- IMPORTANT: Fixed bug introduced in 6.51 which could result in a corrupted
image (!!) when rewriting TIFF-format files containing an unknown trailer
(this includes all TIFF-based RAW formats except CR2). The good news is
that unknown trailers should be very uncommon, and nobody has reported any
problems yet, so with any luck I caught this before it affected anyone. But
please update immediately to 6.53 if you downloaded 6.51 or 6.52.

-GROUP:All and --TAG options are used together on the command line

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

Feb. 14, 2005 - Version 4.62
- Convert XPTitle, XPComment, XPKeywords etc from XP character codes and add
write support for these tags
- Decode JPEG 2000 Resolution, Label and URL information
- Another try at patching 3 digit exponent situation which causes failed tests
on MSWin32-x86

codestream, and doesn't contain any metadata that ExifTool can extract)
Feb. 14, 2005 - Version 4.61
- Don't print filename line when -p option used
- JPEG 2000 improvements
- Also recognize .JPX and .J2K extensions

allowed to add or delete any new tags (just as with the MakerNotes), except
for JpgFromRaw, which I like to be able to delete to save disk space
- 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:

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

- Added check at higher level and return warning if trying to delete
information from maker notes
- 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

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

- Improved logic in determining byte ordering of maker notes
Jan. 10, 2005 - Version 4.14
- Fixed problem introduced in 4.13 that messed up new 4.12 features. doh.
(and added test to keep this from happening again!).
- No longer store bad directory data as a tag (dump in verbose output instead)
Jan. 9, 2005 - Version 4.13

an image that is too large (>60k) into the JPEG EXIF APP1 segment

references to indicate lists of values if PrintConv is disabled
