Grafana version 1.5.4 has been released, featuring small new enhancements and a significant update that introduces unsaved changes tracking, alerting users when navigating away from a dashboard without saving. The release notes mention a slow progression of larger features due to pending pull requests and the developer's limited availability, as Torkel Ödegaard is preparing for conference talks and currently dedicates only evenings and weekends to Grafana. However, a shift is anticipated from July onwards, as Ödegaard plans to work on Grafana full-time, which is expected to accelerate development. Additionally, there is now a live playground and demo site available for users to explore.
