This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

- Changes in the software configuration
- Changes in libtiff
- Changes in the tools
- Changes in the LZW compression kit

CHANGES IN THE SOFTWARE CONFIGURATION:

- configure: added test for libc6 for linux targets. Bug reported by Stanislav Brabec
- configure: fixed bugs in sed scripts (applied sed script s:/@:s;@:;s:/s;;:;: to configure). fix submitted by Stanislav Brabec
- tools/iptcutil was not in files list, and wasn't being added to tar archive. Updated Makefile.in.
- Added 3.5 docs to html/Makefile.in. Thanks to Stanislav Brabec
- Fixed tools/tiffcmp so that stopondiff testing works. Patch care of Joseph Orost .
- Added fax3sm_winnt.c to distribution list in Makefile.in.
- Added libtiff/libtiff.def to TIFFILES distribution list.

CHANGES IN LIBTIFF:

- tif_fax3.c: Fixed serious bug introduced during the uint16->uint32 conversion for the run arrays.
- Set td_sampleformat default to SAMPLEFORMAT_UINT instead of SAMPLEFORMAT_VOID in TIFFDefaultDirectory() in tif_dir.c.
- Added "GetDefaulted" support for TIFFTAG_SAMPLEFORMAT in tif_aux.c.
- Patched tif_fax3.c so that dsp->runs is allocated a bit bigger to avoid overruns encountered with frle_bug.tif.
- Modified tif_unix.c to support 2-4GB seeks if USE_64BIT_API is set to 1, and added default (off) setting in tiffconf.h. This should eventually be set by the configure script somehow. The original work on all these 2-4GB changes was done by Peter Smith (psmith@creo.com).
- Modified tif_win32.c to support 2-4GB seeks.
- tentatively changed toff_t to be unsigned instead of signed to facilitate support for 2-4GB files.
- Updated a variety of files to use toff_t. Fixed some mixups between toff_t and tsize_t.
- Set tif_rawdatasize to zero when freeing raw data buffer in TIFFWriteDirectory().
- Enabled "REWRITE_HACK" in tif_write.c by default.
- Fix bug in tif_write.c when switching between reading one directory and writing to another.
- Made TIFFWriteCheck() public, and added TIFFCreateDirectory()
- Added TIFFmemory(3t) functions to libtiff.def.
- Added libtiff/libtiff.def to TIFFILES distribution list.

CHANGES IN THE TOOLS:

- fax2ps: Fixed mixup of width and height in bounding box statement as per submission by Nalin Dahyabhai .
- fax2ps: Modified printruns to take uint32 instead of uint16. Patch courtesy of Bernt Herd
- Largely reimplemented contrib/addtiffo to avoid temp files, updating the TIFF file in place. Fixed a few other bugs to.
- Altered descriptions in tools to reflect "by default" lzw not supported

CHANGES IN THE LZW COMPRESSION KIT

- created mangle-src.sh -- sed scripts to munge src into LZW enabled format. Thanks to Stanislav Brabec
- created Makefile
- merged tif_dir.c with current source.
- Created lzw compression kit, as a new CVS module (libtiff-lzw-compression-kit).
- Updated index.html to note lzw compression kit.
