+# Changelog
+
+## 0.1.0
+
+- Initial release with a pure Dart continuous-phase BFSK encoder.
+- Add incremental Goertzel decoder, framing, CRC-32, and streaming APIs.
+- Add audible 1200-baud and near-ultrasonic BFSK presets.
+- Make the 1200-baud V.23 tone pair the phone-oriented default and retain the
+  original channel as `Bfsk.poorQuality()` (`Bfsk.robust()` remains an alias).
+- Add the CRC-protected READY control frame, padded and repeating encoders,
+  duplicate-aware streaming detection, and a pure-Dart wait-state helper.
