from what it seems, there is now 3.5.1 in the beta/rc and 3.6 in the main.
I think normally, all new latest updates goes first to main channel (3.6), then after some days or weeks, they port it back to the 3.5.1 beta/rc channel. I don’t think there are many new changes, there might be some stuff under the hood, like for example the linux kernel is mostly a bit more updated in the main channel, also I think there is a new bios 119. I think Valve plan to release 3.5 soon, so the point of 3.6 in main is to “differentiate” it from the normal 3.5 release, this is also why beta/rc is now 3.5.1 instead of 3.5.0, so that stable will be 3.5.0 at first, and then with time it will get updates. so the chain is 1- main branch(alpha) , 2- beta/rc , 3- stable
