A. Introduction Schedule and Communication Calendar

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

The Introduction Schedule provides an overview of the timeline.

The Communication Calendar lists all important dates on which documents for T7 Release 11.1 will be published, including existing documents that will be revised for T7 Release 11.1.

In December 2022, 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 11.1.

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, independently of the T7 production environment. 

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 (24/7) available for a fixed price per hour and is accessible using an SSL-encrypted internet connection. The T7 Cloud Simulation will start in advance to the usual Release Simulation.
