+<A NAME="highlights"><B><FONT SIZE=+3>M</FONT>AJOR CHANGES:</B></A>
+
+<UL>
+	<li> New <b>tiffcrop</b> utility contributed by Richard Nolde.
+	<b>tiffcrop</b> does the same as <b>tiffcp</b>, but also can crop,
+	extract, rotate and mirror images.
+
+	<li> tif_jbig.c:  Added	support for JBIG compression scheme
+	(34661 code), contributed by Lee Howard.
+
+	<li> Totally new implementation of OJPEG module from
+	Joris Van Damme. No need to patch libjpeg anymore. Many OJPEG files
+	should be supported now that was not supported previously.
+
+</UL>
+

+<!--------------------------------------------------------------------------->
+
+<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
+
+<UL>
+
+	<li> tif_config.wince.h, tiffconf.wince.h, tif_wince.c: WinCE-specific
+	compatibility stuff from Mateusz Loskot.
+
+	<li> Rename config.h.vc and tif_config.h.vc to config.vc.h and 
+	tif_config.vc.h for easier identification by folks using an IDE.
+
+	<li> configure, configure.ac: OJPEG support enabled by default (i.e.,
+	whe the conformant JPEG support enabled).
+
+	<li> README.vms, Makefile.am, configure.com, libtiff/{Makefile.am,
+	tif_config.h-vms, tif_stream.cxx, tif_vms.c, tiffconf.h-vms}:
+	Added support for OpenVMS by Alexey Chupahin.
+
+	<li> nmake.opt: use /EHsc for VS2005 compatibility.  Also define
+	_CRT_SECURE_NO_DEPRECATE to avoid noise on VS2005.
+
+</UL>

+<!--------------------------------------------------------------------------->
+
+<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
+
+<UL>
+	<li> tif_dirinfo.c (_TIFFFindFieldInfo): Don't attempt to
+	bsearch() on a NULL fieldinfo list.
+	(_TIFFFindFieldInfoByName): Don't attempt to lfind() on a NULL
+	fieldinfo list.
+
+	<li> tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it
+	will convert from decompressor to compressor or compress to decompress
+	if required by the force arguments.  This works around a problem in
+	where the JPEGFixupTestSubsampling() may cause a decompressor to 
+	be setup on a directory when later a compressor is required with the
+	force flag set.  Occurs with the addtiffo program for instance.
+
+	<li> tif_dirwrite.c: Fixed swapping of byte arrays stored
+	in-place in tag offsets as per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1363">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1363</a>
+
+	<li> tif_getimage.c: workaround for 'Fractional scanline' error
+	reading OJPEG images with rowsperstrip that is not a multiple of
+	vertical subsampling factor. This bug is mentioned in
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1390">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1390</a> and
+	<a href="http://www.asmail.be/msg0054766825.html">
+	http://www.asmail.be/msg0054766825.html</a>
+
+	<li> tif_dirread.c: Added special function to handle
+	SubjectDistance EXIF tag as per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1362">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1362</a>
+
+	<li> tif_dirread.c, tif_read.c: Type of the byte counters
+	changed from tsize_t to uint32 to be able to work with data arrays
+	larger than 2GB. Fixes bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=890">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=89</a>	
+	Idea submitted by Matt Hancher.
+
+	<li> tif_dir.c: Workaround for incorrect TIFFs with
+	ExtraSamples == 999 produced by Corel Draw. As per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1490">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1490</a>
+
+	<li> tif_write.c: TIFFAppendToStrip() - clear sorted flag if 
+	we move a strip.
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1359">
+		http://bugzilla.remotesensing.org/show_bug.cgi?id=1359</a>
+
+	<li> tif_fax3.c: Save the state of printdir codec dependent method.
+
+	<li> tif_jpeg.c: Save the state of printdir codec dependent method
+	as per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1273">
+		http://bugzilla.remotesensing.org/show_bug.cgi?id=1273</a>
+
+	<li> tif_win32.c: Fixed problem with offset value manipulation
+	as per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1322">
+		http://bugzilla.remotesensing.org/show_bug.cgi?id=1322</a>
+
+	<li> tif_fax3.c, tif_next.c, tif_pixarlog.c: Fixed multiple
+	vulnerabilities, as per	Gentoo bug ():
+	<a href="http://bugs.gentoo.org/show_bug.cgi?id=142383">
+	http://bugs.gentoo.org/show_bug.cgi?id=142383</a>
+
+	<li> tif_lzw.c, tif_zip.c: Fixed problems with mixing
+	encoding and decoding on the same read-write TIFF handle.  The LZW
+	code can now maintain encode and decode state at the same time. The
+	ZIP code will switch back and forth as needed.  
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=757">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=757</a>
+
+	<li> tif_msdos.c: Avoid handle leak for failed opens.
+	c/o Thierry Pierron
+
+	<li> tif_dirwrite.c: take care not to flush out buffer of strip/tile
+	data in _TIFFWriteDirectory if TIFF_BEENWRITING not set.  Relates
+	to bug report by Peng Gao with black strip at bottom of images.
+
+	<li> tif_dirwrite.c: make sure to use uint32 for wordcount in 
+	TIFFWriteNormanTag if writecount is VARIABLE2 for ASCII fields.
+	It already seems to have been done for other field types.  Needed
+	for "tiffset" on files with geotiff ascii text.
+
+	<li> tif_dirinfo.c: Added missed EXIF tag ColorSpace (40961).
+
+	<li> tif_dirread.c: Move IFD fetching code in the separate
+	function TIFFFetchDirectory() avoiding code duplication in
+	TIFFReadDirectory() and TIFFReadCustomDirectory().
+
+	<li>tif_readdir.c: Added case in EstimateStripByteCounts() for tiled
+	files.  Modified TIFFReadDirectory() to not invoke
+	EstimateStripByteCounts() for case where entry 0 and 1 are unequal but
+	one of them is zero.
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1204">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1204</a>
+
+	<li> tif_open.c, tif_dirread.c, tiffiop.h: Move IFD looping
+	checking code in the separate function TIFFCheckDirOffset().
+
+	<li> tif_aux.c: Added _TIFFCheckRealloc() function.
+
+	<li> tif_fax3.c: Fixed problems in fax decoder as per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1194">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1194</a>
+
+	<li> tif_jbig.c:  Added	support for JBIG compression scheme
+	(34661 code) contributed by Lee Howard. As per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=896">
+		http://bugzilla.remotesensing.org/show_bug.cgi?id=896</a>
+
+	<li> tif_getimage.c: Added support for planarconfig separate
+	non-subsampled YCbCr (i.e. separate YCbCr with subsampling [1,1]).
+
+	<li> tif_getimage.c: Revision of all RGB(A) put routines:
+	<ul>
+		<li> Conversion of unassociated alpha to associated alpha
+		now done with more performant LUT, and calculation more
+		correct.
+	  	<li> Conversion of 16bit data to 8bit data now done with
+	  	more performant LUT, and calculation more correct
+	  	<li> Bugfix of handling of 16bit RGB with unassociated alpha
+  	</ul>
+
+	<li> tif_ojpeg.c: totally new implementation
+
+	<li> tif_getimage.c: removed TIFFTAG_JPEGCOLORMODE handling
+	of OJPEG images in favor of tif_getimage.c native handling of
+	YCbCr and desubsampling.
+
+	<li> tif_jpeg.c: JPEGVSetField() so that altering the photometric
+	interpretation causes the "upsampled" flag to be recomputed.  Fixes
+	peculiar bug where photometric flag had to be set before jpegcolormode
+	flag.
+
