[CentOS] /lib/firmware/microcode.dat update on CentOS 6

Dear All,

An update just brought on my CenOS 6 boxes updated microcode.dat files:

  /lib/firmware/microcode.dat

Does anybody know off hand what (how critical) is that, as, if it is 
related to most famous these days trouble with CPU hardware, I will need 
to reboot relevant boxes to have new microcode loaded. But if it is not 
that critical, it can wait till next reboot.

Thanks a lot and apologies for laziness (not looking into details of 
this particular update myself).

Valeri
