I attended the Kali Dojo at Blackhat this week where I was able to look at the new version of Kali 2.0 that is coming out next Tuesday.
If you are interested in getting an early look here are instructions on how to build your own.
Here are direct links to the two ISO’s I built:
kali-linux-sana-amd64.iso
kali-linux-light-sana-amd64.iso
