Core is a web-based, cloud software solution and so you are always going to be on the latest version. We do the software updates automatically in the background on a regular basis and notify you about it when you log in to the application. You are also provided a link to the release notes or web logs about the features added and improvements made. If you want, you can dismiss the notification so that it does not appear again.
