It would seem, after cargo publish
did its work, crates.io is updated to vsn 0.3.8 ( https://crates.io/crates/rustfbp ) whereas GitHub - rust-lang/crates.io-index: Registry index for crates.io is not updated ( crates.io-index/rustfbp at master · rust-lang/crates.io-index · GitHub )
Is there something wrong with the plumbing?
