This patch requires v2.06 to be installed, and fixes errors in the method 'rmintsig', where poor program flow resulted in non existenet constanats being referenced, and incorrect shipping costs tables being installed. A new shipping method Royal Mail Airmail 'rmairmail' has been added, which enables the standard RM Airmail service.

Installation of this patch involves copying these files over the v2.06 ones to complete the update to your installation.
