- Added validation of JpgFromRaw images
- Relax filtering on non-ASCII characters by exiftool script to allow high-ASCII characters to be printed
- Changed the tense of Orientation values to try to make the meaning more clear. This tag can be a bit confusing. It gives the rotation that must be applied to the image to view it properly (hence the rotation of the camera when the picture was taken).
- Patched problem which was causing failed tests on some platforms (floating point format has 3 digits in exponent on Perl 5.8.5 MSWin32-x86, grrrr...)

- Added more validation when writing IPTC information
- Fixed display of Nikon FlashExposureComp for negative values

- Fixed problem on systems that use backslashes in directory names that prevented exiftool from finding its libraries if not installed
- Changed many Pentax tag names to remove "Pentax" prefix and conform more to the other tag names (moving information between files of different formats is much easier if tags have standardized names):

- No longer store bad directory data as a tag (dump in verbose output instead)

Jan. 9, 2005 - Version 4.13
