MacJournal 3.0 has come out over at <http://marinersoftware.com/>! Sorry about the lack of announcement here; the past week has been very very hectic for me. I'm way behind on my e-mail too, so apologies to anyone that has e-mailed me in the past few weeks. I will get back to everyone eventually, I promise!
I'm going to post a beta of 3.0.1 tonight as localizations are updated. We've already got one back and I'm expecting a few more very soon. In the meantime there are a few bug fixes in the beta.
