Config File Cannot Work on Logstash 2.3

Elastic Stack Logstash

Is there any information on how config file written for logstash 2.2 should be modified in order to be used on logstash 2.3.x?

All my config fails to work. Nothing runs.

All I get is this

JAVA_OPTS was set to [ -XX:HeapDumpPath="$LS_HOME/heapdump.hprof"]. Logstash will trust these options, and not set any defaults that it might usually set
io/console not supported; tty will not be manipulated
Settings: Default pipeline workers: 4
Pipeline main started

Have you looked in the release notes?

This message indicates that Logstash started up just fine. What makes you say that it isn't working?
