Adobe maintains a list of supported for their image editing applications (Photoshop, Lightroom, Photoshop Elements). You can find that list here.
Both lists are regularly updated as new camera models are released. Updates to the images editing software should be automatic.
If you are considering the purchase of a digital camera that shoots RAW, you should consult these lists first to make sure the camera you buy will be compatible with the editing software you plan to use.
