I choose not to "auto update" version 2 users because many people wish to continue using Beersmith2 and also BeerSmith 3 is a paid update.
I will be sending emails to the email list shortly announcing the release of BeerSmith 3, and may also post an update to BeerSmith 2 with some minor fixes and an announcement about BeerSmith 3 so people know the new version is out.
