knative/serving knative-v1.4.0

Knative Serving release v1.4.0

on GitHub

🚨 Breaking or Notable

• Our minimum supported Kubernetes version is now 1.22 (#12753, @dprotaso)
• When using the Horizontal Pod Autoscaler (HPA), revisions will only be marked as ready after the initial-scale / min-scale value is reached. For example, if min-scale: "4", the revision will not be marked ready until all four pods are ready. Note that revisions may take slightly longer to become ready after this change. See https://knative.dev/docs/serving/autoscaling/scale-bounds/ for more details. (#12811, @psschwei)

💫 New Features & Changes

• serving.knative.dev/release labels, deprecated in v1.3, have been removed. Please switch over to using app.kubernetes.io/name: knative-serving and app.kubernetes.io/version: $VERSION. (#12754, @psschwei)
• Users can configure a per-revision progress deadline by setting the serving.knative.dev/progress-deadline annotation in .spec.template.metadata.annotations (#12751, @psschwei)
