Version 1.4.0.0: 01/10/2010

Custom Camera Info creation:
- CamCalibrate: A setup utility to calibrate a camera that has distortion/color aberration, launched from
menu bar > Setup > Calibrate Camera Distortion/Aberration.
- Runtime focal length calibration: After finished stitching a good photo set, select menu bar > Setup > Create/Update Focal Length to Camera Info File:  "Create" when no Camera Info file in current stitching, while "Update" when Camera Info file  as created for CamCalibrate is already used (to complete calibration with focal length).
Exif info (Exif~Exchangeable image file format): which is stored in photo files by the camera with info of comera model  / focal length, etc. Exif info is now utilized in CamCalibrate, settings and stitching, for auto-consistency  and robustness.
Smart Settings: with Exif info used from both photo set and Camera Info file, the seetings is validated/optimized when editing the Settings dialog and when start stitching, e.g., consistency of Camera Info file used with the stitching phto set. 
Stitch robustness: from Exif info plus custom Camera Info:
- A photo set with arbitrary zooming (focal length) changes and distortion can be stitched more robustly. 
Note that until now distortion correction was not allowed for a photo set with different focal lengths. 
- Image Pair Overlay method to stitch an image pair by visually adjusting their overlap: 
With focal length available in Camera Info, overlay method is always allowed even with arbitrary zooming.
This unique stitching feature is particularly useful with challenging scenes like wavy water.
