Deutsche Börse Group will launch Release 8.1 of the T7 trading system on 29 June 2020.
The support window for T7 Release 8.1 will take place on Saturday, 27 June 2020, between 15:00 and 17:00 CEST. Connectivity testing during the support window is strongly recommended for all participants and Multi-Member Service Providers.
The circular outlines the most important topics for the go-live preparation that should be considered for the production launch of T7 Release 8.1 as well as details about the support window.
2. Required action
With the introduction of T7 Release 8.1, all historical news messages will be removed from the system and will no longer be accessible via ETI or via GUI. Only the Eurex website www.eurexchange.com will show historical news. In order to avoid gaps or duplicate sequence numbers in the ETI news message stream and the corresponding retransmit message stream on the release introduction day, the sequence numbers of news messages will be reset to 1.
Further required actions:
Important Reminder: Please note that a change of the partition ID and/or multicast addresses resulting from the split of the Money Market futures/options and ETF futures/options will take place in the T7 Production environment two weeks after the launch of T7 Release 8.1 on 13 July 2020, as announced in Eurex Circular 027/20/Eurex Readiness Newsflash from 5 June 2020. As a result, from this date a new scenario will occur for the EMDI Market Data interface in the production environment whereby two partitions, each with their unique SenderCompID (49), will be contributing to the same multicast address. Simulation capabilities are being provided in the T7 8.1 environment.
Deutsche Börse Group will launch Release 8.1 of the T7 trading system on 29 June 2020. Please refer to the dedicated document “T7 Release 8.1 Final Release Notes” for a full overview of both the new and changed functional scope.

A. Backward compatibility
T7 Release 8.1 is a mandatory release and will provide backwards compatibility for the T7 ETI/FIX interface versions 8.0 and 8.0.1, i.e. participants who do not want to use the new functionality will still be able to connect to T7 with the interface layout version 8.0 or 8.0.1, even after production launch of T7 Release 8.1.
