Grafana 7.5 introduces several notable enhancements, including the new pie chart panel, which is now a fully integrated visualization option, and alerting support for Loki, allowing users to create alerts on Loki metric queries. The release also features a more user-friendly Logs browser for navigating Loki labels, and Grafana Tempo has been added as a backend data source for improved trace data handling. Elasticsearch users benefit from word highlighting in log searches, and PostgreSQL setup is simplified by allowing SSL certificates to be pasted directly into the UI. Cloudwatch data source improvements include support for additional AWS metrics, region-specific enhancements, and configuration options to reduce latency. Grafana Enterprise users gain query caching for faster dashboard loads and support for template variables in reports, while active user limits are enforced based on license terms. The update encourages users to explore these features through detailed documentation, changelogs, and available webinars, emphasizing community contributions in the development process.
