Changelog

All notable changes to this project are documented in this file.

The format is based on Keep a Changelog, and this project follows Semantic Versioning.

[1.2.1] - 2026-03-22

Added

  • Added optional :headers_fn connection option for dynamic websocket upgrade header refresh on each connect/reconnect attempt.
  • Added HexDocs guide for auth-header refresh and handshake-failure behavior.

Changed

  • OffBroadwayWebSocket.Client.connect_once/1 now resolves headers through :headers_fn when configured and returns typed errors for invalid callback results.
  • Handshake failures with :gun_response in both :nofin and :fin variants now stop deterministically with {:handshake_failure, {status, headers}}.

Tests

  • Added coverage for headers_fn success/error paths and :fin handshake-failure handling.

[1.2.0] - 2026-03-13

Added

  • Added :on_upgrade to send outbound websocket frames immediately after upgrade and before the connection is considered ready.
  • Added :frame_handler and :frame_handler_state for session-aware inbound websocket protocols.
  • Added reconnect-time reset of connection-local frame-handler state.
  • Added HexDocs guide structure for configuration, bootstrap hooks, frame handlers, retry/liveness, and telemetry.

Changed

  • Treat immediate on_upgrade callback failures and immediate :gun.ws_send/3 failures as bootstrap failures that follow reconnect/backoff.
  • Allow skipped inbound frames to refresh liveness when using a :frame_handler.
  • Delay connection-success telemetry and ready-state transition until bootstrap frames have been sent successfully.

Tests

  • Expanded producer and state coverage for bootstrap success/failure, frame-handler emit/skip/error paths, and reconnect state reset.

[1.1.1] - 2025-03-05

Changed

  • Released the current 1.1.x line after the signal-handling improvements from 1.1.0.

[1.1.0] - 2025-03-02

Added

  • Added a dedicated telemetry module and expanded connection telemetry coverage.
  • Added handling for missing :gun_ws signal clauses.

Changed

  • Improved connection defaults and state enforcement.
  • Refactored producer and state handling around websocket lifecycle and retry behavior.
  • Improved project documentation.

[1.0.2] - 2024-10-29

Changed

  • Released the 1.0.x line before the later signal-handling and telemetry refactor work.
