You will know whether you are running the latest version of the software, because ShedTech always checks to see if there is an update available at the same time that you log in.
The version number of the software is displayed on the title bar of the starting window. If you are running an older version, you will get a message to upgrade each time the software is started. You should always download and install updates as soon as conveniently possible as some functions may become disabled as something has changed in the new version.
