Get it here.
At this point, I think all the issues that are going to be fixed in this release have been fixed so far. This beta is to get some of those fixes since the last beta out there for a little while before the final release, which should hopefully be this week. Since the last beta, there have been fixes for mobile syncing, aliases and smart journals, and improvements to the Quick Note window. Please let me know of any problems via email, the "Report a Bug" menu item in MacJournal, or the Support Forums.
