  - Improved reliability of calculating offsets in Pentax maker notes

May 26, 2005 - Version 5.22

  - Fixed problem with new '-tagsFromFile @' feature which occurred when
    simultaneously copying tags and writing new values to multiple target files
    (the new values were only getting written to the first file)

  - Added powerful new information redirection feature to -TagsFromFile option
  - Added writable File:FileModifyDate tag which represents the filesystem
    date/time of last modification
  - Allow '*' to also be used as well as 'all' to represent all tags, although

    more convenient since '*' must be quoted to prevent shell globbing

May 5, 2005 - Version 5.11

  - Fixed problem where the proper tags weren't excluded from being extracted if
    -GROUP:All and --TAG options are used together on the command line

May 5, 2005 - Version 5.10

        function calls

    notes to avoid writing a large preview to the destination file (now you have
    to do this manually afterwards if this is what you want)
  - Fixed problem rewriting Olympus E1 maker note subdirectories
  - Only validate extracted images when Binary (-b) option is used
  - Rename Olympus PreviewImageAvailable to PreviewImageValid, and check/set

    missing tags when the -f option is used
  - Account for different encoding of Canon ExposureTime in 20D and 350D, and
    lower priority of Canon ExposureTime and FNumber so regular EXIF values take
    precedence because it appears these values may be model dependent (I hate it
    when that happens)

Apr. 6, 2005 - Version 4.94

  - Added support for Kodak DX3215 and DX3700
  - Improved Kodak decoding and changed some Kodak tag names
  - Improved logic to guard against cyclical recursion in EXIF directories
  - Allow tags to be edited in IFD2, IFD3, etc...

    maker notes)

Mar. 9, 2005 - Version 4.84

  - Interpret Olympus ImageQuality of 6 as RAW
  - Remove validation of TIFF identifier to allow forward compatibility with
    untested RAW file formats (ORF files in particular seem to fiddle with this
    identifier)

Mar. 8, 2005 - Version 4.83

  - Extract ThumbnailImage from Canon CRW files written by some cameras
  - Recognize ORF files from Olympus C5060WZ (and hopefully some others too!)

    XMP-xmp)

Mar. 2, 2005 - Version 4.80

  - The -n option now prints binary data values as "Binary data #### bytes"
  - API Changes: (NOTE: Change in API behaviour for binary data values)
      - Changed returned ValueConv values so that binary data is now returned as
        a SCALAR reference, the same as with PrintConv values

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). Now special characters show up properly in my OSX terminal window, and
    the reverse translation works so now they get written properly as well (for
    Perl 5.6.1 or greater anyway... Earlier versions don't have the required
    UTF-8 support to handle these special characters)
  - Improvements to TagNames documentation (including changing format names to
    make them more consistent across different types of meta information)

  - Another try at patching 3 digit exponent situation which causes failed tests
    on MSWin32-x86
  - Removed .J2K from recognized extensions (since apparently this is a raw JP2
    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

    writable)

  - Improved CanonRaw verbose output
  - Remove garbage after null terminator in CanonRaw string-type tags

Jan. 30, 2005 - Version 4.45

  - Sort entries in synthesized Canon MakerNotes directory
  - Interpret Canon custom functions for models other than 10D in CRW files

Jan. 29, 2005 - Version 4.43

  - Synthesize Canon MakerNotes information when using -allTagsFromFile for a
    CRW file
  - Decode WhiteBalance table in Canon maker notes
  - Rename CanonRaw CanonFileType tag to CanonImageType

Jan. 28, 2005 - Version 4.42

    specific IPTC tag values with 'TAG-=VALUE'
  - Made EXIF SceneType writable
  - Changed name of Nikon ISOUsed tag to ISO

  - Added write support for Canon exposure parameters
  - Change validation of CanonPictureInfo to get it working for Canon 20D

Jan. 26, 2005 - 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:

    produces much prettier fractions)
  - Other minor improvements to writer code

Jan. 19, 2005 - Version 4.33

  - 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
  - Changed some warning messages
  - Documented the -m option (it's now official, even though it's been there
    since version 4.10)

Jan. 18, 2005 - Version 4.31

  - Now also copies over preview image in Nikon NEF files

Jan. 18, 2005 - Version 4.30

  - Now copies over preview images in EXIF data (large, external previews still
    not copied)
  - Account for funny offsets in Casio EX-Z3 maker notes while extracting data
    (but haven't figured out how to handle them when writing)
  - Fixed bug introduced in 4.20 that broke extraction of Canon PreviewImage

Jan. 17, 2005 - Version 4.23

  - Improve handling of unrecognized maker notes when writing

Jan. 17, 2005 - 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, 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
