 # Changelog
 
+## 2026-07-27 — [#1093](https://github.com/cobaltcore-dev/cortex/pull/1093)
+
+### cortex v0.3.4 (sha-4f44f3b7)
+
+Bug fixes:
+- Deep-copy capacity map to prevent informer cache corruption — the capacity filter assigned hypervisor Status.Capacity map references directly into a local working map, then mutated those maps during free-resource calculations. Since the maps are shared with the controller-runtime informer cache, each scheduling pass permanently decremented cached capacity values, progressively starving scheduling until all hosts appeared full ([#1065](https://github.com/cobaltcore-dev/cortex/pull/1065))
+- Reset gauge metrics in reservation monitor to prevent stale values — adds `Reset()` calls on `numberOfReservations` and `reservedResources` GaugeVecs before repopulating in `Collect`, preventing stale label combinations from persisting when reservations are deleted or change status ([#1092](https://github.com/cobaltcore-dev/cortex/pull/1092))
+- Stop committed resource controller reconcile storm — `setAccepted` unconditionally wrote a new AcceptedAt timestamp and a time-varying StatusSummary on every call, causing a non-empty status patch even when the CR was already accepted. Adds an early-return guard that skips the patch when Ready=True/Accepted is already set for the current generation ([#1089](https://github.com/cobaltcore-dev/cortex/pull/1089))
+
+Non-breaking changes:
+- Add History CRD documentation and multicluster guide link ([#1091](https://github.com/cobaltcore-dev/cortex/pull/1091))
+- Update `github.com/prometheus/client_golang` to v1.24.1 ([#1090](https://github.com/cobaltcore-dev/cortex/pull/1090))
+- Update `k8s.io/api`, `k8s.io/apimachinery`, `k8s.io/client-go` to v0.36.3 ([#1086](https://github.com/cobaltcore-dev/cortex/pull/1086))
+- Update `github.com/sapcc/go-bits` ([#1085](https://github.com/cobaltcore-dev/cortex/pull/1085))
+- Update `kube-prometheus-stack` to 87.19.2 ([#1090](https://github.com/cobaltcore-dev/cortex/pull/1090))

 In its state, decisions reflect the outcome of the pipeline execution, for example the generated weights for each scheduling step. This outcome is reflected back to the caller of the pipeline. In addition, decisions provide a human-readable explanation why the workload was placed at this specific location.
 
+### History
+
+```bash
+kubectl get histories
+```
+
+History is a cluster-scoped audit trail of scheduling decisions for a given resource (e.g., a Nova instance). Each time a pipeline produces a placement decision, the result — including which pipeline was used, the scheduling intent, the target host, and an explanation — is recorded unless the caller sets `SkipHistory=true` in the pipeline options. The most recent decision lives in `status.current`; older entries are compacted into `status.history`, capped at 10 entries.
