looks good to me! I'm assuming the removing of all the items is from the legacy tracker.

My only question is - it looks like old line 41 was ensuring this was inserted in the HEAD - is there somewhere else that should be checked since that line was removed?

That line was only for the <meta> tag element that was previously needed for setting the Parse.ly apikey - as we're no longer adding that element, there's no need to put it in the head. As for the tracker itself, we explicitly don't recommend placing it in the document head.
