Show resolved Hide resolved

发版日期：2023 年 1 月 xx 日

TiDB 版本：6.5.1

试用链接：[快速体验](https://docs.pingcap.com/zh/tidb/v6.5/quick-start-with-tidb) | [生产部署](https://docs.pingcap.com/zh/tidb/v6.5/production-deployment-using-tiup) | [下载离线包](https://cn.pingcap.com/product-community/?version=v6.5.1#version-list)

## 兼容性变更

- 自 2023 年 2 月 20 日起，新发布的 TiDB 和 TiDB Dashboard 版本（包含 6.5.1），默认关闭[遥测功能](/telemetry.md)，即默认不再收集使用情况信息分享给 PingCAP。如果升级至这些版本前使用默认的遥测配置，则升级后遥测功能处于关闭状态。具体的版本可参考 [TiDB 版本发布时间线](/releases/release-timeline.md)。

- 系统变量 [`tidb_enable_telemetry`](/system-variables.md#tidb_enable_telemetry-从-v402-版本开始引入) 默认值由 `ON` 修改为 `OFF`。
- TiDB 配置项 [`enable-telemetry`](/tidb-configuration-file.md#enable-telemetry-从-v402-版本开始引入) 默认值由 `true` 改为 `false`。
- PD 配置项 [`enable-telemetry`](/pd-configuration-file.md#enable-telemetry) 默认值由 `true` 改为 `false`。

- 从 v1.11.3 起，新部署的 TiUP 默认关闭遥测功能，即默认不再收集使用情况信息。如果从 v1.11.3 之前的 TiUP 版本升级至 v1.11.3 或更高 TiUP 版本，遥测保持升级前的开启或关闭状态。
