Kubernetes 1.36.3

• Fixes a kubelet memory leak in Kubernetes 1.36. The leak came from contexts that stayed open on every Pod sync.
• Fixes a server-side apply regression. A patch of a container list or map could return 422 required for requests that previously succeeded.
• Fixes DRA scheduling so shared device counters stay accurate when the allocator rejects or backtracks a candidate.

Cilium 1.19.6

• Fixes a regression that could drop established connections for a short time while the Cilium agent restores network policy after a restart
• Removes stale host-port entries when a host-network Pod is deleted and created again immediately
• Keeps remote backends when ClusterMesh service affinity is set to none and the Service has no local endpoints

See the v1.19.6 release notes.

• Supports loadBalancerSourceRanges on load balancer Services

See the v0.14.1 release notes.
