Hi Pilou, you mean when did they start developing them?

I think they've been working on different parts of it for the last 10 years or so. So some parts are something like 5 months old and some parts are 10 years old, and various things range in between that.

If you want more information on their library, you could try contacting them, this is their web site: http://integrityware.com/
