Grafana 6.4 introduces an array of new features and improvements aimed at enhancing data models and query execution for more robust analytics and streaming capabilities, setting the stage for future developments. Key features include the ability to share query results between panels, a new logs panel that supports data sources like Elastic and Loki, and live tailing improvements allowing users to pause log streams. The update also brings enhancements to data links, enabling dynamic linking to other dashboards and systems, and introduces a series override feature for graph panels. Grafana's Docker image is now based on Alpine 3.10, ensuring better security, while PhantomJS is deprecated in favor of the Grafana Image Renderer plugin. Enterprise users gain new reporting capabilities, allowing the generation and scheduling of PDF reports of dashboards, and GitLab OAuth now supports Team Sync for synchronizing GitLab Groups with Grafana Teams. Additionally, Grafana-toolkit, a CLI for plugin developers, is in alpha and aims to simplify plugin development, and an LDAP Debug UI has been introduced to improve the setup and testing of LDAP integrations.
