This document describes the changes made to the software between the
<I>previous</I> and <I>current</I> versions (see above).  If you don't
find something listed here, then it was not done in this timeframe, or
it was not considered important enough to be mentioned.  The following

<A NAME="highlights"><B><FONT SIZE=+3>M</FONT>AJOR CHANGES:</B></A>

<UL>

	<li> Support for configure/build using CMake.
	<li> Support for large (> 2GB) files under Microsoft Windows.

</UL>

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

<UL>

  <LI> CMakeLists.txt / CMake
    <UL>
      <LI> Configuration and building using CMake is now supported
      under Microsoft Windows and on Unix-type systems.
    </UL>
  </LI>

  <LI> configure.ac / configure
    <UL>
      <LI> Test for and use fseeko() if it is available.  This allows
      supporting large files on Unix-type systems with a 32-bit 'long'
      type and a 64-bit 'off_t' type.
    </UL>

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

<UL>

    <LI> tiffiop.h:
    <UL>
      <LI> Macros added to use 64-bit equivalents for all standard I/O
      and POSIX APIs used by libtiff and its tools which are limited
      to 2GB in Windows builds.  Note that these 64-bit equivalents
      were introduced by the CRT provided with Visual Studio 2005 and
      if the necessary CRT is not installed on the target computer,
      the program will not run.  The wrapper macros will not be
      activated unless the definition _MSC_VER is at least 1400 or
      __MSVCRT_VERSION__ is at least 0x800.
    </UL>

  <LI> tif_unix.c:
    <UL>
      <LI> Updated to support large files under Microsoft Windows.
      This makes tif_unix.c a completely viable candidate for use
      under Windows (in spite of its name) if the CRT is modern
      enough.  Please note that tif_win32.c already supported large
      files, but only 'tiffinfo' and 'tiffdump' made any provision to
      support large files under Windows.
      <LI> _tiffReadProc() and _tiffWriteProc() are modified to chunk
      I/O to a maximum size of 2GB for extremely large I/O
      requests. This surmounts limitations in the Microsoft Windows
      read() and write() APIs (which are limited to the range of a
      32-bit 'int'), and may avoid poor behavior with extremely large
      I/O requests on other systems.
    </UL>
