Technically speaking, just the changes to the upgrade guide are needed. I have added a separate commit for removing the now unnecessary index from the stub migration for the reasons I detail in the linked issue.
I don't think this qualifies as a breaking change, but I can remove that commit if you'd prefer to retain both indexes. I can also remove this line from the example migration in the UPDGRADING.md.
This PR attempts to resolve #217
