                      This defect fix addresses an issue where mode switch did not succeed when first attempted after system startup.

                      Important: As part of this fix, we have created the MODE_SWITCH_ARBITRATION_CACHE_WAIT_TIME_MS configuration setting within the RealTime_ModeSwitch.json file. This setting enables you to modify the Mode Switch arbitration cache wait timeout. The default wait timeout is sufficient for small- to large-system deployments.

                      For more information, refer to "Modify the mode switch wait timeout" in volume 1 of the AVEVA Enterprise SCADA RealTime Administrator documentation.

                      Important: To support custom-defined icons, we have modified the GetIcon function included in the following displays:
                      - SUM_ANALOG
                      - SUM_DEVICE
                      - SUM_FLOWTOTAL
                      - SUM_RATE
                      - SUM_REGION
                      - SUM_SITE
                      - SUM_STATION

                      If you have customized versions of these displays, you must manually migrate the modification of the GetIcon method to your displays.
