+### Add configurable histogram buckets per metric ([Issue #4543](https://github.com/apollographql/router/issues/4543))
+
+> [!NOTE]
+>
+> This feature was introduced in v1.40.0 but was prevented from working best until subsequent fixes in later versions.  Therefore, this v1.46.0 release is the first release in which we recommend its use.
+
+The router supports overriding instrument settings for metrics with [OpenTelemetry views](https://opentelemetry.io/docs/concepts/signals/metrics/#views). You can use views to override default histogram buckets.
+
+Configure views with the `views` option. For example:
+
+```yaml
+telemetry:
+  exporters:
+    metrics:
+      common:
+        service_name: apollo-router
+        views:
+          - name: apollo_router_http_request_duration_seconds # Instrument name you want to edit. You can use wildcard in names. If you want to target all instruments just use '*'
+            unit: "ms" # (Optional) override the unit
+            description: "my new description of this metric" # (Optional) override the description
+            aggregation: # (Optional)
+              histogram:
+                buckets: # Override default buckets configured for this histogram
