As you can see, dune releases now Alfa versions at http://dune-hd.com/dunecontrol/
Initially it was about remote controll and HTTP API. But till now they released there 3 updates, and included much more improvements, not only for API and the mobile app.
So even if you do not install, you can see the progress and what Dune is workin on. Release notes are available there.
I personally focused on testing mobile App, and I like it very much.
As I know, in the next release we can expect first version of BD4K Menu support. Desired and requested for a long time. Dune informed that they are closing final tests before public release. But it is not sure if they will release as alfa or beta or...
I also tested small patch for Netflix, that enables multichannel audio at Pro4k/Max4K and Ultra4K models. Worked well for me, so I home Dune will release it also quite soon.
I have no more news for now.
Thanks to the new API, we can expect new integration with smarthome systems soon. Maybe it is a value for some of you.
