Just create Quick Smoke, hit render. It does not render Alpha like before anymore ...

I could not find a real difference between 2.65 and 2.67.
Make sure to switch from "Sky" to "Transparent" in the Shading panel (Alpha setting). The Alpha pipeline changed in Blender 2.66.

@Thomas
That fixes the "issue" I am having with Smoke and Fire alpha.
I really did not know about this Alpha pipeline change and this is actually really important.
I bet many people are asking the same questions. I should add it into my BLOG and NOTES.
Thanks a lot Thomas, this is very helpful.
Ok, I updated it in my blog. Personally I think the default of Alpha should be "Transparent", and not "Sky".
Or maybe add a little snippet that tell user to make sure to change Alpha to Transparent somewhere that user can easily see.
