Nikon has posted the Capture 4.2 Updater. This update supports the D2x, improves the DEE and noise tools, and adds a number of small other tweaks and improvements.
Canto has introduced Cumulus 6.5, which mostly will appeal to multi-user setups, but does add user-creatable "actions," ICM support, and a host of other minor features.
dpMagic is now at version 1.1.015, which fixes some minor bugs and adds support for a number of additional cameras (only one Coolpix has been added on the Nikon side).
Noise Ninja is now officially available as a Photoshop plug-in.
Human Software has announced the 8th volume of Photoshop plug-in frames for images.
Adobe has a minor update (3.0.1) for Windows Photoshop Elements users. Also note that DNG Converter and Camera RAW module are both now in version 2.4.
