Where to get the 5.x edge server for linux?

[ptc-6243350]

The downloads section does not appear in my view of the community site. Also, in reading the community documentation on the edge server, there is mention made of something called "channels" and an "AlwaysOn" service. I can find neither in my 5.0 thingworx, have they gone away?

Our upcoming 5.0 release will feature a new protocol for our Edge Server that one will not feature channels.

The old XMPP protocol version still uses channels.

So, I have the 5.0 kit, it's windows edge server is 5.0 but it's linux server is 4.1.1.3, how do I get the linux 5.X version as the edge devices I will be working with are embedded arm linux? I am currently working under x86 linux to emulate them so a x86 version of the edge components would do.
