+# Announcing Knative 1.8 Release
+
+A new version of Knative is now available across multiple components.
+
+Follow the instructions in [Installing Knative](https://knative.dev/docs/install/) to install the components you require.
+
+This release brings a number of smaller improvements to the core Knative Serving and Eventing components, and several improvements to specific plugins.

+
+## General
+
+### 🚨 Breaking or Notable
+
+* Our macOS binaries have been notarized so you should be able to run them right away when downloading them from GitHub without having to change Gatekeeper settings.
+
+### 💫 New Release
+
+* [Security-Guard Alpha](https://github.com/knative-sandbox/security-guard/releases/tag/v0.2.0) is now released to allow cyber monitoring and control of knative services.
+
+## Serving
+
+[Release Notes](https://github.com/knative/serving/releases/tag/knative-v1.8.0)
+
+### 🚨 Breaking or Notable
+
+- Uses the cluster domain suffix `svc.cluster.local` as the default domain. As routes using the cluster domain suffix are not exposed through Ingress, users will need to [configure DNS](https://knative.dev/docs/install/yaml-install/serving/install-serving-with-yaml/#configure-dns) in order to expose their services (most users probably already are). ((#13259, @psschwei)
+- Upgrade HorizontalPodAutoscaler to autoscaling/v2 API version (#13337, @nader-ziada)
+- Services may now set `seccompProfile` in SecurityContext to allow users to comply with the `restricted` Pod Security Standards best-practice (#13401, @evankanderson)
+- Bump min-version to k8s 1.23, so removing kind 1.22 testing (#13357, @nader-ziada)
+- Increase the outbound context deadline in reconcilers to 30s (from 10s) to match the maximum K8s webhook timeout. (#13323, @mattmoor)
+
+### 💫 New Features & Changes
+
+- Add timeout handling in Activator  when processing a request for a revision (#13261, @nader-ziada)
+- EmptyDir volumes feature flag is now enabled by default (#13405, @dprotaso)
+- Queue proxy explicit set `SeccompProfile` to `RunTimeDefault` to be able to run under restricted PSP policy by default. (#13376, @skonto)
+- Save data from perf tests to create a dashboard. (#13192, @nader-ziada)
+
+### 🐞Bug Fixes
+
+- Knative services can now specify securityContext.allowPrivilegeEscalation (#13395, @mattmoor)
+- ConfigMap config-defaults property `revision-response-start-timeout-seconds` now defaults to `revision-timeout-seconds`. This should unblock upgrades who set `revision-timeout-seconds` lower than the default value of 300 (#13255, @dprotaso)
+- Fix LatestReadyRevision semantics so it only advances forward. When a Revision fails the Configuration & Route will no longer fall back to older revision. The exception is when you rollback to a Revision that is explicitly named. (#13239, @dprotaso)
+
+## Eventing
+
+[Release Notes](https://github.com/knative/eventing/releases/tag/knative-v1.8.0)
+
+### 🚨 Breaking or Notable
+
+* The HorizontalPodAutoscaler manifests have been updated to v2, which is available with k8s 1.23+ (#6549, @matzew)
+* Add readiness and liveness probes in Knative Eventing controller (#6566, @lionelvillard)
+* Update k8s library to 1.25.2 (#6561, @lionelvillard)
+* Update pelletier/go-toml/v2 to v2.0.5 (#6574, @dsimansk)
+
+### 💫 New Features & Changes
+
+* InMemoryChannel receiver validates received events (#6511, @pierDipi)
+
+### 🐞Bug Fixes
+
+* Fixing PodSecurity Policy warnings for restricted environments (#6533, @matzew)
+* Remove check for v1 API of ConfigMap as there is only v1 CMs (#6502, @matzew)
+* Fixes issue with sugar controller always setting the broker class to MTChannelBasedBroker instead of using the defaults ConfigMap (#6500, @gab-satchi)
+* Port old e2e containersource test to reconciler test (#6507, @liuchangyan)
+* Remove strict check in scorer plugins and respect max skew parameter. Requeue request when no pods available rather than fail scheduler. (#6524, @aavarghese)
+
+## Client
+
+[Release Notes](https://github.com/knative/client/releases/tag/knative-v1.8.0)
+
+#### 💫 New Features & Changes
+
+* Add `--scale-activation` flag to `service create` command options (#1729, @vyasgun)
+* Provide cli options to enable Kubernetes user, uid, and group impersonation via `--as`, `--as-group` and `--as-uid` flags (#1745, @a7i)
+
+### Bug or Regression
+
+* Fix release script version calculation (#1737, @dsimansk)
+
+

+
+[Release Notes](https://github.com/knative/func/releases/tag/knative-v1.8.0)
+
+#### 💫 New Features & Changes

+* Support deployments/workloads probe overrides (#1247, thanks @skonto)
