Msterious ExceptionInfo parameter in docs?

[qrilka]

Take a look at function SetImageAlphaChannel
in API docs http://www.imagemagick.org/api/MagickCo ... 70ca28ebfc I see 3 parameters
and in svn for verion 6.7.8 (like in API docs) - http://trac.imagemagick.org/browser/Ima ... age.h#L529 - 2 parameters
What should it mean?

We'll have a fix in a few hours. The mysterious exception parameter is from ImageMagick 7.0.0 Alpha.
