  • Add handler tracking locations to basic_stream.
  • Add handler tracking locations to http operations.

API Changes:

  • Previously, teardown and async_teardown of a websocket connection over SSL would only shut down the SSL layer, leaving the TCP layer connected. Now the SSL teardown will tear down both the SSL and TCP layers, cleanly shutting down the TCP connection and closing the socket. Should the client expect the TCP socket to remain connected, users will need to re-engineer their code.

Version 300:

  • Fix compile errors under Clang 3.4
  • Fix portability bug in websocket server sync example.

Version 299:

  • Fix race in http-crawl example.

Version 298:

  • Use dispatch/post free functions to be independent of executor concept.
  • New name for polymorphic executor. Trait for detecting new executors.
  • Handler invoke and allocation hooks are deprecated.

Version 297:

  • iless and iequal take part in Heterogeneous Lookup
  • Fix max compile error
  • Deprecate string_param (API Change)

API Changes:

  • string_param, which was previously the argument type when setting field values has been replaced by string_view. Because of this, it is no longer possible to set message field values directly as integrals.

    Users are required to convert numeric arguments to a string type prior to calling fields::set et. al.

    Beast provides the non-allocating to_static_string() function for this purpose.

    To set Content-Length field manually, call message::content_length.

Version 296:

  • Remove buffers_adapter.hpp (API Change)
  • Remove zlib error invalid_code_lenths(sic) (API Change)
  • Remove core/type_traits.hpp (API Change)
  • Remove reset function from flat_static_buffer (API Change)
  • Remove mutable_data_type from Dyanmic Buffers (API Change)
  • Remove deprecated lowest_layer from test::stream
  • Remove handler_pointer (API Change)
  • Remove websocket::role_type (API Change)
  • Remove accept_ex and handshake_ex variants (API Change)
  • Rename to BOOST_BEAST_ALLOW_DEPRECATED (API Change)

API Changes:

  • The file core/buffers_adapter.hpp has been removed along with the deprecated alias typename buffers_adapter. Affected programs should use core/buffers_adapator.hpp and the type buffers_adaptor.

  • The error code enum invalid_code_lenths was a synonym of invalid_code_lengths. Affected programs should be modified to use invalid_code_lengths.

  • The core/type_traits.hpp public header has been removed and along with it the type trait is_completion_handler. Beast uses the CompletionHandler correctness checks provided by Asio. In a c++20 environment, these convert to concept checks.

  • The reset function has been removed from flat_static_buffer. Use the clear function instead.

  • Code that depends on mutable_data_type should be refactored to use mutable_buffers_type. Classes affected are:

    • buffers_adaptor
    • flat_buffer
    • flat_static_buffer
    • multi_buffer
    • static_buffer

  • handler_ptr has been removed. Users should use net::bind_handler and/or bind_front_handler instead.

  • websocket::role_type has been removed. Users should use beast::role_type instead.

  • The following deprecated functions have been removed:

    • websocket::async_accept_ex
    • websocket::async_handshake_ex
    • websocket::accept_ex
    • websocket::handshake_ex

Programs still using these names should be refactored to use the decorator feature and the remaining handshake and accept functions.

  • The macro BOOST_BEAST_NO_DEPRECATED will no longer be noticed by Beast. The only way to enable deprecated functionality is now the macro BOOST_BEAST_ALLOW_DEPRECATED which is undefined by default. That is, all deprecated behaviour is disabled by default.

Version 295:

  • Parser body_limit is optional (API Change)
  • Fix basic_stream expires_after (API Change)
  • Fix FILE namespace qualification

API Changes:

  • The signature of basic_parser<>::body_limit(n) has changed. It now accepts an optional std::uint64_t. The caller may indicate that no body limit is required by calling body_limit(boost::none). The default limits remain in place in order to maintain 'safe by default' behaviour.

  • basic_stream::expires_after used to take a nanosecond duration type argument. This required users on systems where the steady_clock::duration_type was less accurate to explicity duration_cast when calling this function, making code non-portable. The duration type is now that of the embedded steady_clock.

Version 294:

  • Fix FILE namespace qualification
  • Fix http read bytes_transferred (API Change)

API Changes:

The following functions did not previously report the number of bytes consumed by the HTTP parser:

  • http::read
  • http::read_header
  • http::read_some
  • http::async_read
  • http::async_read_header
  • http::async_read_some

As of now, the bytes_transferred return value will indicate the number of bytes consumed by the parser when parsing an http message.

Actions Required:

  • Modify calling code which depends on the value returned from these functions.

Version 293:

  • Fix async_connect documentation
  • Fix assert in websocket
  • No automatic User-Agent in WebSocket

Behaviour Changes:

  • No automatic User-Agent in WebSocket Beast websocket streams will no longer automatically set the User-Agent HTTP header during client handshake. This header is not required by the WebSocket standard. If this field is required, user code may set it in the decorator

Version 292:

  • Fix compile errors on Visual Studio with /std:c++latest

    • static_buffer
