We updated the image resolution so now it will resize (by dragging the corner of the image) and not get blurry or pixelated, like old g(Math) did.
Old g(Math) had a 2x,3x, and 4x button to change the size. We now use the 4x resolution by default.
Some expressions will look differently in new g(Math) versus old g(Math), but we think it is a great improvement to be able to scale it.
This is especially useful if you want to copy and paste a g(Math) image into a Google Slide, which is a great instructional use case.
