I have an image from x9 that will be used for customer /staff training. Has the IDR changed since the ABA Toolbox was published? Will it change?

The visual aspects of the Substitute Check and the information content will not change. A revision to X9.90 (the ASC standard that identifies the dimensions and content) is forthcoming that increases the size of the document from 3.3 inches to 3.667 inches in order to completely fill a 8.5" x 11" page with 3 Substitute Checks. The locations and content for leagal verbiage, reconvertgn bank, truncating bank and rear endorsements stay intact.
