🚨 Breaking or Notable

1. Fixes for K8s 1.22

Related issue: #11448

Our webhook parser no longer rejects unknown fields in an object's metadata. New fields were introduced in K8s 1.22 which caused Knative's webhook to reject certain operations.

2. Renaming of some net-kourier components

Related issue: knative/networking#448

As part of our efforts to GA/1.0 we've standardized on the naming of our networking plugins that are installed along side Serving. If you're managing your Knative deployment manually with kubectl this will require a two-phase upgrade process. In order to upgrade net-kourier to v0.25.0 using kubectl please follow the steps:

# Apply the new release
$ kubectl apply -f net-kourier.yaml

# Once the deployment is ready apply the same file but 
# prune the old resources
$ kubectl apply -f net-kourier.yaml \
  --prune -l networking.knative.dev/ingress-provider=kourier

3. Disabling namespace certificate provisioning legacy label

The namespace label networking.internal.knative.dev/disableWildcardCert has been deprecated since v0.15.0 release in favour of networking.knative.dev/disableWildcardCert. We have dropped support for this legacy label. (#11626, @nak3)
