Documentation feature request : in which version appeared features

When reading the documentation http://www.datatables.net/usage/columns
we can see that fnRender (for example) is deprecated.

It would be nice to write since which version it's deprecated, like "[Deprecated since 1.9.0]".
Same thing could apply to the new features, like "mRender [New since 1.9.0]".
(I also note that code example for deprecated features is gone.)

So people with old versions and not willing to change are aware of what was available in the good ol' days.

Thanks for this great add-on.
