Is this the Latest Raspberry Pi iteration?

I am trying to recover my Insteon devices etc and heard there is a more recent version. It is not clear how to update my current Raspberry Pi install, so I thought I would just make a new install on another miniSD.

7.6 is the latest stable version of Home Assistant OS. You don’t need to create a new install to update.

Go to the Supervisor System page and you can update the OS there.
