Missing get_test_result_details_for_build in TestResultsClient

Hi,
I wanted to move from 6.0.0b4 to a 7.x release but I have noticed that TestResultsClient in 7.1.0b4 does not have everything I used in 6.0.0b4 (e.g. get_test_result_details_for_build).

Do I need to use other APIs or is the wrapper incomplete?
