Feb. 21, 2005 - Version 4.66

Recognize JPEG 2000 XMP UUID information
Extract Meta information from JPEG APP3
Yet more playing with XP characters (this has been a learning process for me).

Decode JPEG 2000 Resolution, Label and URL information

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...)
API Changes:
- Added 'Compact' option to not write blank padding as per XMP and IPTC specs

Jan. 24, 2005 - Version 4.36 (production release)

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)

Fixed parsing problem with GPSProcessingMethod and GPSAreaInformation
No longer truncates 'undef' values at first null character
Changed all DataDump tags to binary data types

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):
- PentaxPictureMode => PictureMode
- PentaxFocusMode => FocusMode
- PentaxWhiteBalance => WhiteBalance
- PentaxAEMetering => MeteringMode
- PentaxFocalLength => FocalLength

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

Jan. 9, 2005 - Version 4.13

Added check on size of new ThumbnailImage so ExifTool doesn't try to write an image that is too large (>60k) into the JPEG EXIF APP1 segment
