+# TiDB Operator 1.1.7 Release Notes
+
+Release date: November 13, 2020
+
+TiDB Operator version: 1.1.7
+
+## Compatibility Changes
+
+- The behavior of `prometheus.spec.config.commandOptions` has changed. Any duplicated flags must be removed, or Prometheus will fail to start. ([#3390](https://github.com/pingcap/tidb-operator/pull/3390), [@mightyguava](https://github.com/mightyguava))
+
+    Flags that CANNOT be set are:
+
+    - `--web.enable-admin-api`
+    - `--web.enable-lifecycle`
+    - `--config.file`
+    - `--storage.tsdb.path`
+    - `--storage.tsdb.retention`
+
+## New Features
+
+- Support `spec.toolImage` for the `Backup` and `Restore` CR with BR to define the image used to provide the BR binary executables. Defaults to `pingcap/br:${tikv_version}` ([#3471](https://github.com/pingcap/tidb-operator/pull/3471), [@namco1992](https://github.com/namco1992))
+- Add `spec.tidb.storageVolumes`, `spec.tikv.storageVolumes`, and `spec.pd.storageVolumes` to support mounting multiple PVs for TiDB, TiKV, and PD ([#3425](https://github.com/pingcap/tidb-operator/pull/3425) [#3444](https://github.com/pingcap/tidb-operator/pull/3444), [@mikechengwei](https://github.com/mikechengwei))
+- Add `spec.tidb.readinessProbe` config to support requesting `http://127.0.0.0:10080/status` for TiDB's readiness probe, TiDB version >= v4.0.9 required ([#3438](https://github.com/pingcap/tidb-operator/pull/3438), [@july2993](https://github.com/july2993))
+- Support PD leader transfer with advanced StatefulSet controller enabled ([#3395](https://github.com/pingcap/tidb-operator/pull/3395), [@tangwz](https://github.com/tangwz))
+- Support setting `OnDelete` update strategies for the StatefulSets via `spec.statefulSetUpdateStrategy` in the TidbCluster CR ([#3408](https://github.com/pingcap/tidb-operator/pull/3408), [@cvvz](https://github.com/cvvz))
+- Support HA scheduling when failover happens ([#3419](https://github.com/pingcap/tidb-operator/pull/3419), [@cvvz](https://github.com/cvvz))
+- Support smooth migration from TiDB clusters deployed using TiDB Ansible or TiUP or deployed in the same Kubernetes cluster to a new TiDB cluster ([#3226](https://github.com/pingcap/tidb-operator/pull/3226), [@cvvz](https://github.com/cvvz))
+- tidb-scheduler supports advanced StatefulSet ([#3388](https://github.com/pingcap/tidb-operator/pull/3388), [@cvvz](https://github.com/cvvz))
+
+## Improvements
+
+- Forbid to scale in TiKV when the number of UP stores is equal to or less than 3 ([#3367](https://github.com/pingcap/tidb-operator/pull/3367), [@cvvz](https://github.com/cvvz))
+- `phase` is added in `BackupStatus` and `RestoreStatus`, which will be in sync with the latest condition type and shown when doing `kubectl get` ([#3397](https://github.com/pingcap/tidb-operator/pull/3397), [@namco1992](https://github.com/namco1992))
+- Skip setting `tikv_gc_life_time` via SQL for backup and restore with BR when the TiKV version >= v4.0.8 ([#3443](https://github.com/pingcap/tidb-operator/pull/3443), [@namco1992](https://github.com/namco1992))
+
+## Bug Fixes
+
+- Fix the issue that PD cannot scale in to zero if there are other PD members outside of this `TidbCluster` ([#3456](https://github.com/pingcap/tidb-operator/pull/3456), [@dragonly](https://github.com/dragonly))

+
+发布日期：2020 年 11 月 13 日
+
+TiDB Operator 版本：1.1.7
+
+## 兼容性变化
+
+- 配置项 `prometheus.spec.config.commandOptions` 的行为发生了变化。该列表中不允许存在重复 flags，否则 Prometheus 无法启动。([#3390](https://github.com/pingcap/tidb-operator/pull/3390), [@mightyguava](https://github.com/mightyguava))
+
+    不能设置的 flags 有：
+
+    - `--web.enable-admin-api`
+    - `--web.enable-lifecycle`

+    - `--storage.tsdb.path`
+    - `--storage.tsdb.retention`
+
+## 新功能
+
+- 新增 `Backup` 和 `Restore` CR 的配置项 `spec.toolImage` 来指定 BR 工具使用的二进制镜像，默认使用 `pingcap/br:${tikv_version}` ([#3471](https://github.com/pingcap/tidb-operator/pull/3471), [@namco1992](https://github.com/namco1992))
+- 新增配置项 `spec.pd.storageVolumes`、`spec.tidb.storageVolumes` 和 `spec.tikv.storageVolumes`，支持为 PD、TiDB 和 TiKV 挂载多个 PV ([#3444](https://github.com/pingcap/tidb-operator/pull/3444) [#3425](https://github.com/pingcap/tidb-operator/pull/3425), [@mikechengwei](https://github.com/mikechengwei))
+- 新增配置项 `spec.tidb.readinessProbe`，支持使用 `http://127.0.0.0:10080/status` 作为 TiDB 的就绪探针，需要 TiDB 版本 >= v4.0.9 ([#3438](https://github.com/pingcap/tidb-operator/pull/3438), [@july2993](https://github.com/july2993))
+- PD leader transfer 支持 advanced StatefulSet 启用的情况 ([#3395](https://github.com/pingcap/tidb-operator/pull/3395), [@tangwz](https://github.com/tangwz))
+- 支持在 TidbCluster CR 中设置 `spec.statefulSetUpdateStrategy` 为 `OnDelete`，来控制 StatefulSets 的更新策略 ([#3408](https://github.com/pingcap/tidb-operator/pull/3408), [@cvvz](https://github.com/cvvz))
+- 支持故障转移发生时的高可用 (HA) 调度 ([#3419](https://github.com/pingcap/tidb-operator/pull/3419), [@cvvz](https://github.com/cvvz))
+- 支持将使用 TiDB Ansible 或 TiUP 部署的 TiDB 集群，以及在同一个 Kubernetes 上部署的 TiDB 集群，在线迁移到新的 TiDB 集群 ([#3226](https://github.com/pingcap/tidb-operator/pull/3226), [@cvvz](https://github.com/cvvz))
+- 在 tidb-scheduler 中支持 advanced StatefulSet ([#3388](https://github.com/pingcap/tidb-operator/pull/3388), [@cvvz](https://github.com/cvvz))
+
+## 优化提升
+
+- 当 UP 状态的 stores 数量小于等于 3 时，禁止缩容 TiKV 实例 ([#3367](https://github.com/pingcap/tidb-operator/pull/3367), [@cvvz](https://github.com/cvvz))

+
+## Bug 修复
+
+- 修复在当前 `TidbCluster` 之外存在 PD member 的情况下，当前 TiDB Cluster 无法把 PD scale 到 0 的 bug ([#3456](https://github.com/pingcap/tidb-operator/pull/3456), [@dragonly](https://github.com/dragonly))
