  - Update the plugin to the version 2.0 of the plugin api, this change is required for Logstash 5.0 compatibility. See https://github.com/elastic/logstash/issues/5141
# 2.0.4
  - Depend on logstash-core-plugin-api instead of logstash-core, removing the need to mass update plugins on major releases of logstash

  - New dependency requirements for logstash-core for the 5.0 release
