Kibana 5.0.0-alpha4 has been released, introducing several new features and improvements, including the ability to import CSV data directly into Elasticsearch, enhanced monitoring for Kibana through the X-Pack with tracking capabilities for requests and memory usage, and more flexible visualization options like drag-and-drop sorting of buckets. The release also features a revamped "Management" app, replacing the "Settings" app, which serves as a hub for configuring the Elastic stack and managing users and roles. Although this release is alpha software, intended for testing rather than production use, it paves the way for the upcoming beta release, with developers encouraged to report bugs and provide feedback.
