Developer Ben Rister released Synk 5.0 on Wednesday. The new release of his synchronization and backup utility adds several new features, including intelligent synchronization that can synchronize deletions and knows if you remove a file or add one; a new preview pane that shows what will happen before you synchronize; an archive feature that stores and organizes each modified document; support for scheduled synchronizations; and more. Synk 5.0 requires Mac OS X v10.3 and costs US$20 for non-commercial use and $40 for commercial use, with free upgrades for anyone who purchased an earlier version of the software within the past year. Educational customers can get Synk 5.0 for free, and volume pricing is available for five or more copies. You can use the software free for 30 days before purchasing it.
