And still no HDMI fix?

It has been in Beta Testing and approved. So why is it still not included?

This looks like being a release with minor, mostly unimportant updates, not including any of the important fixes or additions.

Let us hope for the next

What does “Refined the logic for default DAC filter selection” mean ..

Volume Feedback: The screen now wakes to show the volume bar when adjusting volume, even if the display was off.

I for one think that off should mean off.
Unless this is an option?
