- Backported the Event get/set API. These changes enable Logstash 2.4 to install plugins that use the 5.0 API (Issue 5449).
Added support for writing Logstash’s logs in JSON format. You can use the command-line flag
--log-in-jsonto specify that Logstash write its own logs in JSON (Issue 1569).
Plugin Generator: Added a subcommand
bin/logstash-plugin. This bootstraps a new plugin with the correct directory structure and all the required files (templates).
- Beats input has been reimplemented using Netty, an asynchronous IO framework for Java. This rewrite for performance brings the plugin in line with the Logstash Forwarder + LS combination (Issue 92).
