@colindean Your correct, patch releases are for very special circumstances.
I don't believe you have any option except to build this yourself until 1.9.0
gets released; and since 1.8.0 just came out, that is going to be a bit.
To keep things stable, you can checkout the 1.8.0 tag and apply your change
as a cherry pick so you don't accidentally include any unexpected changes, but
still an internal build.---
