	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=826">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=826</a>

	<li> configure.ac, libtiff/Makefile.am: Use libtool machinery to pass
	rpath option.

	<li> make.opt: Build with Win32 CRT library by default.
</UL>

<P><HR WIDTH=65% ALIGN=left>

<!--------------------------------------------------------------------------->

<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>

<UL>
	<li> tiffiop.h, tif_open.c: Added open option 'h' to avoid reading
	the first IFD when needed. As per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=875">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=875</a>

	<li> tiff.h: Use correct int size on Sparc 64bit/Sun compiler
	platform. As per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=855">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=855</a>

	<li> tif_dirinfo.c: Added support for ClipPath, XClipPathUnits
	and YClipPathUnits tags.

	<li> tif_dirinfo.c, tif_dir.h, tif_dir.c, tif_print.c: Make
	DocumentName, Artist, HostComputer, ImageDescription, Make, Model,
	Copyright, DateTime, PageName, TextureFormat, TextureWrapModes and
	TargetPrinter tags custom.

	<li> tif_jpeg.c: Cleanup the codec state depending on TIFF_CODERSETUP
	flag (to fix memory leaks).

	<li> tif_dirwrite.c: Use tdir_count when calling
	TIFFCvtNativeToIEEEDouble() in the TIFFWriteDoubleArray() function as
	per bug <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=845">
	http://bugzilla.remotesensing.org/show_bug.cgi?id=845</a>

	<li> tif_dirinfo.c, tif_print.c: TIFFFetchByteArray() returns
	uint16 array when fetching the BYTE and SBYTE fields, so we should
	consider result as pointer to uint16 array and not as array of chars.
	As per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=831">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=831</a>

	mode in CreateFile() call as per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=829">
	http://bugzilla.remotesensing.org/show_bug.cgi?id=829</a>

	<li> tif_jpeg.c: Substantial fix for addtiffo problems with
	JPEG encoded TIFF files.  Pre-allocate lots of space for jpegtables
	in directory.

	<li> tif_dirread.c: Changed the code that computes
	stripbytecount[0] if it appears bogus to ignore if stripoffset[0] is
	zero. This is a common case with GDAL indicating a "null" tile/strip.

	<li> tif_jpeg.c: added LIB_JPEG_MK1 support in JPEGDecodeRaw().

	<li> tif_dirread.c: Ensure that broken files with too many
	values in PerSampleShorts, TIFFFetchPerSampleLongs and
	TIFFFetchPerSampleAnys work ok instead of crashing.
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=843">
	http://bugzilla.remotesensing.org/show_bug.cgi?id=843</a>

	<li> tif_predict.h, tif_predict.c: Added ability to decode and encode
	floating point predictor, as per TIFF Technical Note 3.
	See http://chriscox.org/TIFF_TN3_Draft2.pdf for details.

	<li> tiffio.h, tiffiop.h, tif_dir.c, tif_read.c, tif_swab.c:

	<li> tiff.h: Added predictor constants.

	<li> tiffiop.h, tif_dir.c: Use uint32 type for appropriate values
	in _TIFFVSetField() function. Inspired by the bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=816">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=816</a>

	<li> tif_open.c: Do not read header in case the output file should
	be truncated (Ron).

	<li> tif_dirinfo.c, tif_config.h.vc: Use lfind() instead of bsearch()
	in _TIFFFindFieldInfoByName() function (Ron).

	<li> tif_dir.c, tif_print.c: Properly handle all data types in custom
	tags.

	<li> dirinfo.c: Added DNG tags.

	<li> tiff.h: Added missed DNG tag (LensInfo); added DNG 1.1.0.0 tags.

	<li> tif_dir.c, tif_print.c: Added Support for custom tags, passed

	the fscanf() function. As per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=861">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=861</a>

	<li> tiffsplit.c: Check for JPEGTables tag presence before copying.
