A new firmware update is rolling out to the Aeotec hub and the V2 and V3 SmartThings hubs which includes support for additional matter 1.2 features.
(Note that that is not matter 1.3. The matter specification itself is updated twice a year, but it can take platforms a while to get around to implementing it.)
