@AtofStryker I think there's a legitimate failure due to this in our published artifacts. I may have reviewed this too early - sorry if so.

@jennifer-shehane no worries its related to the binary-cleanup. I'll fix it and push it up

this is going to fail semantic pull request because I edited the web-config package. This is expected and I am going to have to ignore the changelog valication until after next release
