The Connectivity Standards Alliance (CSA), the keeper of the Matter smart-home protocol, softly released new matter update version 1.4.2 on August 11, 2025. Expected yet significant release meant not to wow with spectacular features but rather to strengthen the fundamental architecture of modern smart homes.
Central to this new matter update is Wi-Fi-only commissioning, which enables devices to connect to the network utilizing just Wi-Fi via Unsynchronized Service Discovery (USD), hence removing the need for required Bluetooth LE audio
Security has undergone a notable improvement. The new matter update adds Vendor ID verification to guarantee that ecosystem managers are real; Access Restriction Lists (ARLs), which limit sensitive router configurations; and Certificate Revocation Lists (CRLs), which help ecosystems to identify and block compromised or fake devices.
With new matter update, Matter now supports scenes with time-based triggers; includes better, quieter reporting to reduce needless data transmission and extend battery life; and provides standardized node reconfiguration and distinctive endpoint identification to help avoid duplicate devices and enable firmware-driven updates to improve user experience.
Standards controlling robotic vacuum actions have also been improved: commands now work predictably across several ecosystems, eliminating the need to manually cancel chores before beginning new procedures. Moreover, in addition to low-power features like Target Wake Time, new infrastructure benchmarks call for routers to handle at least 150 Thread devices and 100 Wi-Fi connections.
These fundamental improvements with the new matter update hold the promise of a more dependable, secure, and coherent smart-home experience. Their success, though, depends on quick acceptance by platform providers and device manufacturers, a problem Matter has historically had. Fast-track initiatives designed to speed up integration and certification are helping the CSA to solve this problem. If Matter 1.4.2
