Noticed this morning during Good Day, no more revolving red-blue box (even though it remains in the news open), different background and treatment of lower-third graphics (but lettering font is pretty much the same), plus during some stories, instead of left-shoulder/right-shoulder pix and captions next to the anchors, the caption was in the middle lower-third, the picture or graphic was on the right side of the lower-third, and the anchor was centered on the screen. The "Fox 4" part of the bug disappears and reappears occasionally also. Here's a screenshot from this morning:
