# 0.17.2
- Make `Origin` header case-sensitive (to keep compatibility with poorely-written servers that don't accept lowercase `Origin` header).
- Make semantics of the reading form the `WebSocketStream` more reasonable (return `None` instead of an error when the stream is normally closed).
- Imrpove the way `poll_close()` works by properly driving the close of the stream till completion.
# 0.17.1
- Update the `tungstenite` dependency (fixes a panic in `tungstenite` and MSRV), see [`tungstenite`'s changelog for more details](https://github.com/snapview/tungstenite-rs/blob/master/CHANGELOG.md#0172).
# 0.17.0
- Update the dependencies, please refer to the [`tungstenite` changelog](https://github.com/snapview/tungstenite-rs/blob/master/CHANGELOG.md#0170) for the actual changes.
# 0.16.1
- Fix feature selection problem when using TLS.
# 0.16.0
- Add a function to allow to specify the TLS connector when using `connect()` like logic.
- Add support for choosing the right root certificates for the TLS.
- Change the behavior of the `connect()` so that it fails when using TLS without TLS feature.
- Do not project with Unpin.
- Update the dependencies with important [implications / improvements](https://github.com/snapview/tungstenite-rs/blob/master/CHANGELOG.md#0160).
# 0.15.0
- Update the `tungstenite-rs` version to `0.14.0`,
[check `tungstenite-rs` release for more details](https://github.com/snapview/tungstenite-rs/blob/master/CHANGELOG.md#0140).
# 0.14.0
- Support for `rustls` as TLS backend.
- The `tls` feature was renamed to `native-tls` and uses a OS-native TLS implementation.
- A new `native-tls-vendored` feature that uses `native-tls` but forces to build a vendored
version (mostly for `openssl`) instead of linking against the system installation.
- New `rustls-tls` feature flag to enable TLS with `rustls` as backend.
- `stream::Stream` was renamed to `MaybeTlsStream` and wraps a `rustls` TLS stream as well now.
- If both `native-tls` and `rustls-tls` are enabled `native-tls` is used by default.
- A new `Connector` was introduced that is similar to the previous `TlsConnector` but now allows
to control the used TLS backend explicitly (or disable it) in `client_async_tls_with_config`.
# 0.13.0
- Upgrade from Tokio 0.3 to Tokio 1.0.0.
