• New: Introduce the prometheus elasticsearch exporter.

  The elasticsearch exporter allows monitoring Elasticsearch clusters with Prometheus.

dunst⚑

• New: Introduce dunst.

  Dunst is a lightweight replacement for the notification daemons provided by most desktop environments. It’s very customizable, isn’t dependent on any toolkits, and therefore fits into those window manager centric setups we all love to customize to perfection.
