<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>

<UL>

        <LI> configure: added test for libc6 for linux targets.  Bug reported by 
        Stanislav Brabec <utx@k332.feld.cvut.cz>

         <LI>	configure: fixed bugs in sed scripts 
	(applied sed script s:/@:s;@:;s:/s;;:;: to configure). 
	fix submitted by Stanislav Brabec <utx@k332.feld.cvut.cz>

	<LI> tools/iptcutil was not in files list, and wasn't being 
	added to tar archive.  Updated Makefile.in.

        <LI>  Added 3.5 docs to html/Makefile.in.  
	Thanks to  Stanislav Brabec <utx@k332.feld.cvut.cz>

        <LI> Fixed tools/tiffcmp so that stopondiff testing works.
	     Patch care of Joseph Orost <joe@sanskrit.lz.att.com>.

        <LI> Added fax3sm_winnt.c to distribution list in Makefile.in. 

         <LI> Added libtiff/libtiff.def to TIFFILES distribution list.
</UL>

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

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


<UL> 
        <LI>tif_fax3.c: Fixed serious bug introduced during the uint16->uint32 
        conversion for the run arrays.  

	<LI> Set td_sampleformat default to SAMPLEFORMAT_UINT instead of 
	SAMPLEFORMAT_VOID in TIFFDefaultDirectory() in tif_dir.c.

        <LI> Added "GetDefaulted" support for TIFFTAG_SAMPLEFORMAT in tif_aux.c.

	<LI> Patched tif_fax3.c so that dsp->runs is allocated a bit bigger
	to avoid overruns encountered with frle_bug.tif.

        
	<LI> 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).

	<LI> Modified tif_win32.c to support 2-4GB seeks.

	<LI> tentatively changed toff_t to be unsigned instead of signed to
	  facilitate support for 2-4GB files. 

	<LI>  Updated a variety of files to use toff_t.  Fixed some mixups
	      between toff_t and tsize_t.

	<LI> Set tif_rawdatasize to zero when freeing raw data buffer in
	     TIFFWriteDirectory().

         <LI> Enabled "REWRITE_HACK" in tif_write.c by default.
        
         <LI> Fix bug in tif_write.c when switching between reading one directory
	      and writing to another. 

         <LI> Made TIFFWriteCheck() public, and added TIFFCreateDirectory()

         <LI> Added TIFFmemory(3t) functions to libtiff.def.

         <LI> Added libtiff/libtiff.def to TIFFILES distribution list.
</UL>

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

<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>

<UL>
	<LI> fax2ps: Fixed mixup of width and height in bounding box statement
	as per submission by Nalin Dahyabhai <nalin@redhat.com>.

	<LI> fax2ps:  Modified printruns to take uint32 instead of uint16.  
	Patch courtesy of Bernt Herd <herd@herdsoft.com> 


	<LI> Largely reimplemented contrib/addtiffo to avoid temp files, 
 	    updating the TIFF file in place.  Fixed a few other bugs to.

       <LI> Altered descriptions in tools to reflect "by default" lzw not supported
</UL>

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

<A NAME="lzwkit"><B><FONT SIZE=+3>C</FONT>HANGES IN THE LZW COMPRESSION KIT</B></A>
<UL> 
	<LI>created mangle-src.sh -- sed scripts to munge src into LZW enabled format. Thanks to Stanislav Brabec <utx@k332.feld.cvut.cz>
	
	<LI>created Makefile
	
	<LI>merged  tif_dir.c with current source. 


	<LI>  Created lzw compression kit, as a new CVS module (libtiff-lzw-compression-kit). 

	<LI>  Updated index.html to note lzw compression kit.
