 ## Update Notes
 * If you have previously had chasemapper or auto_rx installed, you may need to update flask-socketio to the most recent version. You can do this by running `sudo pip3 install -U flask-socketio`
 * As of mid-April, there have been additions to the chasemapper configuration file format to enable interfacing with the new [v2 Sondehub Tracker](https://v2.sondehub.org/), including a selection for the online tracker in use. You will need to update your configuration files for chasemapper to continue working. Integration with Sondehub v2 is still in progress.
+* Further updates to interface with SondeHub's payload recovery reporting system have been introduced in early June (v1.3.0).
 
 ## Docker Install
 The fastest way to get chasemapper up and running is to use the pre-built docker container. Information on using this is available here: https://github.com/projecthorus/chasemapper/wiki/Docker
