It has been quite the day for Universal applications! Now Up to Date and Contact 5.3 brings this venerable contact management software into the Intel Mac age. That isn't the only change that you'll find in Up to Date 5.3 though. Attachments can now have long filenames, fixed several scripts, and several other bug fixes.
Now Up to Date and Contact costs $170 for the whole shebang (manual and maintenance) though there are several tiers available.
