In this 45 minutes talk Pablo will give an overview of the main features of the Elastic Stack in the last year (e.g. Reindex API, Pipeline Aggregation, and Beats). Pablo will point what you should pay attention to and what you should be careful with. Pablo will also talk about the new features that are coming in 5.0 (e.g. Graph API, Ingest Node, and Logstash Persistency).
