Announcing Knative 1.11 Release¶

A new version of Knative is now available across multiple components.

Follow the instructions in Installing Knative 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.

Serving¶

Release Notes

🚨 Breaking or Notable¶

Activator uses TLS 1.3 as the minimum version when internal encryption is activated for communication with queue-proxy (#13887, @izabelacg)
Domain mapping controller logic is now merged with the Serving controller. Domainmapping webhook is merged with the Serving webhook. (#14082, @skonto)
DomainMapping/v1alpha1 is deprecated - use v1beta1 APIs (#14058, @dprotaso)

💫 New Features & Changes¶

A new flag is introduced queueproxy.resource-defaults that sets resource requests, limits for Queue Proxy when enabled (applies only to cpu and memory). (#14039, @skonto)
Activator now has a separate service account, reducing its privileges to the required minimum. (#14133, @davidhadas)
Queue proxy resources can be configured via annotations at the service level. The resource percentage annotation is now deprecated. (#14038, @skonto)
Sets DefaultDomain to cluster's domain instead of hardcoded svc.cluster.local (#13964, @kauana)

🐞Bug Fixes¶

Autoscaler metric are validated with global autoscaling class if no class annotation is set. (#13978, @xtreme-vikram-yadav)
Drop cluster-autoscaler.kubernetes.io/safe-to-evict annotations on our control plane to allow nodes to drain (#14035, @dprotaso)
Fix activator load balancing when using unbounded concurrency and when you have two instances of a revision (#14028, @dprotaso)
Queue proxy metrics reporting period is now supported for both prometheus and opencensus. This allows fine-grained control of how often metrics are exported via a new config map attribute. (#14019, @skonto)
Tag to digest min TLS version is 1.2 and can be configured higher using the controller environment variable TAG_TO_DIGEST_TLS_MIN_VERSION and supports values "1.2" and "1.3" (#13962, @dprotaso)
