The big news is Lightroom 4.1 and Adobe Camera Raw 7.1, which add D800 support and 8 new lens profiles for Nikon users. Likewise, DxO 7.5 is now 64-bit and also supports D800 files. On the Macintosh, Apple Digital Camera Raw Compatibility Update 3.13 added support for the D800E and D3200.
Apple also updated Aperture to version 3.2.4, which is mostly a bug fix.
On iOS devices, Facebook released their camera application, appropriately titlted Facebook Camera. Meanwhile, Photosmith 2.0 is a complete revamp of their iPad application, with many more useful cataloging features and better Lightroom integration. It also includes support for cameras using Eye-Fi cards, which, of course, includes the D800.
