While users that +were using Ranch 2.0 already were ready for OTP 24, +the Ranch version used by Cowboy out of the box was +not compatible and had to be updated. + +Cowboy 2.9 also contains a small number of tweaks +and bug fixes. + +Cowboy 2.9 requires Erlang/OTP 22.0 or greater. + +=== Features added + +* Cowboy will now gracefully shutdown HTTP/1.1 and HTTP/2 + connections when the supervisor asks the connection + process to exit, or when `sys:terminate/2,3` is used. + Two new configuration options were added for HTTP/2 + to determine the timeouts for the graceful shutdown + steps. + +* REST handler `AcceptCallback` can now return `{created, URI}` + or `{see_other, URI}` to determine what response status code + should be sent (typically to differentiate between a new + resource and an update). The return value `{true, URI}` is + now deprecated. + +* Update Ranch to 1.8.0. + +* Update Cowlib to 2.11.0. + +=== Bugs fixed + +* Fix concurrent body streaming getting stuck with HTTP/2. + The alarm could get into blocking state indefinitely + when two or more request processes were streaming bodies. + +* Fix HTTP/2 rate limiting using the wrong default values + in some cases. + +* Don't produce an error report when the request process + exited normally (`normal` or `shutdown` exit reasons). + +* Fix `cowboy_tracer_h` to support trace messages without + timestamps. |
