75 <li> libtiff/{tif_luv.c, tif_next.c, tif_thunder.c}: Several buffer
76 overruns fixed, as noted by Chris Evans.
77
78 <li> BSD data types (u_char, u_short, u_int, u_long) is no longer
79 used internally in the libtiff. Should result in simpler configuration
80 and better portability.
81
82 <li> libtiff/tiff.h: Fix column tagging. Reference current Adobe XMP
83 specification. Reference libtiff bug tracking system to submit
84 private tag additions.
85
86 <li> libtiff/tif_dirread.c: Don't reject to read tags of the
87 SamplesPerPixel size when the tag count is greater than number of
88 samples as per bug

105 abcence of LZW support.
106
107 <li> libtiff/tif_dir.c: Call TIFFError() instead of producing warnings
