[0.8.9] - 2026-10-23

Fixed

  • Retain pending asynchronous heartbeat encodings so scheduled heartbeat frames reach the transport and keep idle channel connections alive (#111).

[0.8.8] - 2026-10-20

Added

  • Expose connection_info/1 with a unique attempt reference, current status, and retained error independently of telemetry configuration. HTTP 401/403 upgrade rejections remain distinct from transient refusal and timeout (#110).

Fixed

  • Reject duplicate channel topic registration with the existing PID, retaining one usable channel and avoiding duplicate wire joins. Safe registration failures preserve initialization privacy (#109).
  • Cancel pending auto-connect and retry timers on explicit disconnect; ignore stale timer and transport events. Duplicate connection notifications no longer restart heartbeat timers, and successful attempts clear prior errors (#110).
  • Honor the documented :reconnect? option, with :reconnect taking precedence when both are supplied (#110).

[0.8.7] - 2026-10-19

Fixed

  • Keep private callback arguments and queued messages out of OTP crash reports, including initialization, cleanup, and asynchronous message-worker failures. Failures use the safe exit reason :private_callback_failure, preserving transient channel restarts and explicit leave behavior (#108).
  • Keep private startup options and channel parameters out of supervisor status, startup, and restart reports using separate configuration storage. Supervised storage follows the supervising parent's lifetime; direct-start storage closes with the client. Release unused specifications with discard_child_spec/1.
  • Verify published transport status, crash reports, and private reply delivery against the upstream diagnostic fix.

Changed

  • Require http_web_socket 0.21.14 or later in the 0.21 series, consuming the published fix for http_fetch #136.

[0.8.6] - 2026-10-19

Fixed

  • Restore active channels after transport reconnect, preserving join params, custom channel callbacks, and the original message recipient. Channels left explicitly stay left.
  • Omit private message content, transport options, and exception details from telemetry before dispatching to handlers.
  • Redact private state, current messages, and callback-provided termination fields in client status callbacks.
  • Use the numeric release tag when running published-package E2E checks.

Changed

  • Support http_web_socket 0.20.x and 0.21.x, locking development to 0.21.13.

Known Issues

  • Full private RPC confidentiality remains blocked by OTP crash reports retaining original exception arguments and private state exposure in the underlying transport: #108, http_fetch #136.
