Yes, you are right, they changed this bit of their library. When you say 
wou weren't able, do you
mean that you haven't had the chance yet or that you had problems? In 
principle,

adobe::any_iterator<T,std::bidirectional_iterator_tag>

is the same as

adobe::bidirectional_iter<T>

so the migration to the new interface should be straightforward.
