5.6 Sun shafts disappeared?

Hello everyone, I have started using Unity recently and came in need to use volumetric light. I leaned Unity has a similar effect called Sun Shafts but apparently this effect is gone recently with 5.6 release.

All tutorials and info I find about this effect are before the new Post Processing package change, Sun Shaft was a script within the Image Effect package, but I cant seem to find this effect on Unity newest versions post processing behaviour thing; the only post I've seem about this subject, (in another forum) has no answer about this change, and nobody was able to inform how to add the Sun Shafts on Unity 5.6..

Can someone assist me?

Thanks
