La 2.0 no está todavía disponible, aunque ya hay changelog:
SiyahKernel v2.0 - not released yet
Unified kernel for both Samsung and CyanogenMod Roms...
Some stability improvements
Auto-rooting removed. If you are using stock, flash this kernel and download su package from http://goo-inside.me/superuser , reboot into recovery and flash it. Is it hard? no, it is not! if you can use odin, you can do this as well.
Lo que no me queda claro es que parece que va a quitar el auto-rooteo...
