We have updated our licensing version for Sage 300 Subscription customers. In the License Manager you will now see Version 8.8 for most modules and 7.3 for Payroll. This simplifies your upgrade process by not having to update your Subscription licenses for every new release.
You can find out what version of Sage 300 you are using from the Help menu. Choose About Sage 300, and then click on System Info.
