Credit Language - USGBC and Forum - and Addenda

Does the posted credit language for the Credits, both in the USGBC's online Credit Library and here on the forum, reflect the addenda? Or is the credit language the published language and we need to track down the Addenda? Specificially, I am looking at SSc4.3 NC 2009 and the posted Addenda under option 1 states "Delete the following text, "Providing a discounted parking rate is an acceptable substitute for preferred parking for carpool or vanpool vehicles. To establish a meaningful incentive in all potential markets, the parking rate must be discounted at least 20%. The discounted rate must be available to all customers (i.e., not limited to the number of customers equal to 5% of the vehicle parking capacity), publicly posted at the entrance of the parking area, and available for a minimum of 2 years."
