Houdini 19.0.503 Updated the USD library with a couple of non-standard methods on the HdSceneDelegate and UsdImagingPrimAdapter classes. This will only affect users that build their own Hydra plugins. And in particular the only code change that might be required would be to implement the GetScenePrimPaths API on any instancer-type UsdImaging prim adapters. A simple implementation can be found on UsdImagingPointInstancerAdapter. See the changes on github at:
