Status of Callbacks

[David Wheeler]

Hi All,

I just noticed that, while the Callbacks attribute has been  
implemented in SVN, it still hasn't made it into a release. I could  
have sworn that it was a long time ago that I worked on them. And  
didn't I write some docs for them?

So, what's the status on Callbacks? Are they ready to go into a release?

Thanks,

David
