<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<li> libtiff/{tif_luv.c, tif_next.c, tif_thunder.c}: Several buffer
overruns fixed, as noted by Chris Evans.
<li> BSD data types (u_char, u_short, u_int, u_long) is no longer
used internally in the libtiff. Should result in simpler configuration
and better portability.
<li> libtiff/tiff.h: Fix column tagging. Reference current Adobe XMP
specification. Reference libtiff bug tracking system to submit
private tag additions.
<li> libtiff/tif_dirread.c: Don't reject to read tags of the
SamplesPerPixel size when the tag count is greater than number of
samples as per bug
<A HREF="http://bugzilla.remotesensing.org/show_bug.cgi?id=576">
http://bugzilla.remotesensing.org/show_bug.cgi?id=576</A>.
<li> libtiff/{tiffio.h, tif_open.c}: Applied patches from
Joris Van Damme to avoid requirement for tiffiop.h inclusion in
some applications. Look for details here:

<li> libtiff/{tiffiop.h, tif_dirinfo.c}: Fixed problem with the static
variable as per bug

<li> libtiff/tif_lzw.c: LZW compression code is merged back from the
separate package. All libtiff tools are updated to not advertise an
abcence of LZW support.
<li> libtiff/tif_dir.c: Call TIFFError() instead of producing warnings
when setting custom tags by value. Reported by Eric Fieleke.
