# 0.3.9 (December 9, 2021)

* Fix hang related to new `max_send_buffer_size`.

# 0.3.8 (December 8, 2021)

* Add "extended CONNECT support". Adds `h2::ext::Protocol`, which is used for request and response extensions to connect new protocols over an HTTP/2 stream.
* Add `max_send_buffer_size` options to client and server builders, and a default of ~400MB. This acts like a high-water mark for the `poll_capacity()` method.

# 0.3.7 (October 22, 2021)

* Fix panic if server sends a malformed frame on a stream client was about to open.

* Fix sending of very large headers. Previously when a single header was too big to fit in a single `HEADERS` frame, an error was returned. Now it is broken up and sent correctly.
* Fix buffered data field to be a bigger integer size.

# 0.3.4 (August 20, 2021)

* Fix panic when encoding header size update over a certain size.
* Fix `SendRequest` to wake up connection when dropped.

* Fix stream ref count when sending a push promise
* Fix receiving empty DATA frames in response to a HEAD request
* Fix handling of client disabling SERVER_PUSH

# 0.2.6 (July 13, 2020)

# 0.1.25 (June 28, 2019)

* Fix to send a `RST_STREAM` instead of `GOAWAY` if receiving a frame on a previously closed stream.
