+
+### Changed
+
+- Prometheus exporter is now bound to 0.0.0.0 instead of localhost
+- `PROMETHEUS_EXPORTER_HOST` and `PROMETHEUS_EXPORTER_PORT` env vars were added to the `docker-compose.yml` file to allow you to set the host and port for the Prometheus exporter. They should be added to both `dawarich_app` and `dawarich_sidekiq` services Example:
+
+```diff
+  dawarich_app:
+    image: freikin/dawarich:latest
+    container_name: dawarich_app
+    environment:
+      ...
+      PROMETHEUS_EXPORTER_ENABLED: "true"
++     PROMETHEUS_EXPORTER_HOST: 0.0.0.0
++     PROMETHEUS_EXPORTER_PORT: "9394"

+  dawarich_sidekiq:
