Grafana version 5.1 builds on its major 5.0 release with enhancements aimed at refining the user experience and adding new features, such as heatmap support for Prometheus and a core data source for Microsoft SQL Server. The update also includes a revamp of the Grafana Docker container, introducing a breaking change in file permissions that affects existing containers, alongside improvements to scrolling and dashboard panel management, such as copy-paste functionality. The release enhances Prometheus integration by allowing histogram transformation into heatmaps and adds autocomplete for template variables in the query editor. Additionally, the Microsoft SQL Server plugin now enables users to query and visualize data from SQL Server databases, including Azure SQL Database, and set alert rules. Other updates include alignment of zero-lines on graph panels, table panel enhancements, new variable interpolation syntax, and improved workflows for provisioned dashboards, with detailed updates provided in the changelog.
