Caused by lukeed/mrmime#8

[stalkerg]

@benmccann I tried to update mrmime manually and it didn't help. Anyway, thanks.

[lukeed]

released mrmime@2.0.0 w/ the updated values. because MIME value(s) changed, marked this release as breaking

[benmccann]

Thanks @lukeed. We'll need sirv to use the latest version of mrmime, so I just sent you a PR for that: lukeed/sirv#156

[stalkerg]

Thanks, @benmccann and @lukeed !!!
