Updating AWS ELB Classic External Service

I’m trying to use the stack mentioned in the headline featured here:

But unfortunately it is repeatedly restarting due to an issue fixed in this commit:

What is the process for getting the newest version of this stack into the catalog? Is there anything I can do to help with this?
