For better or worse, Sony has moved back to its regularly scheduled PlayStation 3 firmware updates, many of which have a history of including minor changes relative to their frequency.

Sony says 3.66 includes improved "system stability during use of PS3 format software and network services has been improved."
The update only took a few minutes for me to apply, before I was right back into inFamous 2, awaiting the arrival of The Beast.
