 # Changelog
 
+## 0.8.0
+
+- BREAKING: the prometheus endpoint has changed from port `9108` to `8989` by default
+  - We are now using an internal prometheus endpoint with new metrics
+  - As a result, the `graphiteExporter` sidecar has been removed
+  - Some metrics from the `graphiteExporter` will no longer be present
+  - The parent / main "off-switch" for prometheus is at `prometheus.enabled`
+  - To revert to the old exporter, set `prometheus.legacy=true` (and please reach out to let us know why!)
+
 ## 0.7.6
 
 - Bump Workbench version to 2024.04.2
