+# Unreleased
+- Fix read-predominant auto pong responses not flushing when hitting WouldBlock errors.
+- Improve `FrameHeader::format` write correctness.
+- Up minimum _rustls_ to `0.21.6`.
+- Update _webpki-roots_ to `0.26`.
+
+# 0.20.1
+- Fixes [CVE-2023-43669](https://github.com/snapview/tungstenite-rs/pull/379).
+
+# 0.20.0
+- Remove many implicit flushing behaviours. In general reading and writing messages will no
+ longer flush until calling `flush`. An exception is automatic responses (e.g. pongs)
+ which will continue to be written and flushed when reading and writing.
+ This allows writing a batch of messages and flushing once, improving performance.
+- Add `WebSocket::read`, `write`, `send`, `flush`. Deprecate `read_message`, `write_message`, `write_pending`.
+- Add `FrameSocket::read`, `write`, `send`, `flush`. Remove `read_frame`, `write_frame`, `write_pending`.
+ Note: Previous use of `write_frame` may be replaced with `send`.
+- Add `WebSocketContext::read`, `write`, `flush`. Remove `read_message`, `write_message`, `write_pending`.
+ Note: Previous use of `write_message` may be replaced with `write` + `flush`.
+- Remove `send_queue`, replaced with using the frame write buffer to achieve similar results.
+ * Add `WebSocketConfig::max_write_buffer_size`. Deprecate `max_send_queue`.
+ * Add `Error::WriteBufferFull`. Remove `Error::SendQueueFull`.
+ Note: `WriteBufferFull` returns the message that could not be written as a `Message::Frame`.
+- Add ability to buffer multiple writes before writing to the underlying stream, controlled by
+ `WebSocketConfig::write_buffer_size` (default 128 KiB). Improves batch message write performance.
+- Panic on receiving invalid `WebSocketConfig`.
+
# 0.19.0
