Snow Leopard is on the Prowl! The Cat is out of the bag! More tortured cat metaphors!
Yes, Snow Leopard is out and so is MacJournal 5.1.4. If you use the former, you'll want the latter as well. There was only one cosmetic issue that I found in 5.1.3 (as well as a rare crash), but that is fixed in 5.1.4, along with some other things. It's a benefit to all three OSes on which it is supported. Download it at Mariner now or get it from the Check For Updates in a previous version of 5.x.
