If you look at roadmap, they got everything out mostly in beta.

Plus many more outstanding features and bug fixes.

I'm waiting for the HDMI CEC Power Control "off" enhancement (that has finished Beta test) and the better utilization of the Ultra display with a proper VU meter and updated look and feel.

A few of us are waiting for naming/icon assigning for Smart Presets.

I think then there could be tweaks to the display.

But considering it was a pretty excellent finished product on release, it’s been on a hell if a journey.

It reach the end of roadmap. I don’t see anything new. After the beta get release officially we just get bug fix. Unlike before, we get consistent updates with feature after feature.
