Grafana 7.3 introduces significant enhancements, including the integration of Grafana Tempo, an open-source distributed tracing system that complements the existing Grafana observability suite. This release brings new features such as standardized color palettes for visualizations, improved table panel options, and community-driven enhancements like short links and CSV exports for Excel. It also provides advanced functionalities for Grafana Enterprise users, such as data source usage insights and audit logging, and introduces Sigv4 authentication for AWS Elasticsearch users. Additionally, the version supports multiple pipeline aggregations in Elasticsearch, plugin signing to ensure code verification, and a live update feature for real-time dashboard changes. These updates aim to enhance user experience, improve data visualization, and expand Grafana's capabilities as a comprehensive observability platform.
