• Professor Taubman informed the Kakadu community on Saturday, 10 July 2010 that he discovered a bug in version 6.4 of kdu_server that can cause it to crash, and said "I will work on fixing this ASAP, and release details of the fix."
• Professor Taubman informed me on Monday, 12 July 2010 that he will modify the behavior of kdu_expand -com, so that it does not unnecessarily consume CPU time to expand the .jp2 file, and as a result displaying JP2 comments will be much faster.
• A welcome addition would be for the file documentation/Usage_Examples.txt to include an example of using kdu_compress and kdu_expand with the -com option, to write and read JPEG2000 COM 0xff64 comment text boxes. Usage_Examples.txt is widely distributed for free with the Kakadu demostration applications for Apple Mac OS X, Sun Solaris, Mandrake Linux, and Microsoft Windows.

1. Added support for the BigTIFF file format to the "kdu_compress" and "kdu_expand" demo applications by modifying Kakadu's `kdu_tiff' class to support both regular TIFF and the new BigTIFF format -- modifications to "image_in.cpp" and "image_out.cpp" to support BigTIFF were almost negligible, but modifications to the `kdu_tiff' class that they use for TIFF support were more substantial. In any event, you can now read and write TIFF files much larger than 4GB in size. Suggested by Greg Coats. [The code in apps/image/image_out.cpp on line 1670 causes kdu_expand to use BigTIFF when writing .tif files that will have more than 3,600,000,000 bytes of pixels.]
2. Slightly modified "kdu_compress" and "kdu_expand" so that they read/write XMP and IPTC metadata found in TIFF files and JP2 files, as suggested by Greg Coats.
3. Added the resolution scaling adjustments suggested by Greg Coats to GeoJP2 information written back to TIFF files by "kdu_expand", so that any resolution reduction is taken into account. Simultaneously modified the way in which display resolution attributes are adjusted, so that resolution information recorded in the output file (BMP or TIFF) remains correct under both resolution reduction and cropping to a region of interest.
4. Fixed a bug in the TIFF reading code used by the "kdu_compress" demo application, which causes LZW compressed tiled images to be read incorrectly. Problem reported by Greg Coats, with fix provided by Margaret Lepley.
5. Removed the second writing of TIFF tag RowsPerStrip when generating GeoJP2 boxes in "image_in.cpp", which was a typo. This fix was provided by Greg Coats.
