Appendix A. Changes since Cowboy 2.14

Prev		Next

The following patch versions were released since Cowboy 2.14:

A.1. Cowboy 2.14.2

Cowboy compiled without COWBOY_QUICER set would have a number of Dialyzer errors. Now in that scenario the HTTP/3 code is fully behind ifdefs and Dialyzer no longer complains.

Now when COWBOY_QUICER isn’t set:

cowboy:start_quic/3 is no longer defined.
cowboy_http3 compiles to an empty module.
cowboy_quicer compiles to an empty module.

A.2. Cowboy 2.14.1

HTTP/2 Websocket did not call terminate/3 on abrupt socket close (without a close frame being sent first). This is now fixed. Do note however that the Websocket session process must trap exits to call terminate/3.
