+
+## Serving
+
+**Release notes**: [Knative Serving 1.23](https://github.com/knative/serving/releases/tag/knative-v1.23.0)
+
+This release adds ephemeral volume support, IPv6 networking improvements, and startup probe validation.
+
+**Generic Ephemeral Volumes**
+
+Serving now supports generic ephemeral volumes via `volumeClaimTemplate`, behind the `kubernetes.podspec-volumes-ephemeral` feature flag ([#16590](https://github.com/knative/serving/pull/16590) by [@jbunting](https://github.com/jbunting)). This allows workloads to request dynamically provisioned storage that is tied to the pod lifecycle without needing pre-created PVCs.
+
+**Startup Probe Validation**
+
+Validation has been added for startup probes in user and sidecar containers ([#16594](https://github.com/knative/serving/pull/16594) by [@thiagomedina](https://github.com/thiagomedina)), catching misconfigured probes at admission time rather than at runtime.
+
+**IPv6 Support for Autoscaler**
+
+The autoscaler EndpointSlice creation and activator port replacement now support IPv6 ([#16591](https://github.com/knative/serving/pull/16591) by [@linkvt](https://github.com/linkvt)), extending dual-stack networking support in Serving.
+
+**Bug Fixes**
+
+A fix was made to the ResponseRecorder hijack state tracking for WebSocket connections ([#16611](https://github.com/knative/serving/pull/16611) by [@immanuwell](https://github.com/immanuwell)).
+

+
+#### Apache Kafka Broker
+
+**Release notes**: [Kafka Broker 1.23](https://github.com/knative-extensions/eventing-kafka-broker/releases/tag/knative-v1.23.0)
+
+This release brings improved error handling, security patches, and several data-plane fixes.
+
+**Improved Error Handling**
+
+Error handling has been improved across broker, channel, consumer group, and trigger reconcilers ([#4724](https://github.com/knative-extensions/eventing-kafka-broker/pull/4724) by [@chriscannon](https://github.com/chriscannon)), making it easier to diagnose reconciliation failures.
+
+**Security Updates**
+
+Netty, logback-core, vertx-core, and jackson-core have been updated to resolve known vulnerabilities ([#4744](https://github.com/knative-extensions/eventing-kafka-broker/pull/4744)).
+
+**Bug Fixes**
+
+- The KafkaSink reconciler cluster admin error has been fixed ([#4720](https://github.com/knative-extensions/eventing-kafka-broker/pull/4720) by [@chriscannon](https://github.com/chriscannon))
+- A null check has been added to `ExactFilter` to handle missing `FilterAttributes` ([#4717](https://github.com/knative-extensions/eventing-kafka-broker/pull/4717) by [@Dominic-Stout-GA-i3](https://github.com/Dominic-Stout-GA-i3))

