New method Javadoc version ?

[Tom Zeller]

It seems like we should add some sort of @version or @since annotation to methods we add to Actions, now that we are post-dot-zero.

For example, I want to add a property setter to an Action, for which the existence of the property enables a particular behavior.

But I don't know what annotation to use, because I think it should be a macro that gets set based on the version in the Maven POM.
Anybody know ?
