## Why v0.2.2's config-hash rolling restart exposed a latent non-determinism: `client.List` returns cache-ordered results, so the resolver's forward zones reshuffled every reconcile, flipping the config hash and rolling `bind-resolvers-2` endlessly. v0.2.3 (bind-operator #11) sorts every rendered list so `named.conf` is byte-identical across reconciles and the hash is stable. ## Changes - Bump the operator image (`bind-system/deployment.yaml`) and the pulled CRD bundle URL (`bind-system/kustomization.yaml`) to `v0.2.3`. - Bump the `bind-tsig-api` image (`bind-internal/tsig-api/tsig-api.yaml`) to `v0.2.3`. CRDs are unchanged from v0.2.2 (controller-only change), so the generated kubeconform schemas need no update. ## Validation - `bind-system` renders with the v0.2.3 CRD bundle; `bind-internal` passes `kubeconform` (56/56); pre-commit clean. ## Deploy note On deploy the deterministic operator stops churning the ConfigMap; the config hash stabilizes and the stuck resolver rolling update completes, leaving all three pods Ready on one revision.
