Hi Josh, yes I think we can merge this in the 2.4.0 final release, but we'll have to review a bit in more detail first. However, could you create a JIRA issue containing a link to the patch?
thanks!

I think we can work with pull requests on github, as long as we see clearly the diffs with the code in the svn repository we should be fine. @Maarten, Nicolas, and others in the Ivy community, do you think we can merge this before building the ivy 2.4.0 final ?
