The newest version is 2WCN34WW which was released last month. That version made these changes.....
Summary of changes

There are some earlier versions available on the server. You can find them by modifying the version numbers in Majestic's links.
Use them at your own risk.
 Looks like this was solved while I was posting. Never mind...
