"Because Article 83 supplements Article 82, its forerunners were each slightly amended and extended to reflect the changes made to the forerunners to Article 81 and Article 82. The words 'or to require the seller to deliver substitute goods' were therefore also inserted in Article 83." Other changes are "retains all other remedies" rather than "shall retain all the other rights conferred on him by the present law"; and the addition of the words "under the contract and this Convention".
