I can’t quite place why but it is slightly less easy on the eye. Maybe the shading gradients of the background and the post background or the spacing between posts or something else. No setting brings back the complete relaxed eye feeling I used to have whether feed style or font size.

We haven't changed the background, but we definitely did work on the spacing of content quite a bit. We wanted a denser look, so that it is more in line with what the mainstream social apps are doing (and what most users out there are used to).
Maybe this is a matter of getting used to it? I've had the same feeling when switching from our old layout, but I now much prefer the new ones. The old one looks a bit pedestrian to me when I try the previous build of the app.
In any case, thank you for the feedback and keep it coming!
