-* **Change to Magento Admin to support recent USPS shipping changes**. On February 23, 2018, USPS  removed APIs that support the creation of shipping labels without postage. In response, we’ve removed this functionality from the Magento Admin. Consequently, you cannot create and print shipping labels that do not have postage applied. If you require USPS postage printing capabilities, please visit [Magento Shipping](https://magento.com/products/shipping) to learn more, and explore various shipping extensions on Magento Marketplace.
