Changelog

All notable changes to this project will be documented in this file.

[0.7.1] - 2025-07-13

Changed

  • Hardened and fixed regression in CircularBuffer when buffer full

[0.7] - 2025-07-12

Removed

  • Full circle: Remove explicit cancellation token parameters introduced in 0.6
    • Parameter removed from WebSocketClientAsync, BufferedSocketAsync, ISocketAsync, HasSocketOperationsAsync, AsioSocket
    • Built-in default cancellation of couroutines sufficient, see updated example in examples/asio/ex_cancel_asio.cpp

[0.6] - 2025-07-07

Added

  • Made async read/write operations cancellable by introducting a "cancellation slot" parameter
  • Cancellation support implemented in WebSocketClientAsync, BufferedSocketAsync, ISocketAsync, HasSocketOperationsAsync, AsioSocket
  • New error code WSErrorCode::operation_cancelled = 11
  • ASIO cancellation example in examples/asio/ex_cancel_asio.cpp

[0.5] - 2025-06-20

Changed

  • Refactored OpenSslContext, changed SSL security defaults

[0.4] - 2025-06-20

Added

  • New method std::expected<bool, WSError> can_read() in WebSocketClientAsync, ISocketAsync, BufferedSocketAsync, and AsioSocket

Changed

  • Removed all usings of std types within ws_client namespace, now fully qualified use everywhere
  • Improved error handling and messages for SSL and sys calls
    • SSL error queue always cleared before SSL calls

Fixed

  • Error in macro WS_ERROR if used outside of ws_client namespace due to unqualified use of WSError and WSErrorCode if no using namespace ws_client at call site was present
  • Fix examples/tests where ASIO SSL hostname verification fails by adding call to SSL_set_tlsext_host_name

[0.3] - 2024-10-13

Added

  • This changelog file
  • New Makefile with commands autobahn-docker, dev-install, test-close

Changed

  • During tear-down of websocket client, skip SSL and TCP shutdown (directly close) if websocket client is in faulty state. This is to prevent the client from hanging/reaching timeout, and is closer to the behaviour the RFC spec mandates.
  • Added parameter bool fail_connection to socket API close and shutdown methods. The parameter should be set to true if the client and/or connection is in a faulty state. On shutdown/close, the client will skip SSL and TCP shutdown and directly close the connection since it's likely that the peer will not respond.
  • Removed dev_install.sh script (moved to Makefile)
  • Better error message printing in examples
  • Log alert close_notify in OpenSslSocket as warning instead of error

Fixed

  • to_string for ws_client::close_code also maps not_set
