SonicOrbiter 2.7 is now released for all Sonore products, including microRendu, UltraRendu and Signature SE.
Have upgraded my UltraRendu from 2.6 to 2.7, without issue for the SonoreUPnP & RoonReady elements I use.
There are some additional handling of DACs for Native DSD support, which I can see in the profile of my XMOS based S/PDIF converter. I also believe there is native Qobuz support in the MPD module, but I can’t confirm this element.

I have also upgraded my UltraRendu to SonicOrbiterOS 2.8 and recently 2.9
