  - Fixed problem deleting entire XMP data block using '-xmp=' syntax
  - More minor HtmlDump improvements

Dec. 12/05 - Version 5.84

  - Minor improvements to HtmlDump output

Dec. 12/05 - Version 5.83

  - Added -F option to allow maker notes offsets to be fixed
  - Added -htmlDump option to generate a verbose HTML-based hex dump of EXIF
    and/or TIFF information (cool new diagnostic tool)
  - Attempt to validate maker notes offsets and issue warning if they look wrong
  - Fixed problem rewriting PreviewImage in some Olympus and Pentax images
  - Increased speed for extracting large preview images
  - Improved synthetic maker notes when coping tags from CRW file
  - Display absolute offsets for EXIF values in very very verbose mode
  - Verbose option output is now written to file if -w option used
  - Speed up rewriting of some TIFF images when using ActivePerl 5.8.x for
    Windows (image strips are now copied in a single block if they are
    contiguous in the file to avoid ActivePerl bug which causes extremely poor
    performance when concatinating a large number of memory blocks)
  - Added a couple of new Nikon and Pentax lens ID's (thanks Robert Rottmerhusen
    and David Buret)
  - Decode PrintIM information in Casio QV-4000

  - Fixed bug which caused error rewriting Minolta MRW images
  - Added MRW write test
  - Improved MRW verbose output

Nov. 24/05 - Version 5.81

  - Changed writing of TIFF so that existing IPTC will be rewritten as int32u
    whenever IPTC is edited, regardless of original format type.  This allows
    files to be 'fixed' even if IPTC was previously another format (now we get
    to see if there is any software out there that barfs on int32u's...)
  - Changed the -s option so tag names are displayed instead of descriptions
    (now similar to the -S option, but values are aligned in a column)
  - Remove padding at the end of IPTC record when writing
  - Fixed problem which was generating a warning with ActivePerl 5.6.1

Nov. 22/05 - Version 5.80

  - Changed writing of new TIFF IPTC information to make it visible in Nikon
    Capture (for some reason requires int32u format)

  - Extract Red/BlueBalance tags for Nikon D2Hs, D50 and D2X
  - Decode Nikon Capture Data to extract IPTC information and Rotation
  - Added a new Olympus LensType (thanks Michael Meissner)

Oct. 28/05 - Version 5.72

  - Added ability to create XMP data files.  This is more significant than it
    sounds:  The -o option may now be used to generate XMP files from
    information in any other format, or even to create an XMP file from nothing
    more than tags defined on the command line.

      - Added ability to access original 'Raw' values via GetValue()
      - GetValue() now returns empty array in list context if value is undefined
      - Values are now converted as they are requested, so the PrintConv option
        now applies to GetInfo() and GetValue() instead of ExtractInfo()

Oct. 19/05 - Version 5.69

  - Changed UTF-8 bug fix introduced in 5.67 to improve portability and allow it
    to work with Perl versions back to 5.6
  - Changed some offsets in verbose output from relative to absolute addressing

    X/YResolution.  Neither has a corresponding ResolutionUnit tag, so inches
    should be assumed if no resolution unit is present
  - Added tests of Nikon, Sony and PDF decryption algorithms

Oct. 7/05 - Version 5.65

  - Added read support for QuickTime MOV videos (and QTIF images if anyone
    cares)
  - Extract maker note information from Sony SRF raw images
  - Improved Jpeg2000 decoding
  - Decode a few more Photoshop tags

    unsuported RAW image with a TIFF-like data structure)

    the errors which can be ignored with the -m option)

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

May 5/05 - Version 5.10

    the value data of an IFD entry (only effects Casio images)

        function calls

  - ALL MAJOR PLANNED WRITING FEATURES NOW IMPLEMENTED!
  - Finally solved problem of writing large preview images in JPEG files

    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
    this tag when reading/writing the preview image

    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)

    untested RAW file formats (ORF files in particular seem to fiddle with this
    identifier)

Mar. 8/05 - Version 4.83

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

    codestream, and doesn't contain any metadata that ExifTool can extract)

Feb. 14/05 - Version 4.61

  - Don't print filename line when -p option used
  - JPEG 2000 improvements

  - 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:

  - 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

    '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

  - Improve handling of unrecognized maker notes when writing

Jan. 17/05 - Version 4.22

    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 more validation when writing IPTC information
  - Fixed display of Nikon FlashExposureComp for negative values

    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):

      - PentaxFocusMode => FocusMode
      - PentaxWhiteBalance => WhiteBalance
      - PentaxAEMetering => MeteringMode

    Canonism
  - Improved logic to recognize more types of unknown maker notes

  - Renamed IPTC 'SupplementalCategory' to 'SupplementalCategories'
  - Handle timezone in times
  - API Changes:
