     32. Added Array `poseNetOutput` to Datum so that user can introduce his custom network output.
     33. OpenPose will never provoke a core dumped or crash. Exceptions in threads (`errorWorker()` instead of `error()`) lead to stopping the threads and reporting the error from the main thread, while exceptions in destructors (`errorDestructor()` instead of `error()`) are reported with std::cerr but not thrown as std::exceptions.
     34. When reading a directory of images, they will be sorted in natural order (rather than regular sort).
+    35. Upgraded OpenCV version for Windows from 3.1 to 4.0.1, which provides stable 30 FPS for webcams (vs. 10 FPS that OpenCV 3.1 provides by default on Windows).
 2. Functions or parameters renamed:
     1. By default, python example `tutorial_developer/python_2_pose_from_heatmaps.py` was using 2 scales starting at -1x736, changed to 1 scale at -1x368.
     2. WrapperStructPose default parameters changed to match those of the OpenPose demo binary.
