+- The `newmodels_engine` resource no longer exists, all exports are in `newmodels_red`
+- Remove all `setElementData` and `getElementData` calls related to newmodels
+- Functions `getDataNameFromType` and `getBaseModelDataName` no longer exist since we don't use element data anymore
+- Functions like `isDefaultID` still exist (exported)
+- Other useful functions were renamed
+- Replace `sampobj_reloaded` with `sampobj_red`
+- Use the new exported functions or use the loadstring method
+- Exported functions to add/remove new models have been rewritten, see the documentation for more details
+- See the `test_vehicles` resource for example usage
