On Sunday, February 10, 2008 , CME Group is harmonizing the New Release environment to provide a robust customer testing environment that matches production as close a possible. This synchronization will result in identical listed instruments (for example, strike prices will match) in the New Release environment versus the production environment.

 

As a result, you can expect the following impacts to the New Release environment:

 

·         All GTC and GTD orders for futures will be removed; GTC/GTD orders for options will not be affected.

·         All UDS will be eliminated.

·         The ISIN Codes for all the currently listed products will be impacted.

o         CME Group recommends all customers purge and re-load their instrument databases from the Instrument Creation (MO (m-oh)) market data messages every week.

o         There is no impact for customers who purge and re-load weekly, or who do not rely on the ISIN Code for instrument identification.
