The ASUS GT-BE98 Pro, RT-AX86U_Pro and a few others ASUS models have had this new release available to them an so far no real issues around AiMesh stability has been reported.
I appreciate early days and changelog reads more around Security improvements (certs, buffer handling and data processing workflows) etc.
FWIW, I did hear that malware was effecting certain ASUS routers, hence these quick Firmware releases.
Always nice to have a volunteer to try first
