The square mini has not been "discontinued" but it is no longer part of the permanent line of classic flap bags (designated 00V). Chanel has been choosing to release the mini as a seasonal bag in a variety of colors, materials, and sizes. I think because it is popular and at a lower price point, that they must sell a lot of them, so I don't see them discontinuing them altogether, but you can no longer find one in the original rigid caviar in black and beige; they are only in whatever Chanel decides to put them out in. I hope that makes sense.
