View Epix 2 Software Update List?

Hi Folks - I'll get my Epix this morning.  (Scored with a coupon for 20% off retail AND my company is reimbursing me for the whole cost!.  I love my job!)  

I hear many (all?) of the Epix 2 watches come with a very old software 6.20 version loaded when the watch was made a few weeks ago.  Now there is a 7.20 update?  Where can I see a list of what was changed/fixed/added?  I've been searching forever to find this.  All the older watches (e.g. 745) you can see a rolling list of updates and what was done with each version since it was originally released.

Thanks!
