Has anyone gotten a straight answer about how to upgrade commerce libraries for payment module Linkpoint.

According to Linkpoint -

First of all, the update IS provided by MIVA, not Linkpoint. This is
achieved through the updating of the "commerce libraries" of the MIVA
cart and will then allow you to post via port 1129. Depending on your
carts' initial setup, this will be performed by MIVA or directly through
your host.
