New Functionality  

Instrument Creation (MO) Message Enhancements  
Effective this Sunday, July 29, 2007, CME Group is launching the following enhancements to the Instrument Creation (MO (m-oh)) RLC market data message in the New Release environment.

These new fields are scheduled to launch in the production environment in Q1 2008.

Complete specifications for the MO market data message is available in the Market Data Platform RLC Message Specifications.

Product listings and ISIN codes, as found in the CME Globex Internal ID field of the MO message, may be different in each environment. CME Group recommends that customers use the Market Data Platform channels specific to each environment, as defined in the channel definitions:

• Production Channel Definitions

FIX/FAST Launch in New Release Environment  
Effective Monday, August 13, 2007, in the New Release environment, CME Group is launching the new FIX/FAST market data format for customer testing.

FIX provides the core message structure and syntax while the FAST protocol increases optimization. FIX/FAST is the basis of a new industry standard for market data.

The FIX/FAST Software Development Kit, including Market Data Platform channel definitions and reference code, is available online at www.cme.com/fixfast. Please note: the TCP replay functionality will not be available in New Release with this launch. The TCP replay functionality launch will be announced in a later CME Globex Notice.
