+## 🛑 Breaking changes 🛑
+- `elasticsearchreceiver`: Remove direction for metrics. The feature gate: receiver.elasticsearchreceiver.emitMetricsWithoutDirectionAttribute can be set to apply the following (#13258) (#12189)
+  - `elasticsearch` metrics:
+    - `elasticsearch.node.cluster.io` will become:
+      - `elasticsearch.node.cluster.io.received`
+      - `elasticsearch.node.cluster.io.sent`
+- `kubeletstatsreceiver`: Remove direction for metrics. The feature gate: receiver.kubeletstatsreceiver.emitMetricsWithoutDirectionAttribute can be set to apply the following (#12588) (#12164)
+  - `kubeletstats` metrics:
+    - `k8s.node.network.io` will become:
+      - `k8s.node.network.io.transmit`
+      - `k8s.node.network.io.receive`
+    - `k8s.node.network.errors` will become:
+      - `k8s.node.network.errors.transmit`
+      - `k8s.node.network.errors.receive`
+- `processor/metricstransform`: Remove `processor.metricstransformprocessor.UseOTLPDataModel` feature flag. OpenCensus-based implementation is not available anymore.
+ (#13405)
+- `exporter/mezmoexporter`: This change removes the hardcoded "otel" hostname that was embedded
+in outgoing logs data.
+ (#13410)
+  It is replaced by:
+  
+    1. Sending to a new collector endpoint that does not require the
+    hostname parameter.
+  
+    2. Recognizing the "host.name" resource attribute and using that
+    value to fill in log metadata recognized upstream.
+  
+    This is a breaking change, and as such will generate a startup
+    error if the exporter is configured to send to an endpoint that
+    does not support this feature.
+- ``filelog`, `journald`, `otlpjsonfile`, `syslog`, `tcplog`, `udplog`, `windowseventlog` receivers`: Remove `helper.Duration` struct. Configured time values no longer have a default unit of `s` (#13439)
