+**Images sort by position patient**
+
+The ImageSet sort has been modified: images are now sorted by ImagePositionPatient by default. If ImagePositionPatient is not available, the sort will fall back to InstanceNumber.
+
+**To revert to the previous sorting method, you can add the customization instanceSortingCriteria as shown below:**
+
+```
