These modifications are:

  * removal of 1 duplicate image (patches_105.jpg, pixel-identical to
    patches_101.jpg),
  * removal of 3 duplicated bounding boxes (one box listed twice verbatim in
    each of crazing_120, inclusion_62, patches_198),
  * addition of a seeded, class-stratified train/val/test split,
  * conversion of the annotations to YOLO format alongside the original
    Pascal VOC format,
  * regeneration of classes.txt, data.yaml, ImageSets/ and this documentation.

commercially, provided you give appropriate credit.
