+### 🛑 Breaking changes 🛑
+
+- `auto-instrumentation`: Update recommended resource attributes to match the [semantic conventions](https://github.com/open-telemetry/semantic-conventions/blob/main/docs/non-normative/k8s-attributes.md) (#3797)
+  This change updates the recommended resource attributes to match the [semantic conventions](https://github.com/open-telemetry/semantic-conventions/blob/main/docs/non-normative/k8s-attributes.md).
+  The following attributes have been updated:
+  - `service.version` now uses the docker image digest in addition to the tag
+  - the well-known label `app.kubernetes.io/part-of` for `service.namespace` has been removed
+  - the well-known label `app.kubernetes.io/instance` has been added (translates to `service.name`)
+  - `service.namespace` now also uses the Kubernetes namespace name (if `resource.opentelemetry.io/service.namespace` is not set)
+  
+  **You can do the following to avoid breaking changes**:
+  - `service.version`: Set the version explicitly using `resource.opentelemetry.io/service.version` 
+    (not recommended, the version has only been made more specific)
+  - `service.namespace`: Set the namespace explicitly using `resource.opentelemetry.io/service.namespace` - 
+    or just rely on the Kubernetes namespace name, which is now the default
+  - `service.name`: If you have enabled `useLabelsForResourceAttributes`:
+    Set the name explicitly using `resource.opentelemetry.io/service.name` if `app.kubernetes.io/instance` is used for another purpose 
+  
+
+### 💡 Enhancements 💡
+
+- `target allocator`: Specific changes on CRD, Manifest, Controller, etc to allow specifying value for collector grace period (#3781)
+- `auto-instrumentation`: Increase default instrumentation memory limit to 256Mi (#3479)
+
+### 🧰 Bug fixes 🧰
+
+- `collector`: Fix the default configuration for the internal metrics endpoint (#3730)
+- `collector`: Set the default endpoint to 0.0.0.0:13133 for the collector health check extension (#3825, #3688)
