This seems to be the following change (from CHANGES)

a. Using address@hidden or ${a[*]} with an array without any assigned elements when the nounset option is enabled no longer throws an unbound variable error.

This mirrors the behavior of address@hidden

If I set bash to complain about uninitialized variables

 echo ${undefvar}   
bash: undefvar: unbound variable     # -u is still in effect
