This seems to have been done yesterday. Unfortunately, the release bumped only the patch version, and this has broken some dependent crates (e.g. https://github.com/libp2p/rust-libp2p/issues/1654) because async-tls exposes rustls through its public API.
I suggest re-releasing it as 0.8.0. Next time, please, be more considerate about the breaking nature of such changes.
