+* Wed May 13 2020 Richard Shaw <hobbes1069@gmail.com> - 0.2-2
+- Update per reviewer comments.
+- Renamed package to lpcnetfreedv (same as library), repo will be renamed in
+  the near future.
+- Made library private as it is essentially a plugin for freedv.
+
+* Mon Apr 20 2020 Richard Shaw <hobbes1069@gmail.com> - 0.2-1
+- Initial packaging.
