MaxPresort OS Version 3.3.3.4 Released February 2022

IMPORTANT:
The USPS has added a new table to their Labeling List file. This change by the USPS has resulted in a change to our internal MaxPresort OS database structure. 
 
How does this affect you the customer?
This means the older Labeling List will not work with the new version of MaxPresort OS. Starting March 1, 2022, all customers who want to use the March version of the Labeling List will be required to use MaxPresort OS version 3.3.3.4 or greater. 
 
Effective April 1, 2022, all customers will have to update their MaxPresort OS to version 3.3.3.4 or greater to continue to be compliant with the USPS and the latest Labeling List file. 
 
For any mailings, before this date, the user will need to use their existing MaxPresort OS version.

Enhancements

This release is compatible with the new USPS Labeling List effective March 1, 2022, with a mandatory date of April 1, 2022. 

Corrections

This release fixes an invalid character in position 732 of the header record for Mail.dat File Format 22-1.

This release fixes Letter Mailings with Postcard Piece dimensions. Originally MaxPresort OS was grouping these mailing instead of bundling them. This now functions as expected.
