==== Multicast Discovery is now a plugin
Support for multicast is very patchy. Linux doesn’t allow multicast listening on localhost,
while OS/X sends multicast broadcasts across all interfaces regardless of the configured
bind address. On top of that, some networks have multicast disabled by default.
This feature has been moved to a plugin. The default discovery mechanism now uses
unicast, with a default setup which looks for the first 5 ports on localhost. If you
still need to use multicast discovery, you can install the plugin with:
[source,sh]
------------------
./bin/plugin install discovery-multicast
------------------
See {plugins}/discovery-multicast.html for more information.
