Canon have now made DPP 3.2 (actually 18.104.22.168) available for download. The major features added since DPP 3.1 are:
Full support for the EOS 1Ds MkIII and EOS 40D have been added.
Automatic correction for vignetting, distortion and chromatic aberration when used with some EOS lenses. Notably missing are the EF-S 17-85/3.4-5.6IS USM and all of the 70-xxx telephoto zooms, as well as the 50/1.8 II (though the 50/1.2L and 50/1.4 are both included in the list). Hopefully Canon will be adding more lenses in future DPP updates. You can't make these corrections with lenses not on the list, even in a fully manual mode and Correction scan only be made on RAW files, the correction functions are not available with JPEGs.
DPP 3.2 now allows you to indicate areas of the image which are overexposed (luminance 255) or underexposed (luminance 0).
DPP 3.2 can be downloaded from http://software.canon-europe.com/software/0027547.asp. Note that this is a 24MB download, so it will take some time for those still on a dialup connection.
Here are few comments on the lens aberration correction function from the DPP 3.2 documentation:
...You can easily make corrections to drops in peripheral illumination, distortions in the subject, and color blur which occur by the physical characteristics of the lens or slightly remaining aberration. Please note that with Digital Photo Professional ver. 3.2, you can only correct RAW images which you have taken with the compatible cameras and lenses listed below. JPEG or TIFF images cannot be corrected.

|*1||Lens aberration correction functions cannot be used for the image taken with the combination of the lenses*1 and EOS 5D camera, since it is incompatible.|
|*2||Lens aberration correction functions cannot be used for the image taken with the combination of the lenses*2 and EOS 5D camera whose firmware version is 1.0.5 or older, since it is incompatible.|
|*3||Lens aberration correction functions cannot be used for the image taken with the combination of the lenses*3 and EOS 30D camera, since it is incompatible.|
|*4||Lens aberration correction functions cannot be used for the image taken with the combination of the lenses*4 and EOS 30D camera whose firmware version is 1.0.4 or older, since it is incompatible.|
You can make corrections to one of the four aberrations as below or to the multiple
aberrations at a time.
Peripheral illumination, distortions, chromatic aberration (color fringing which occurs in the periphery of an image), color blur (blue or red color blur which sometimes occurs at the edge of the highlighted area of an image)
