  78
  79         <li> libtiff/{tif_open.c, tiffio.h}: New function added:

  96                 http://bugzilla.remotesensing.org/show_bug.cgi?id=562</a>.
  97
  98         <li> libtiff/tif_write.c: Allow in-place updating of the compressed
  99         images (don't work properly with all codecs). For details see GDAL bug
 100         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=534">
 101                 http://bugzilla.remotesensing.org/show_bug.cgi?id=534</a>.

 105         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=532">
 106                 http://bugzilla.remotesensing.org/show_bug.cgi?id=532</a>.

 124                 http://bugzilla.remotesensing.org/show_bug.cgi?id=483</a>.
 125         We need more work on fax codec to support update mode.

 128         and TIFFTAG_INDEXED as per bug

 145
 146         <li> libtiff/tif_dirwrite.c: Fixed handling of writable ASCII tags
 147         that are field_passcount=TRUE properly.  Arguably anonymous custom
 148         tags should be declared as passcount=FALSE, but I don't want to change
 149         that without a careful review.
 150
 151         <li> libtiff/tif_write.c: Fixed reporting size of the buffer in case

 157         patch from Gerben Koopmans.

 159         <li> libtiff/tif_dirread.c: Check field_passcount value before setting
 160         the value of undefined type, patch from Gerben Koopmans.
 161
 162         <li> libtiff/{tiff.h, tif_fax3.c}:Fixes for AMD 64 platform as
 163         suggested by Jeremy C. Reed.
 164
 165         <li> libtiff/tif_win32.c: Fixed problem with _TIFFrealloc() when
