# Changelog

## 1.2.1 - 2026-06-14

- Expanded the README with complete public API documentation for BBS
  configuration, lifecycle methods, callbacks, and connected-mode sessions.
- Documented all exported AX.25 and KISS helpers, constants, custom transports,
  TypeScript interfaces, defaults, validation rules, and error behavior.

## 1.2.0 - 2026-06-14

- Changed AX.25 packet logs to timestamped, single-line JSON with explicit receive/transmit direction.
- Added proactive RR acknowledgement polling when the connected-mode send window fills or a disconnect is waiting on unacknowledged data.
- Prevented a delayed poll response after REJ recovery from triggering duplicate retransmission.
- Kept poll state active when a cumulative acknowledgement arrives without the required final bit, preventing overlapping polls.
- Polls immediately after retransmission recovery, without treating a no-progress final response as another retransmission request.

## 1.1.0 - 2026-06-11

- Added serial KISS transport support through the optional `serialport` peer dependency.
- Added connected-mode send-window backpressure and buffered session input.
