Once of the new updates in ITScriptNet V2.4 is support for indexes on Validation Files larger than 16MB.  We've discussed this previously, and the update has been made in V2.4. 

Another new feature is support for Image Capture in the generic Windows Mobile 5 client.  Many WM5 smartphones and PDAs have a built in camera now, and Microsoft added a standard API to interface with it.  This means that we can support image capture using the camera on most consumer-grade Windows Mobile devices, without needing manufacturer-specific drivers or software. 

Rugged mobile computers, for the most part, have their own Imaging libraries written by the manufacturer and do not conform to the standard API.  These devices still require a device-specific client to support image capture.
