3. Details of the initiative

A. Introduction schedule and Communication Calendar

Please refer to the attachment for the Introduction Schedule and the Communication Calendar. 

The Communication Calendar lists all important dates on which documents for T7 Release 13.1 will be published, including existing documents that will be revised for T7 Release 13.1.

In December 2024, Frankfurter Wertpapierbörse (FWB^®, the Frankfurt Stock Exchange) will publish the detailed preliminary Release Notes listing the functional and technical enhancements that will be available in T7 Release 13.1.

Deutsche Börse will provide a dedicated release simulation environment to give Trading Participants and Independent Software Vendors (ISVs) the opportunity to perform comprehensive testing of their trading applications, independent of the T7 production. 

In addition to the T7 Release Simulation, Trading Participants can also use the T7 Cloud Simulation that allows Trading Participants and ISVs to test against the current T7 production and simulation software versions. In this environment, Trading Participants can initiate predefined market scenarios and test-specific strategies more easily than in a shared environment. The T7 Cloud Simulation is permanently available (24/7) for a fixed price per hour and is accessible using an SSL-encrypted internet connection. The T7 Cloud Simulation will start in advance of the usual Release Simulation.

For more information on the T7 Cloud Simulation, please refer to the Xetra website www.xetra.com under the following path:

B. Backwards compatibility

T7 Release 13.1 will be backwards compatible with T7 Release 13.0.
