What about this? Not as pretty but explicit.

orig_dict = {'a' : 1, 'b' : 2}
new_dict = {'a' : 2, 'v' : 'hello', 'b' : 2}

updates = {}
for k2, v2 in new_dict.items():
    if k2 in orig_dict:    
        if v2 != orig_dict[k2]:
            updates.update({k2 : v2})
    else:
        updates.update({k2 : v2})

#test it
#value of 'a' was changed
#'v' is a completely new entry
assert all(k in updates for k in ['a', 'v'])
