Has there just been a couple of big updates?

Hi.

 

I have NAV Gaming Edition and just got back to my PC there to notice a solid 50% CPU usage from NAV in Process Explorer that had been running for some time.  I checked NAV gui and saw there was an update 9 minutes previously.  A couple of minutes later the CPU usage dropped to 10-15% then wnt back to 50% for a few more minutes this time the updatesdefinition said 2 minutes ago and I've just checked again and it's saying definition updates 27 seconds ago!

 

 The CPU usage has settled down to the normal amount for the system, 1-2%, but the question really is, were there two or three updates just now, big one's?

 

Also, is there a page here that lists updates history so I just check myself next time?

 

Thanks.
