Kibana 4.5.0 has been released, featuring new updates that align with the latest advancements in Elasticsearch, requiring at least version 2.3.0. The release, which is relatively smaller as the team focuses on preparing Kibana 5.0, includes enhancements such as the ability to assign labels to metric aggregations, automatic clearing of errors after five minutes, customizable display of saved objects, and the listing of installed plugins via the command line interface. Bug fixes address issues like pre-flight request errors, improper handling of legend values with special characters, and usability improvements in areas such as area chart highlighting, color palette usage, and timeouts in Elasticsearch communication. This version is available on Elastic Cloud and for download, promising users a more stable and efficient experience.
