This was announced at the same time as the electronic payments was ( aug. 17th- I think). You can read up on this in the ebay announcements. The easiest way i found to make this change is by using Turbo Lister. This was suggested by ebay to a power seller friend. You can upload all your listing to turbo lister & make the necessary changes. The only change there is no easy way to correct is to remove the words- money order, checks etc from the actual written listing- this has to be done one listing at a time. My friend is doing his as they come up for renewal (store) or if they dont sell. I think we have until mid- October for this change. Hope this helps!!
Good Luck!
