  - 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 'Compact' option to not write blank padding as per XMP and IPTC specs

  - Make GPS latitude and longitude a bit more flexible about the format they accept when writing
  - Updates to documentation
  Jan. 19, 2005 - Version 4.32
  - Now rewrites Casio EX-Z3 maker notes properly (well, not actually 'properly', but the way they were written in the first place, which is wrong)
  - Added warning when writing information if original IFD entries were not in the proper sequence, which is a violation of EXIF specs. (And surprise, you'll never guess who does this too... Yup, the EX-Z3.)
  - Fixed parsing problem with GPSProcessingMethod and GPSAreaInformation
  - No longer truncates 'undef' values at first null character
  - Changed all DataDump tags to binary data types

  - Improve handling of unrecognized maker notes when writing
  Jan. 17, 2005 - Version 4.22

  Jan. 17, 2005 - Version 4.21
  - Added Olympus Red/BlueBalance
  Jan. 17, 2005 - Version 4.20
  - Added ability to edit MakerNotes!
  - Added more validation when writing IPTC information
  - Fixed display of Nikon FlashExposureComp for negative values
  - Fixed problem where the large JPEG image in Nikon and Pentax raw files was misidentified as the ThumbnailImage. It is now extracted as JpgFromRaw. This allows all 3 JPEG images contained in Pentax PEF files to be extracted: ThumbnailImage, PreviewImage and JpgFromRaw.
  - 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):

  - Improved write logic for EXIF information
  - Improved logic in determining byte ordering of maker notes
  Jan. 10, 2005 - Version 4.14

  - No longer store bad directory data as a tag (dump in verbose output instead)
  Jan. 9, 2005 - Version 4.13
