Hi,
There aren't too many product updates that get sent out, once every few months it seems. There are two places I can think of that you might get what you want:
-Click View Logs on the left
-Beside Client Management click View Logs > System Logs...
-New engines and what not show the version loaded in there
You can also get info by doing the following:
-Click Help & Support in the top right
-Click Troubleshooting
-Select Versions on the left
Here you can see at least the versions of each component, I am not so sure we will log any data in any other accessible location.
