Grafana version 1.8.0-rc1 introduces a range of significant updates, marking it as one of the most substantial releases since its inception. Key enhancements include a revamped templating system, improved Graphite and InfluxDB query editors, and various UI upgrades, such as the removal of modals and enhanced search functionalities with colored tags. The release also supports mixed graph styling, allowing for customizable display settings, and introduces some breaking changes for InfluxDB users that require query updates. Despite ongoing improvements, documentation for these new features is still in development, with current details available through this blog post and demo dashboards. Developer Torkel Ödegaard, who is supported by sponsors like Squarespace and Dreamhost, encourages users to contribute financially to support ongoing development and announces an upcoming Grafana and InfluxDB meetup in New York.
