The more things change the more they are the same

Hi
I have a question about this quote by Alphonse Karr.
"The more things change the more they are the same"
I want to know what this really mean about change?
If you know what it really means could you please give me some explanation whats really saying about change.

thanks

It's more to do with life than either changing or not changing. We think life's all about change, but this phrase is said when things do not.
