+# Announcing KubeBlocks v1.0.2
+
+We are delighted to announce the release of KubeBlocks v1.0.2. This release includes several new features, bug fixes, and various improvements. Here are the detailed update contents.
+
+## KubeBlocks
+
+### Features
+
+- **Make StorageClass reclaimPolicy configurable** - Allows configuring StorageClass reclaimPolicy via values.yaml when deploying KubeBlocks. ([#10040](https://github.com/apecloud/kubeblocks/pull/10040))
+- **Support specifying an update policy for the upgrade operation** - Allows specifying update policies for upgrade operations. ([#9736](https://github.com/apecloud/kubeblocks/pull/9736))
+- **Support referencing the service version in vars** - Enables referencing service versions in variables. ([#9735](https://github.com/apecloud/kubeblocks/pull/9735))
+
+### Bug Fixes
+
+- **Fix `persistentVolumeClaimRetentionPolicy` not working** - Ensures PVCs are kept on `Retain` policy when the cluster is deleted or scaled down. ([#10043](https://github.com/apecloud/kubeblocks/pull/10043))

+
+## Breaking Changes
+
+### Variable Rendering Fix ([#9935](https://github.com/apecloud/kubeblocks/pull/9935))
+
+Variable rendering now passes `map[string]any` instead of `map[string]string`. Addons that relied on the old behavior may need template updates.
+
+**Before (KB 1.0.1 and earlier)** — workaround for string-only vars:
+
+```text
+{{if ne (index . "ENDPOINT_PORT") ""}}{{.ENDPOINT_PORT}}{{else}}5022{{end}}
+```
+
+**After (KB 1.0.2)** — simplified expression:
+
+```text
+{{if index . "ENDPOINT_PORT"}}{{.ENDPOINT_PORT}}{{else}}5022{{end}}
+```
+
+**Affected addons**: OceanBase, MongoDB, Redis, Redis Cluster. See [Issue #9934](https://github.com/apecloud/kubeblocks/issues/9934) for context.
+
+**Symptoms**
+
+After upgrading to KubeBlocks v1.0.2, existing clusters that use the OceanBase, MongoDB, Redis, or Redis Cluster addons may show:
+
+1. When you run `kubectl describe component`, events similar to:
+
+    ```bash
+    template: vars:1:50: executing "vars" at <.REDIS_HOST_NETWORK_PORT>: map has no entry for key "REDIS_HOST_NETWORK_PORT"
+    ```
+
+2. In the KubeBlocks operator logs, errors similar to:
+
+    ```bash
+    INFO	ComponentParameterReconciler	failed to create task context: template: vars:1:50: executing "vars" at <.REDIS_HOST_NETWORK_PORT>: map has no entry for key "REDIS_HOST_NETWORK_PORT"	{"controller": "componentparameter", "controllerGroup": "parameters.kubeblocks.io", "controllerKind"
+    ```
+
+**Resolution**
+
+- **Option 1 — In-place fix**: Follow the approach in [PR #2328](https://github.com/apecloud/kubeblocks-addons/pull/2328) and update the variable rendering logic in the affected ComponentDefinition locally. If `ComponentDefinition` goes `UNAVAILABLE`, pls annotate the `ComponentDefinition` CR to allow the changes.
+    ```bash
+    kubectl annotate cmpd <COMPONENT_DEFINITION_NAME> apps.kubeblocks.io/skip-immutable-check=true
+    ```
+- **Option 2 — Upgrade addon and migrate clusters**: Upgrade the affected addon, then migrate existing clusters to the new addon version one by one. See [Migrate Existing Clusters to a New Addon Version](https://kubeblocks.io/docs/preview/user_docs/upgrade/migrate-clusters-to-new-addon).
