Overview

• The Connectivity Standards Alliance published Matter 1.4.2 on August 11 as a maintenance release focused on stability, interoperability and onboarding simplification.
• Wi-Fi-only commissioning via Unsynchronized Service Discovery removes the mandatory Bluetooth LE requirement for device setup.
• New network-management rules set minimum router support for 150 Thread and 100 Wi-Fi devices while optimizing traffic with quieter reporting and Target Wake Time.
• Security enhancements include Vendor ID verification, certificate revocation lists, access restriction lists for routers and device ID revocation to guard against counterfeits.
• No Matter-certified Wi-Fi routers are yet on the market, so real-world impact relies on platform and device makers rolling out firmware updates or launching Matter-enabled hardware aided by CSA fast-track programs.
