I'm a little behind on new software and updates, but fortunately, there hasn't been an overwhelming amount to catch up on:
IOS: ShutterSnitch 2.2.0 recognizes personal hotspots, adds a rotation gesture, and fixes a few things. Timelapse Video Recorder is a simple app that mimics Nikon's Intervalometer feature (but has a far better interface for timelapse definition).
Computer: SubRosaSoft updated CameraSalvage to 7.5, gaining some operating system compatibility and updating their scan and recovery engine. Topaz Labs released Star Effects, a plug-in that creates radiant lighting and star effects. Digital Film Tools' Film Stocks is a plug in that mimics 288 color and black and white film stocks. DxO Labs released DxO Optics Pro 7.2 with a lot of new m4/3 camera support, plus new lens definitions. Akvis released version 1.5 of Refocus, adding support for raw files, new presets, and more. Adobe renamed Carousel--it's now called Adobe Revel--and updated it to version 1.1. Eye-Fi updated their firmware for X2 cards to version 5.001.
Mac-only: GraphicConverter 7.6 adds a bunch of adjustment tools, network scanner support, and bug fixes. PhotoSweeper 1.4 adds Aperture support and improved performance to their duplicate image finder. Exif Editor 1.0.5 adds support for many new tags and an option to remove all EXIF data. Photo Transformer 1.0 is a new photo manager that organizes photos on your computer no matter where they're physically located.
Windows-only: Photodex released Version 5 of ProShow Producer and Pro-Show Gold, my recommended slide show generator for Windows, with a new UI and lots of new features, some of them major.
