Btw - iirc this email address has already been bouncing for me when replying to v1 patches. Interestingly enough you did Cc the cover letter to Connor Davis <connojda...@gmail.com> (which I'm using in replacement for the other address in this reply). And I can only assume that the address did bounce for you as well when sending both v1 and v2 ... Jan
