For your information, Morgan Schaffer has released a new version of their “Calisto Access” software.

This version is installed on all Calistos leaving the factory and we thus recommend that you download and install it on your computers.
Please keep in mind that if a computer is running an older version of Calisto Access it will not be able to communicate with a new Calisto that is running version 2.28. Thus, especially if you have or contemplate a mixture of Calisto software versions, please upgrade all computers that will be communicating with Calistos.

If you connect to a Calisto and you have the new version on your computer the upgrade will happen automatically.
