This version is a -very good milestone toward that goal and most of everything -should now work. Release upgrades and a few details will -be improved in future versions. - -=== Features added - -* Add support for all functions from the module `sys`. Note - that Cowboy currently does not implement the `sys` debugging - mechanisms as tracing is recommended instead. - -* Add a `max_frame_size` option for Websocket handlers - to close the connection when the client attempts to - send a frame that's too large. It currently defaults - to `infinity` to avoid breaking existing code but will - be changed in a future version. - -* Update Cowlib to 2.2.1. - -* Add support for the 308 status code and a test suite - for RFC7538 where it is defined. - -=== Bugs fixed - -* Ensure timeout options accept the value `infinity` as - documented. - -* Properly reject HTTP/2 requests with an invalid content-length - header instead of simply crashing. - -* When switching from HTTP/1.1 to Websocket or user protocols - all the messages in the mailbox were flushed. Only messages - specific to `cowboy_http` should now be flushed. - -* Parsing of the x-forwarded-for header has been corrected. - It now supports IPv6 addresses both with and without port. - -* Websocket subprotocol tokens are now parsed in a case - insensitive manner, according to the spec. - -* Cookies without values are now allowed. For example `Cookie: foo`. - -* Colons are now allowed within path segments in routes provided - to `cowboy_router:compile/1` as long as they are not the first - character of the path segment. - -* The `cowboy_req:delete_resp_header/2` function will no longer - crash when no response header was set before calling it. - -* A miscount of the output HTTP/2 flow control window has been - fixed. It prevented sending the response body fully to some - clients. The issue only affected response bodies sent as iolists. |
