Nikon today released version 2.4.4 of Capture NX2, their raw conversion tool. Additions include support for the Coolpix P7800 and a new underwater Auto Distortion capability for cameras that meet the requirements (e.g., the upcoming AW1). A number of small problems, mostly with the Windows version, have also been fixed.
Warning: we're likely to get another new version of Nikon Capture NX2 shortly, as there are several cameras coming out next month that are not currently supported.
