Hi Ravi,
There will certainly be new functions for auth. objects/fields belonging to GRC 10/10.1 box itself.
The other components: ECC , BI , etc. have remained the same. So, there will be not any new auth. objects/ fields introduced through GRC 10, for these components. They will be incldued , if you uograde any of these components, and do Rep. sync.
