Logstash 7.4.0 has been released, marking the general availability of the pipeline-to-pipeline communication feature, which enhances the modularity and performance of processing by enabling the connection of multiple pipelines within a single Logstash instance while maintaining at-least-once delivery semantics. This feature supports complex processing scenarios, such as segregating processing logic for various data types from a single input or improving delivery reliability across multiple outputs. Additionally, the Logstash NetFlow module has been deprecated in favor of the Filebeat NetFlow module, which aligns with the Elastic Common Schema and offers seamless integration with the Elastic SIEM application. Users are encouraged to download the new release, explore its features, and provide feedback through Elastic's social media channels or forums.
