Documentation out of date.
The SDP release 2019.3.26571 (change 26574) includes assorted files in the 'doc' folder, most of which are out-of-date or don't follow any standard numbering. Most importantly, the 'primary' doc is the SDP Guide, and this is still marked as 'r18.2', and as this doesn't reference more recent changes in the SDP functionality (nor many of the scripts) it is difficult to trust that this, or the other docs are relevant for the SDP with which they're packaged.
