Today Nikon announced ViewNX 2.7.5 and Capture NX 2.4.2. The only modification in the new versions is related to the Nikon D600:
When RAW images captured with a D600 running C firmware Ver. 1.01 at an Image area setting of DX (24×16) 1.5× and any Active D-Lighting setting other than Off were opened in ViewNX 2 or Capture NX 2, a bright (whitish) diagonal line was visible. This issue has been resolved.
With the latest move from Adobe to a monthly subscription plan for future Photoshop CC releases, Nikon has the unique opportunity to revamp their Capture NX software and gain some significant market share since I believe many users will be looking for an alternative solution in the coming months.
