  47
  48 <ul>
  49         <li> LZW compression enabled by default. You don't need the separate
  50         compression kit anymore.
  51
  52         <li> bmp2tiff: Added new utility to convert Windows BMP files
  53         into TIFFs.
  54
  55         <li> The first attempt to implement a test suite.

  73
  74 <UL>
  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

  91
  92         <li> libtiff/{tiffio.h, tif_open.c}: Applied patches from
  93         Joris Van Damme to avoid requirement for tiffiop.h inclusion in
  94         some applications. Look for details here:

 102
 103         <li> libtiff/tif_lzw.c: LZW compression code is merged back from the
 104         separate package. All libtiff tools are updated to not advertise an
 105         abcence of LZW support.
 106
 107         <li> libtiff/tif_dir.c: Call TIFFError() instead of producing warnings
 108         when setting custom tags by value. Reported by Eric Fieleke.
