PHP 5.2 is out

I don't usually blog much... and certainly not about things like releases of new PHP versions. However, I think it's worth noting that php 5.2 has been released. From the sounds of things, and certainly from my minimal experiments with it, it seems that php 5 may have finally arrived.

Anyone out there running php5 in heavy (large scale) production? Is it time to move beyond the safe "known entity" comforts of php4?
