What’s New in Loki v0.4.0

Loki v0.4.0 introduces several new features and improvements as the project progresses towards its first GA release. One significant update is the ability to calculate metrics from logs using a Prometheus-compatible API, allowing users to create metric panels and dashboards in Grafana by setting up a Prometheus datasource pointing to Loki. Active development is underway to enable these metric-style queries directly against a Loki datasource in Grafana. The release also includes enhancements to the Loki documentation, with new sections on configuration and the HTTP API, and introduces new /loki/api/v1/* endpoints to replace deprecated ones, aiming for Prometheus compatibility and improved API structure. With nearly 150 pull requests included, the release sees significant contributions, and while performance and stability are strong, the focus is now on refining the roadmap and prioritizing future features as Loki approaches its v1.0.0 milestone.
