    • 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.

CME Group is the world’s leading derivatives marketplace. The company is comprised of four Designated Contract Markets (DCMs).
