One of the important new features of Adobe Photoshop CC is new additions to the shapes tool. You can now create all sorts of different shapes by rounding each corner of a shape separately.
In Photoshop CS6, the new version of Photoshop, you can use special cropping tool and you are done, but that doesn't mean you cannot achieve the same result with older versions.
Another new and interesting feature of the updated Photoshop CC that enables you to save layers directly into image files without clicking the Save button.
