+## Upcoming release
+
+### Changed
+
+- The implementation of `AsyncTls` for `tokio_native_tls::TlsAcceptor` now requires the connection type to implement `Send`. This in turn allows `TlsListener` to be `Send` when using the `native-tls` feature. Technically, this is a breaking change. However, in practice it is unlikely to break existing code and makes using `TlsListener` much easier to use when `native-tls` is enabled.

 NOTE: This release contains several breaking changes.
