Version 1.2.1:
    - reduced memory footprint of exrenvmap and exrmaketiled 
      utilities.
    - IlmImf: new helper functions to determine whether a
      file is an OpenEXR file, and whether it's scanline- or
      tile-based.
    - IlmImf: bug fix for PXR24 compression with ySampling != 1.
    - Imath: a few new enhancements
    - Better support for gcc 3.4.
    - Warning cleanups in Visual C++.

Version 1.2:
    - Production-ready release.
    - Support for gcc 3.4.
    - Supports gcc 2.95 again.
    - IlmImf: bug fix for handling broken OpenEXR files without
      crashing.

Version 1.1.1:
    - Added Pixar's new "slightly lossy" image compression method
      for FLOAT channels, called PXR24.  HALF and UINT channels
      are compressed without loss.
    - Changed top-level LICENSE file to allow for other copyright
      holders for individual files.
    - Reading tiled files with the scanline interface is faster.
    - OpenEXR now supports YCA (luminance/chroma/alpha) images with
      subsampled chroma channels.
    - IlmImf: various bug fixes.
    - The half class is now faster in some expressions.
    - New tiled file format.  The new format is incompatible with
      the format used by 1.1.0.

Version 1.1.0:
    - IlmImfExamples: Updated to include examples of how to use
      the tiling and mip/ripmapping interfaces.
    - exrmakepreview: A new utility for embedding preview images
      in OpenEXR files.
    - exrenvmap: A new utility for creating OpenEXR environment maps.
    - exrstdattr: A new utility for manipulating standard attributes.
    - exrdisplay: Support for tiled, mip/ripmapped images, display
      windows, and preview images.
    - exrmaketiled: A new utility which generates tiled versions
      of OpenEXR images.
    - exrheader: Support for tiles, mipmaps, environment maps.
    - IlmImf: Support for environment maps.
    - IlmImf: Support for abstracted stream I/O.  You can
      wrap the IStream and OStream classes around your API
      of choice (FILE *, fd, even an HTTP 1.1 stream) as long
      as it supports seeking.
    - IlmImf: Support for tiled and mip/ripmapped files.  This
      requires a new file format.  Scanline files generated by
      the 1.1.0 version of the library can be read by older
      versions, but tiled files can only be read by 1.1.0 or
      greater.
    - Imath: added TMatrix*, generic 2D matricies and algorithms.
    - Imath: various updates and bug fixes.

Version 1.0.7:
    - Support for "optional standard" attributes:
	Primary and white point chromaticities.
	Absolute luminance.
	Content owner
	Comments
	Image acquisition time and place
	Focus distance
	Lens aperture
	Film sensitivity
      If you want to use these new attributes in your application, see
      ImfStandardAttributes.h for documentation on what they are and how
      to use them.
    - Bug fix in OpaqueAttributes.

Version 1.0.6:
    - Support for embedded preview images (thumbnails).
    - Automatic frame buffer type conversion.
    - Support for Visual Studio .NET 2003 w/ Microsoft's C++ compiler.
    - Minor bug fixes.

Version 1.0.5:
    - PIZ decoding should be 20-60% faster on Athlon and Pentium 4
      systems.
    - exrdisplay supports hardware rendering with vp30 profile fragment
      shaders.
    - Support for Win32 with Visual Studio 6.0 and Intel C++ compiler
      version 7.0.
    - Support for gcc 2.95.
    - New exrheader utility.
    - exrdisplay works on Win32 and OS X now.
    - Minor bug fixes.

Version 1.0.4:
    - Released under the new modified BSD license.

Version 1.0.3:
    - Even more OS X fixes.
    - Support for Metrowerks Codewarrior compiler.  Enables OpenEXR code
      to be used in a MacOS Photoshop plugin, if someone wants to write
      one. ;)
    - Fixed a bug in Imath, added some new confidence tests to ImathTest.
    - Other minor fixes.
    - Install include files.
    - exrdisplay requires fltk 1.1+ now.

Version 1.0.2:
    - More OS X fixes.
    - Fixed a rotation bug in Imath.

Version 1.0.1:
