Support for the AF-S NIKKOR 800mm f/5.6E FL ED VR has been added.

Frame output size has been changed from 95% to 100% when movie live view display is changed to "Information off" and an HDMI-compatible device is connected.
An issue that caused the right edges of images to be somewhat white when captured at an Image area setting of DX (24×16) 1.5x with Active D-Lighting set to Off has been resolved.
When the camera's shutter-release button was pressed repeatedly for uninterrupted shooting with the "Record to:" option in Camera Control Pro 2's Storage tab set to "PC+CARD", the camera would stop responding with displaying "Err" in its control panel. This issue has been resolved.
In some very rare cases, colors would change with shooting when white balance was set to a specific color temperature, as with Preset manual or Choose color temp. This issue has been resolved.
