USPS shipping API changed/removed First-Class Parcel?

Has anybody noticed that their USPS shipping options with the default USPS shipping extension at checkout no longer include "First-Class Parcel?" I believe that something changed in the API, possibly to "package service?"

Just had the same problem. USPS just updated their term for First Class.

go to catalog/model/shipping/usps.php

Update the following:
old term: 'First-Class Mail Parcel'
new term: 'First-Class Package Service - Retail'

Has this recently changed again? I've made the file edit but no luck. Brand new installation...

Sal C.
