Impact Assessment

All trading members across CM, FO, CD, and CO segments who use NEAT Adapter are impacted. The upgrade is mandatory and introduces stronger security through new encryption and authentication. Members should plan the installation before older versions are discontinued to avoid trading disruptions. GR ports remain segment-specific (CD: 10877, CO: 10857, CM: 10817, FO: 10827) during the coexistence period.

Impact Justification

Mandatory software upgrade for all trading members across four segments; non-compliance may disrupt trading access after discontinuation of older versions.
