Thanks for the link. It certainly looks like it.

Yes.

Some audio outputs have changed to the new mode, some have not. It will come in some future minor releases.

In the new version, it also seems to actually change the volume a lot more drastically (at least above 100%), which is a good thing.

It used to be a linear scale, which is a nonsense. Now it use a quadratic scale (faster to compute than a log and close enough)

Interesting. I can't imagine that computers would have any trouble computing the log of a small integer many times per second.

No, but quadratic is faster and the result (here) is close enough to be good.
