SO – I found out that the trick is to go to Downloads > Settings from the WPAdmin screen and select Migrate. You should be able to bring previous packages into the new version. I did that, but they were all missing download icons. You will have to go in and assign icons manually. The downloads did not appear immediately in posts. I think the reason for that was because they were not immediately published. Just a heads-up for those who used previous versions of the plugin….
