The API above was added in astools 2.4.101.   API Tools does not allow 3-segment since tags.I was forced to select 2.4 as the since tag. 

Master then moved up to 2.5.  The Since tags were required to be updated, since comparisons to a 2.4 installation showed the APIs were not there in 2.4.0.

I then switched astools to 3.0.0.  APITools then complained that the since tags were innacurate. A 2.5.0 release never existed anywhere as a build. And 2.4.0 did not have the APIs.
