Original Message: 07/11/19

M7 version 6.8 is expected to go live in December 2019. The current scheduled release date is 10th December 2019, pending successful testing.

Release Description:

  • Webstart Comtrader will be discontinued
  • New mandatory standalone Comtrader v6.8
  • Self-trade labelling – anonymous message issued to members when self-trade submitted

SEMOpx would like to take this opportunity to advise members that as Webstart Comtrader is expected to be discontinued, it is recommended that members install the standalone Comtrader. Members can go ahead and install the standalone Comtrader version 6.7 now, enabling members to already address IT requirements for same, and thus enable potentially a more straightforward implementation of Comtrader version 6.8  

Although member testing is not mandatory for SEMOpx members for M7 version 6.8, members using the Advanced Simulation (ASIM) environment should note the following information:
  • In order to prepare ASIM for the test phase an outage was taken on 05/11/2019 between 13:00 GMT - 14:00 GMT. 
  • M7 6.8 has been available in ASIM since 05/11/2019 and is officially open for testing as of next week.
  • The official member test phase in the ASIM environment is planned to start on Tuesday, 12/11/2019
  • Subject to successful internal testing, Go Live in Production environment is planned for Tuesday 10/12/2019
