Full Release Notes

## 📦 升级指南

### 配置必填的 FE_DOMAIN

FastGPT 服务启动时会校验 `FE_DOMAIN`。请将它配置为客户端访问 FastGPT 时使用的地址,该地址由协议、主机和可选端口组成。公网部署应填写客户端实际使用的公网访问地址;本地开发可使用 `http://localhost:3000`。

```bash
FE_DOMAIN=https://fastgpt.example.com
```

### MongoDB 索引同步调整

V4.15.4 起,`SYNC_INDEX` 弃用,新增 `MONGO_DEPRECATE_INDEX` 环境变量,用于控制是否清理 Schema 显式标记的废弃索引,默认值为 `true`。设置为 `false` 时只跳过废弃索引清理,不影响当前 Schema 缺失索引的创建。

FastGPT 启动时会自动执行安全的主动同步:

- 创建当前 FastGPT Schema 中缺失的索引。
- 仅删除对应 Schema 明确标记为废弃、且 name、key 和关键 options 完全匹配的 FastGPT 系统内置历史索引。
- 保留客户自建索引及其他未声明的索引。

该同步不会调用 Mongoose 的全量 `syncIndexes()`,因此不会按“未在 Schema 中声明”这一条件批量删除索引。

> **默认开启与删除边界:`MONGO_DEPRECATE_INDEX` 默认为 `true`,仅删除 FastGPT Schema 显式声明为废弃、且索引定义精确匹配的系统内置索引,不会删除客户自建索引。建议为自建索引显式设置自定义名称,不要使用 MongoDB 按 key 生成的默认名称,避免与 FastGPT 系统内置索引重名。**

> **旧索引清理说明:V4.15.4 不会把任何已有历史索引标记为废弃,因此升级到该版本时不会自动删除旧索引。后续版本会在确认安全后,通过 Schema 中的显式废弃标记逐步清理对应索引。**

如需在升级 V4.15.4 前完整删除历史过期索引,请按以下顺序操作:

1. 先升级并启动一次 V4.15.3。
2. 设置 `SYNC_INDEX=true`,重启服务并等待索引同步完成。
3. 确认索引同步成功后,再升级至 V4.15.4。

V4.15.3 的索引同步会删除所有未在当时 Schema 中声明的索引,其中可能包含客户自建索引。执行上述步骤前,请先备份数据库并检查现有索引;如需保留自建索引,请记录其定义并在同步后重新创建,或不要使用 V4.15.3 进行全量清理。

`MONGO_DEPRECATE_INDEX=false` 会跳过未来版本可能声明的废弃索引清理,但不会跳过缺失索引的创建。
