- Decoded a few more Canon and CanonRaw tags
- Added -z option to extract information from images in compressed files
- Improved CanonRaw verbose output
- Remove garbage after null terminator in CanonRaw string-type tags
Jan. 30/05 - Version 4.45

- Sort entries in synthesized Canon MakerNotes directory
- Interpret Canon custom functions for models other than 10D in CRW files
Jan. 29/05 - Version 4.43

- Added write support for Canon exposure parameters

Jan. 26/05 - Version 4.40
- Added ability to write Canon RAW (CRW) files. With this format you aren't
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.

- 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. 19/05 - 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.)
- Fix parsing problem with GPSProcessingMethod and GPSAreaInformation
- No longer truncates 'undef' values at first null character
- Changed all DataDump tags to binary data types
- Changed some warning messages

since version 4.10)

Jan. 18/05 - Version 4.31

not copied).

(but haven't figured out how to handle them when writing)

- Improve handling of unrecognized maker notes when writing
Jan. 17/05 - Version 4.22
- Added check in -AllTagsFromFile to test for pointers in the maker notes
directory running outside the maker notes data. If they do, a warning is
issued and the maker notes are rebuilt properly before copying.
- Fixed problem which could corrupt some values when editing maker notes.
Jan. 17/05 - Version 4.21
- Added Olympus Red/BlueBalance
Jan. 17/05 - 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

- PentaxWhiteBalance => WhiteBalance

- PentaxFocalLength => FocalLength
- PentaxZoom => DigitalZoom
- PentaxSaturation => Saturation

(thanks to Christian Koller)
- Improved write logic for EXIF information
- Improved logic in determining byte ordering of maker notes
Jan. 10/05 - 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. 9/05 - 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.
Jan. 9/05 - Version 4.12
- -AllTagsFromFile option now copies over the maker notes
