While GNOME 44.3 was skipped for some reason

What does this mean? I’m currently running 44.3, at least according to my system settings.

Why is the image showing a non official panel ? Have they added that as an option?

To have that layout, I have installed several extensions. Will I need no extensions to achieve that result in GNOME 44.4?

Or is this some random pic that they grabbed without thinking about it?
