Changes, a beautiful application that allows you to easily compare directories and files, was released today. I got into the Changes beta late in the game, and I don’t know how I got anything done without it. It makes comparing text files ridiculously easy and, dare I say it, fun. The developer is extremely responsive, too, and has a great first name to boot.

Changes has a 15-day free trial, and is available for $39.95. Additionally, you can get $10 off the asking price if you act soon by using TUAW’s coupon. I strongly recommend that anyone who works with plain text files download Changes and give it a try. It’s a must-have utility.
