This is the fifth beta of MacJournal 5.0.3. There are more fixes to be had, as expected. There are fixes for the smart journal configuration, LiveJournal blogging, SFTP uploading, image uploading in general, and image resizing. Documents open at quit will now be restored when you launch again. And there's some more, smaller things as well. Happy March.
