I'm planning for some upcoming DL3 work and I haven't used them since the V2 release.
Looking in the current version of HOG I see,
DL-3 Global, Graphic and Motion libraries
DL v2 Global, Graphic and Motion libraries
Are the "DL-3" libraries for V1 on the DL3, and "DL v2" libraries for V2 on the DL3?
