Thank you @d47081 for contributing to this repo.

WS_LISTEN has been renamed to WS_ADDRESS.

See https://github.com/ratchetphp/Ratchet/blob/master/src/Ratchet/Server/IoServer.php#L57

Keep it up,

@programarivm and thanks to you for this amazing product!

Just imo it's better to call it LISTEN because option related to interface where connections coming from and ADDRESS is the mostly common definition and can have many of interpretations

It's also more clear for linux administrators by netstat -tulpn | grep LISTEN

Anyway, would be nice to explain config file with comments as I've played lot of time before launched the instance.

upd.

okay, if that's more native for library users - I'll update the docs drafted for this change.
