### 🚨 Breaking or Notable

### 💫 New Features & Changes

- Added an autoscaling annotation to choose a different aggregation algorithm for the autoscaling metrics. This is experimental currently. ([#10840](https://github.com/knative/serving/pull/10840), [@vagababov](https://github.com/vagababov))
- Added `autocreateClusterDomainClaims` flag to network config map. ([networking#330](https://github.com/knative/networking/pull/330), [@julz](https://github.com/julz))

### 🐞 Bug Fixes

- Adds validation that a default max-scale is set if a max-scale-limit is specified in the autoscaler configmap (since otherwise the default max-scale, i.e. 0 = no max, would fail validation as it is above the max-scale-limit). ([#10921](https://github.com/knative/serving/pull/10921), [@julz](https://github.com/julz))
- Bumped the resource request and limits of the autoscaler to 100m/100Mi, 1000m/1000Mi respectively. ([#10865](https://github.com/knative/serving/pull/10865), [@markusthoemmes](https://github.com/markusthoemmes))
- Fixed a regression where the pod bringup time might have a latency of 10s or more even though the container should be up quickly. ([#10992](https://github.com/knative/serving/pull/10992), [@markusthoemmes](https://github.com/markusthoemmes))
- Reduced the necessary memory allocations in the activator significantly, especially with disabled tracing. ([#11016](https://github.com/knative/serving/pull/11016), [#11013](https://github.com/knative/serving/pull/11013), [#11009](https://github.com/knative/serving/pull/11009), [#11008](https://github.com/knative/serving/pull/11008), [@markusthoemmes](https://github.com/markusthoemmes))
- Fix the incorrect Gateway name format for DomainMapping auto TLS feature for net-istio implmenetation. ([net-istio#532](https://github.com/knative-sandbox/net-istio/pull/532), [@ZhiminXiang](https://github.com/ZhiminXiang))