+**Release notes**: [RabbitMQ 1.23](https://github.com/knative-extensions/eventing-rabbitmq/releases/tag/knative-v1.23.0)
+
+This release adds adapter customization and fixes an ingress shutdown race condition.
+
+**Customizable Adapter Container Name**
+
+The RabbitmqSource adapter container name can now be customized ([#1762](https://github.com/knative-extensions/eventing-rabbitmq/pull/1762) by [@vgaidarji](https://github.com/vgaidarji)).
+
+**Ingress Shutdown Race Fix**
+
+A race condition between RabbitMQ connection close and HTTP drain during ingress shutdown has been fixed ([#1760](https://github.com/knative-extensions/eventing-rabbitmq/pull/1760) by [@deadtrickster](https://github.com/deadtrickster)).
+
+---
+
+## Functions
+
+**Release notes**: [Functions 1.23](https://github.com/knative/func/releases/tag/knative-v1.23.0)
+
+A substantial release with new commands, improved builder support, and a growing MCP server.
+
+**New `func logs` Command**
+
+A new `func logs` command streams function logs directly from the CLI ([#3669](https://github.com/knative/func/pull/3669) by [@Itx-Psycho0](https://github.com/Itx-Psycho0)), removing the need to switch to `kubectl` or a dashboard to see what your function is doing.
+
+**Dev Cluster Creation with `func clusters`**
+
+The new `func clusters` command can create local development clusters with Knative pre-installed ([#3754](https://github.com/knative/func/pull/3754) by [@lkingland](https://github.com/lkingland)), making it easier to get a working Knative environment for local development.
+
+**Kafka Event Sourcing for Go Functions**
+
+Go functions can now be scaffolded with Kafka event sourcing support ([#3950](https://github.com/knative/func/pull/3950) by [@aliok](https://github.com/aliok)), providing a ready-made template for consuming Kafka events.
+
+**ImagePullSecret Support**
+
+Functions now support specifying an `ImagePullSecret` ([#3656](https://github.com/knative/func/pull/3656) by [@creydr](https://github.com/creydr)), enabling deployments from private registries that require authentication.
+
+**func-operator Integration**
+
+The deploy command now integrates with the func-operator ([#3657](https://github.com/knative/func/pull/3657) by [@creydr](https://github.com/creydr)), and the deployer choice is now persisted in `func.yaml` with guards against incompatible deployer switches ([#3953](https://github.com/knative/func/pull/3953) by [@gauron99](https://github.com/gauron99)).
+
+**Improved `.funcignore` Support**
+
+`.funcignore` rules are now applied consistently across the host builder ([#3624](https://github.com/knative/func/pull/3624) by [@lkingland](https://github.com/lkingland)) and the OCI builder ([#3789](https://github.com/knative/func/pull/3789) by [@gauron99](https://github.com/gauron99)).
+
+**AWS ECR Credentials Loader**
+
+An AWS ECR credentials loader has been added to Kubernetes keychains ([#3864](https://github.com/knative/func/pull/3864) by [@Nachiket-Roy](https://github.com/Nachiket-Roy)), enabling seamless authentication with ECR registries in cluster builds.
+
+**MCP Server Improvements**
+
+The MCP server received numerous fixes and enhancements, including secret and ConfigMap support for `config_envs_add` ([#3685](https://github.com/knative/func/pull/3685) by [@Ankitsinghsisodya](https://github.com/Ankitsinghsisodya)), split config tools for accurate tool annotations ([#3661](https://github.com/knative/func/pull/3661) by [@Ankitsinghsisodya](https://github.com/Ankitsinghsisodya)), and version info in healthcheck output ([#3745](https://github.com/knative/func/pull/3745) by [@cubaseuser123](https://github.com/cubaseuser123)).
+
+**Security Hardening**
+
+Config files now use secure file permissions ([#3726](https://github.com/knative/func/pull/3726) by [@Itx-Psycho0](https://github.com/Itx-Psycho0)), GitHub webhooks default to TLS verification ([#3714](https://github.com/knative/func/pull/3714) by [@Vi-shub](https://github.com/Vi-shub)), and shell metacharacters are now rejected in prefix validation ([#3760](https://github.com/knative/func/pull/3760) by [@Elvand-Lie](https://github.com/Elvand-Lie)).
+
+**IPv6 and Dual-Stack Support**
+
+Multiple fixes improve IPv6 support: dual-stack `net.Dial` via Happy Eyeballs ([#3692](https://github.com/knative/func/pull/3692)), IPv6 in local Kind cluster setup ([#3693](https://github.com/knative/func/pull/3693)), and listening on IPv6 loopback ([#3817](https://github.com/knative/func/pull/3817)) — all by [@matejvasek](https://github.com/matejvasek).

+
+You can now set a custom host port when creating Kind clusters ([#660](https://github.com/knative-extensions/kn-plugin-quickstart/pull/660) by [@psschwei](https://github.com/psschwei)), making it easier to avoid port conflicts in multi-cluster or shared development environments.
+
+**Improved Startup Reliability**
+
+The plugin now waits for pods to appear before checking readiness ([#669](https://github.com/knative-extensions/kn-plugin-quickstart/pull/669) by [@psschwei](https://github.com/psschwei)), fixing race conditions during cluster setup.
