Hey John,
Apologies for any confusion that post might have caused – can you link to where you found us recommending version 3.9.2? We can fix that up immediately.
As for what to use now, in general always use the latest version available. As of right now, this will be 3.10, however a brand new update, 3.11, should be arriving sometime very soon – hopefully this week! 🙂
So when that version comes out, upgrade to that, and so on.
I hope this helps – let us know if you have any followup questions here, comments, concerns, etc.
Cheers!
George
