Marketpress - When will you have the USPS September Shipping API Update implemented?

USPS updated their API this week and Marketpress hasn't been updated since July, so it appears it has not been updated for the API changes. My First-Class Parcel products that are under 4oz are no longer being tagged with correct postage. A 0.96oz product cannot fit in a bubble mailer (we don't have bubble mailers setup as an option) and shipping is getting priced at $0.49 - $0.70, where it should be closer to $2.00 (usually around $1.93).

I see that other eCommerce solutions have released updates for the September API updates. Please help ASAP! We have had to disable First-Class Parcel as an option and this could cost us business.
