This logo is similar to the 2007 one, but the font used for the wordmark is different, the registered trademark symbol is closer to where the second vertical line and horizontal line intersect, the box and shadows are removed, the gradients are removed, and the "H" is green and is rendered in a flat bitmap file. It's used in tandem with both the 2007 and 1983 logos.
