Shipping label generation was failing on me when trying to ship today's orders. According to the error messages coming back, two fields that were previously optional are apparently now required. Double checking against the API docs, these are not labeled as required for USPS. So that's a little annoying. Thankfully, I can edit database records to put in the required information and update the server side code to make sure the data gets there for future orders, but it's late and I want to go home
