Difference Between Canon EF 28mm f/2.8 IS USM and Canon EF 28mm f/2.8 lenses

Hi all.
I just googled the 28mm Canon lens and I got two results:
1. Canon EF 28mm f/2.8 IS USM
2. Canon EF 28mm f/2.8

Besides price, what is the difference between these two lenses? The description sounds the same, but one is priced higher than the other. I'm puzzled what the diference is.

IS means image stabilization. It's useful when operating your camera handheld in dark settings.

USM means the lens is equipped with a fast and silent focus motor.

The USM version is the newest version of the other one (which came out in 1987).

Both lenses are soft wide open.
