 # CHANGELOG
+## v0.3.0
+注意：v0.3.0 变更了部分实体 unique_id 的生成规则，如果勾选 xiaomi_home > 配置 > 更新实体转换规则，会导致部分实体已配置的自动化失效。如果想要避免重新配置大量自动化，可使用这个[补丁](https://github.com/XiaoMi/ha_xiaomi_home/pull/972)。
+
+CAUTION: v0.3.0 changes the unique_id of some entities. If you check the option `xiaomi_home > CONFIGURE > Update entity conversion rules`, it may cause the automation settings for these entities to fail. To avoid having to reconfigure a large number of automation settings, you can use this [patch](https://github.com/XiaoMi/ha_xiaomi_home/pull/972).
