Grafana 1.5.4 released.

Grafana version 1.5.4 has been released, featuring minor enhancements and new functionalities, including a notable update for unsaved changes tracking, which warns users when they attempt to navigate away from a dashboard without saving. The release progress for larger features has been slow due to the developer's commitments to conference talks, such as Monitorama PDX, and limited availability to work on the project, restricted to evenings and weekends. However, from July onwards, the developer plans to dedicate full-time efforts to Grafana, which should accelerate development. Additionally, a live playground and demo site are now available for users to explore.
