    Hello @Connex_Ananth,

    What version are you on at the moment? The GR at this time is but the firmware version has an additional vulnerability fix, so I would suggest going with that.

    To be honest, there have been a lot of other maintenance releases and new features have been introduced on each branch of 6.5.x

    I would suggest looking at the release notes for all details like fixes, known issues etc on that specific version.

    Hello @shiprasahu93

    Thanks for your reply, this is new deployment and we would need to inform them the quite best stable firmware with new features and low bugs.

    If they are not using Dell X series switches or Android Mobile Connect clients, I would suggest going with This has all the latest features and fixes from older firmware versions.

    Otherwise, it would be best to stay on and wait for the next General release firmware.
