on GitHub

🚨 Breaking or Notable

• In v1.2.0 we introduced an experimental field RevisionSpec.MaxDurationSeconds in error. It has been removed in this release. (#12634, @dprotaso)
• Our minimum K8s version is now 1.21 (#12509, @dprotaso)
• PodDisruptionBudget updated to v1 API (#12548, @psschwei)

💫 New Features & Changes

• Improves the error message when a DomainMapping cannot be reconciled because autocreate-cluster-domain-claims is false and the CDC does not exist. (#12439, @julz)
• Utilizes Kubernetes's immediate trigger of readiness probes after startup, restores default periodSeconds for readiness probe to Kuberentes default (10s) (#12550, @psschwei)

🐞 Bug Fixes

• Ensure the activator drains properly and the autoscaler rolls out conservatively. This helps avoid hitting 503s during upgrade. (#12621, @dprotaso)
• Fixes an activator panic when the throttle encounters a cache.DeleteFinalStateUnknown (#12680, @dprotaso)
• Remove an unnecessary start delay when resolving tag to digests (#12669, #12761, @dprotaso)
• Controllers now properly shut down and relinquish their K8s leases. This fixes potential dropped traffic during upgrades. (knative/pkg#2436, @dprotaso)
• Bump google/go-containerregistry which includes various fixes tag to digest when looking up registry credentials (#12510, @dprotaso)
• Fix an activator crash that could disrupt traffic (503) (#12676, @dprotaso)
• Changes liveness probes to directly probe the user container rather than queue proxy. (#12479, @julz)

🧪 Experimental

• PVC support behind the feature flags kubernetes.podspec-persistent-volume-claim kubernetes.podspec-persistent-volume-write (#12458, @skonto)
