 - requestNewAuthToken will clear the token if it fails.
 - request auth token on every retry, not just after 403
 - update to use nopoll v 1.0.2
+- Add pause/resume heartBeatTimer
+- parodus event handler to listen to interface_down and interface_up event
+- Pause connection retry during interface_down event
+- Add callback handler for ping status change event
+- Fixed nopoll_conn_unref crash
+- Update retry timestamp in connection-health-file
+- fix so that parodus can be killed, even if in a connection fail loop
+- provide signal handlers so we shut down properly when INCLUDE_BREAKPAD active
+- send status code and reason in websocket close message
+- dont try to install handler for signal 9 
 
 ## [1.0.2] - 2019-02-08
 - Refactored connection.c and updated corresponding unit tests
