These have been around for a long time. Since the first movie actually. i checked back just now however and found a wealth of all new ones as well as the old ones, all archived. In case you knew nothing about them, they're basically all short one-shots in the setting of the Matrix movies. I've been really suprised by the quality of the writing and the art for a lot of them is simply outstanding.
check out the newest one entitled "Artistic freedom." It was written by Ryder Windham and drawn by killian Plunkett.
