Please do not say such a thing in a public forum where someone innocently may not know better. Slysoft updates AnyDVD on a pretty consistent clip, however the releases are meant to respond to specific situations or issues that users are having. If you (in general) are not having that issue, it's not advised to upgrade unless there is some new feature that the new version offers. You basically replace the stable version that's been working well on your system for one that may or may not have as yet undiscovered bugs.
That's why many businesses are still using Windows XP and Internet Explorer 7. They aren't going to blow up a stable environment that their developers use on a daily basis just to get the latest bell or whistle. Don't get me wrong, i understand the sentiment. I felt the same way for a long time, however being a software developer for the last 10 years has taught me that having the latest and greatest is not always the best thing. It's become one of my pet peeves now so much so that I detect which browsers my users are using at the company that i work at and warn them that the internet app they are using has not been tested on their version of IE when they just decide, against corporate standards mind you, to upgrade to IE 10.
