The USPS module is using a retired API and costumers can't check out

[Orion Vianna]

Hi,

USPS retired the shipping rate API which caused Satchmo to stop
processing orders. The API was retired on September 28 and there is a
transition guide to the new version at
https://www.usps.com/business/web-tools-apis/2014-rate-webtools-v3-v4-transition-guide.rtf

This is only a problem when the USPS module is used.

Is there a patch available for this? Have anyone solved this issue?

Thank you.
