 👌 Improvement : Open, close, and pong timeouts can be disabled entirely by
  setting their duration to 0.
- 👌 Improvement : Numerous performance improvements. Including: tuned default
  buffer sizes based on profiling, caching of handler binding for async
  reads/writes, non-malloc allocators for read/write handlers, disabling of a
  number of questionably useful range sanity checks in tight inner loops.
- 👌 Improvement : Cleaned up the handling of TLS related errors. TLS errors will
  now be reported with more detail on the info channel rather than all being
  tls_short_read or pass_through. In addition, many cases where a TLS short
  read was in fact expected are no longer classified as errors. Expected TLS
  short reads and quasi-expected socket shutdown related errors will no longer
  be reported as unclean WebSocket shutdowns to the application. Information
  about them will remain in the info error channel for debugging purposes.
- 👌 Improvement : start_accept and listen errors are now reported to the caller
  👻 either via an exception or an ec parameter.
- 👌 Improvement : Outgoing writes are now batched for improved message throughput
  and reduced system call and TCP frame overhead.
- 🐛 Bug : Fix some cases of calls to empty lib::function objects.
- 🐛 Bug : Fix memory leak of connection objects due to cached handlers holding on to
  reference counted pointers. #310 Thank you otaras for reporting.
- 🐛 Bug : Fix issue with const endpoint accessors (such as get_user_agent) not
  compiling due to non-const mutex use. #292 Thank you logofive for reporting.
- 🐛 Bug : Fix handler allocation crash with multithreaded io_service.
- 🐛 Bug : Fixes incorrect whitespace handling in header parsing. #301 Thank you
  Wolfram Schroers for reporting
- 🐛 Bug : Fix a crash when parsing empty HTTP headers. Thank you Thingol for
  reporting.
- 🐛 Bug : Fix a crash following use of the stop_listening function. Thank you
  Thingol for reporting.
- 🐛 Bug : Fix use of variable names that shadow function parameters. The library
  should compile cleanly with -Wshadow now. Thank you giszo for reporting. #318
- 🐛 Bug : Fix an issue where set_open_handshake_timeout was ignored by server
  code. Thank you Robin Rowe for reporting.
- 🐛 Bug : Fix an issue where custom timeout values weren't being propagated from
  endpoints to new connections.
- 🐛 Bug : Fix a number of memory leaks related to server connection failures. #323
  #333 #334 #335 Thank you droppy and aydany for reporting and patches.
  reporting.
- Compatibility : Fix compile time conflict with Visual Studio's MIN/MAX macros.
  Thank you Robin Rowe for reporting.
- 📚 Documentation : Examples and test suite build system now defaults to clang on
  OS X
