+- [Thank you contributors](#thank-you-contributors)
+
+## Highlights
+
+There have been various changes in core components for this release.
+
+- For serving we introduced new value `AllowRootBounded` for `secure-pod-defaults` option that balances security with compatibility and is planned to become the default in v1.21 (More info below!).
+- Eventing introduces a complete Request Reply data plane and adds support for Pod default credentials in AWS Integration resources.
+- Functions' CLI now provides more clearer errors and hints to users when things go wrong with build, deploy and delete commands. We also include some bug fixes.
+- Operator recieved a fix for deadlock occurring during KnativeServing creation with `system-internal-tls` enabled.
+
+## Serving
+
+**Original notes**: [Knative Serving 1.20](https://github.com/knative/serving/releases/tag/knative-v1.20.0)
+
+### 🚨 Breaking or Notable Changes
+
+- In v1.19 we've dropped support for OpenCensus (which has been deprecated for a while) in favour of OpenTelemetry. This is a breaking change and details are documented here in the [design document](https://docs.google.com/document/d/1QQ_ubc0RjeZbRHdN4rQR85Z7RZfTSjz4GoKsE0dZ2Z0/edit?pli=1&tab=t.0#heading=h.n8a530nnrb=). and the website (https://knative.dev/docs/serving/observability/metrics/collecting-metrics/)
+- Secure Pod Defaults  ([#16042](https://github.com/knative/serving/16042), [@nader-ziada](https://github.com/nader-ziada))
+- We've introduced `secure-pod-defaults` in an earlier release but this release includes a new setting `AllowRootBounded` that offers a better security posture for your workloads
+but balances the compatibility with images that require/expect you to run as root.
+For `v1.20` release the `secure-pod-defaults` default will remain `disabled` but in a future release (most likely `v1.21`) we will switch this default to `AllowRootBounded`.
+
+### 💫 New Features & Changes
+
+- Create a new value for `secure-pod-defaults`: `AllowRootBounded` when AllowRootBounded,
+defaults SeccompProfile and Capabilities if nil and when enabled sets RunAsNonRoot
+to true if not already specified ([#16042](https://github.com/knative/serving/pull/16042), [@nader-ziada](https://github.com/nader-ziada))
