Numerous options have been added to control -SETTINGS and related behavior. In addition experimental -support for Websocket over HTTP/2 was added. - -=== Features added - -* Add experimental support for Websocket over HTTP/2. - You can use the `enable_connect_protocol` option to - enable. It implements the following draft: - https://tools.ietf.org/html/draft-ietf-httpbis-h2-websockets-01 - -* Add options `max_decode_table_size` and - `max_encode_table_size` to restrict the size of the - HPACK compression dictionary. - -* Add option `max_concurrent_streams` to restrict the - number of HTTP/2 streams that can be opened concurrently. - -* Add options `initial_connection_window_size` and - `initial_stream_window_size` to restrict the size of - the HTTP/2 request body buffers for the whole connection - and per stream, respectively. - -* Add options `max_frame_size_received` and - `max_frame_size_sent` to restrict the size of - HTTP/2 frames. - -* Add option `settings_timeout` to reject clients that - did not send a SETTINGS ack. Note that this currently - may only occur at the beginning of the connection. - -* Update Ranch to 1.5.0 - -* Update Cowlib to 2.3.0 - -=== Bugs fixed - -* Fix the END_STREAM flag for informational responses - when using HTTP/2. - -* Receive and ignore HTTP/2 request trailers if any - for HTTP/2 requests. Request trailer information will - be propagated to the user code in a future release. - -* Reject WINDOW_UPDATE frames that are sent after the - client sent an RST_STREAM. Note that Cowboy will not - keep state information about terminated streams - forever and so the behavior might differ depending - on when the stream was reset. - -* Reject streams that depend on themselves. Note that - Cowboy currently does not implement HTTP/2's priority - mechanisms so this issue was harmless. - -* Reject HTTP/2 requests where the body size is different - than the content-length value. Note that due to how Cowboy - works some requests might go through regardless, for - example when the user code does not read the request body. - -* Fix all existing test failures from RFC7540. This was - mostly incorrect test cases or intermittent failures. |
