SOPC Builder clock domain crossing

Before jumping the gun: What version of Quartus/SOPC Builder? The final release 4.2 version?? pre-release & beta versions did not support the clock-domain crossing feature as noted in the readmes/release notes.

The final release, which came out of engineering's hands barely a week ago (build 157, I believe), suppors the clock-crossing feature.

By the way this is one of the most powerful performance features to be introduced in some time for our tools. Being able to put custom-logic or a tri-state bridge with many masters (things that slow clock speeds down) onto their own domain lets one easily achieve max performance out of the CPU and other peripherals.
