USPS appears to have rolled back some of their recent API/shipping method changes so we will be releasing updates for USPS Advanced 4 and 5 over the next few days. The primary issues are with First Class domestic and international methods. All other methods appear to be working fine.

As mentioned previously, USPS International will not be updated as it is not tenable for it to support the updated USPS API. Support for USPS Domestic and USPS International ceased several months ago however both modules will work to a certain extent. It is up to the user to decide whether to keep using those modules but no further updates will be made to address any issues with them.
