 ## v2.6.0 to v2.6.1
 
+### Metrics
+
 In `v2.6.1`, the metrics system does not support any more custom HTTP method verbs to prevent potential metrics cardinality overhead.
 In consequence, for metrics having the method label,
 if the HTTP method verb of a request is not one defined in the set of common methods for [`HTTP/1.1`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods)
 or the [`PRI`](https://datatracker.ietf.org/doc/html/rfc7540#section-11.6) verb (for `HTTP/2`),
 the value for the method label becomes `EXTENSION_METHOD`, instead of the request's one.
+
+### Tracing
+
+In `v2.6.1`, the Datadog tags added to a span changed from `service.name` to `traefik.service.name` and from `router.name` to `traefik.router.name`.
