B1 was re-recorded for Office 2019/365, B2 hasn't been yet but nothing much has changed since 2010 so it should look very similar and most/if not all will work the same.

I'm currently in the process of re-recording Beginner 2. The old version should work just fine. I explain the major differences in versions in B1 (Memo fields are now called Long Text, stuff like that). See this page for details. When B2 is ready, everyone who has the old version will get a free copy.
