This week we will be delpoying what we call - PB0901 release of HealthVault to our Pre Production Environment (PPE). We dont expect this upgrade to disrupt our partners. Next week (week of Jan 19), we will update the Production Environment with similar bits.
Once we complete the PPE release this week, we will shortly ship an updated SDK reflecting the changes. So stay tuned, we are looking forward to talk more about the release soon.
