Hot on the heels of the new Palm Desktop 4.0 (see "Palm Desktop 4.0 Released" in TidBITS 622), Power On Software has released Now Up-to-Date & Contact 4.2 for Mac OS X, which adds Palm synchronization capabilities back to the popular calendar and contact manager. Also new is a backup utility that lets users undo synchronization sessions, the free NowPak for iPod module that makes it possible to load contacts from Now Contact into an iPod, and a new holiday file that adds many European holidays. If you don’t have a Palm OS handheld and don’t need the new European holidays file, there’s no reason to download this upgrade. Plus, only Mac OS X users need even consider the upgrade – Now Up-to-Date & Contact 4.0.3 remains the current version for users of Mac OS 8.6 through 9.2.2. Now Up-to-Date & Contact 4.2 is a free upgrade for owners of version 4.0 or later; upgrades from earlier versions cost $50, and new copies cost $120. A trial version is available as a 15.2 MB download.
