This is freaking amazing. Opera was the fastest most optimized browser I ever used. Started with 6, finally broke down and switched to Vivaldi after 1/4 of the web stopped working on 12.16 due to ECDHE :(
Now the more interesting question is, How was it leaked, were Opera Hacked?
I really wish Presto could be open sourced, it is small and nimble, and should fit well for those using Web Technologies as Desktop Apps. And if it Presto refocus on that, they can finally throw away all the IE quirks mode.
You can still find it, I just successfully built it for Linux this morning. People already have it running on Raspberry Pis, a platform Opera never supported.
