USPS sent out an email at end of Dec 2012 indicating there would be a number of updates to their API from 27th Jan 2013. WebShopApps have assessed these changes and are providing the community with a patch to ensure you are able to move to the new API.
The update to the rate calculation includes price changes and new shipping methods. The largest changes are:
- Parcel Post is to be replaced by Standard Post
- First Class Mail International Parcel replaced by First Class Package International Service
If your Magento installation is not updated you will be unable to see these new services, and the old services will obviously disappear.
Our patch release is available via our website and is free of charge. This has been qualified on Community Edition only Magento versions 184.108.40.206 to 220.127.116.11.
This extension is free and unsupported. If you require advice or assistance then we encourage you to purchase a support package.
If you are running Enterprise Edition then we recommend you download the official Magento patch in your downloads area on Magento.
If you are running the WebShopApps Dimensional Shipping extension please contact us for an update to this.
