Synology RT6600ax: SRM Version 1.3.1-9346

Synology RT6600ax SRM Version 1.3.1-9346

SRM 1.3.1 is the current operating system of the Synology RT6600ax, RT2600ac and MR2200ac routers. Version 1.3.1-9346 RC (Release Candidate) is the second release candidate and was released today, July 21, 2022. The first release candidate was version 1.3.1-9316 RC released on June 24, 2022. Unfortunately the new 1.3.1-9346 RC version maintains the outdated PHP 5.5.25 version, an issue that I reported on June 26, 2022, almost a month ago.
