To simplify the iLink session behavior, effective Sunday, January 6, 2019 (trade date Monday, January 7). All Convenience Gateway (CGW) iLink sessions will move to MSGW-style Session Connection and Resend Request. The following CGW features will as a result match the MSGW current state.
†Please note that certification is required for all CGW customer systems via AutoCert+ by end of day Friday, January 4, 2019 for continued access to the production environment. Customer systems that trigger port closures due to resend requests or other issues will not be allowed to reopen ports and access the market until certification is complete.

CME Group is implementing end-to-end technology changes to support increased price granularity. Currently, CME Group systems support a maximum of 7 decimals. With this initiative, products with up to 9 decimals may be listed and traded. On Sunday, January 13, 2019 (trade date Monday, January 14), pending regulatory approval, the 2-Year Treasury Note futures, all 2-Year Treasury Future Spreads (including Calendar Spreads, Tail Spreads and Inter-Commodity Spreads with a 2-Year Treasury Future) along with the futures portion of covered options UDS, will move from 7 decimals to 8 to support trading at 1/8 of 1/32.
A production test instrument for the 2-Year Treasury Note futures is currently available on CME Globex to give customers the ability to confirm system readiness for the introduction of 8-digit decimal price precision. Upon the launch of this test instrument, clients whose systems are not yet prepared to handle 8 decimal precision must ensure their systems have the ability to ignore market data and iLink/Drop Copy execution reports on this new instrument.
Customers are encouraged to move to support 9 decimals now; but there are no plans to list a product that uses the 9th decimal at this time.
With this release, customer certification will be required for MDP 3.0 and Streamlined SBE. The new Market Data templates are currently available in New Release and the AutoCert+ test suite is now available for certification.
