 ## [Unreleased]
 
+## [1.4.3] - 2026-10-09
+
+### 新增
+
+- **Telegram 存储后端**：用 Bot 把图片存入频道或群组（含私有）；直链仍由 PicHost 代理，不暴露 Bot Token
+- 可选 HTTP/HTTPS API 代理，供服务器访问 Telegram
+- 群组升级为超级群组时自动改用新的 Chat ID
+
+### 说明
+
+- 单文件约 20MB，同一聊天约 20 条/分钟
+- 图库删除会尝试删除对应 Telegram 消息；备份包不含 Bot Token
+
+## [1.4.2] - 2026-09-23
+
+### 修复
+
+- 图库批量打标：管理员/跨归属场景下标签解析与失败提示
+- 上传鉴权：`Auth-Token` 与表单 `token` 优先于会话；兼容全局 `API_UPLOAD_TOKEN`（上传归属首位管理员）
+
+### 改进
+
+- **API 页**：每账号单一 API Token，界面与文档统一
+- **上传 API**：仅支持 `tagNames`（按名创建或复用标签）；Twikoo 兼容路由同步
+- **标签管理**：按图片数/最近使用排序；桌面列布局；窄屏卡片列表
+- **API 文档**：参数表列宽，避免 form-data 列异常换行
+
+## [1.4.1] - 2026-09-16
+
+### 新增
+
+- **上传策略（设置 → 基础）**：单文件大小、允许格式、上传/登录限流、保留原图（关闭服务端 WebP 转换）；支持 `.env` 覆盖
+- **上传 API**：可选 `tagNames`（名称不存在则创建，存在则复用）；与 `tagIds` 可并用
+
+### 改进
+
+- 登录接口接入可配置的登录限流
+- 设置页将全站上传策略并入「上传偏好 / 图片处理」；访问控制保留登录限流
+- API 文档补充 `tagIds` / `tagNames` 参数说明
+
+## [1.4.0] - 2026-09-09
+
+### 新增
+
+- **标签系统**：每用户独立标签与彩色标记；设置页管理（新建、改色、合并、删除）
+- **图片打标**：上传后单张/批量打标；图库按标签筛选（OR / AND）、批量打标与解标
+- **操作日志扩展**：记录登录、删除、设置变更、标签操作等；支持日期、用户、操作类型、来源与 IP 筛选
+- **API**：标签 CRUD、图片打标、`batch-tags`；上传支持 `tagIds`；列表/搜索/统计支持标签筛选
+
+### 改进
+
+- 操作日志页 UI 改版（操作/来源徽章、移除备注列）
+- 设置侧栏增加「标签管理」
+
+### 文档
+
+- README 与文档站截图更新（上传、图库、标签、操作日志等）
+
+## [1.3.0] - 2026-09-07
+
+### 新增
+
+- **站点备份**：存储页导出 `.phost.tar.gz`（含 `pichost.db` 与全部图片），支持下载与任务进度
+- **站点恢复**：存储页或 setup 未初始化时从备份包恢复，支持预检与跳过/覆盖冲突
+- **跨后端同步**：在已配置存储后端之间拷贝图片并更新索引；后端卡片快捷「迁入 / 迁出」
+- **任务中心**：`backup_jobs` 记录最近导出/恢复/同步任务，失败可重试；列表分页
+- 运维 CLI：`backup-export`、`backup-restore`、`storage-sync`（`docker exec pichost …`）
+
+### 移除
+
+- 遗留目录迁移 CLI `migrate` / `migrate-to-single-images.mjs`（由启动索引同步与整站备份恢复替代）
+
+### 文档
+
+- [存储](./docs-site/guide/storage.md) 补充备份与迁移说明；更新截图；移除 v1.2 迁移专页
+
+## [1.2.8] - 2026-09-04
+
+### 改进
+
+- 双域名：保存或初始化时弹出风险确认（说明可能锁死及 `clear-domains` 恢复方式），不再强制校验当前 Host
+
+### 新增
+
+- 运维 CLI `clear-domains`：清除数据库中的网站域 / 图片域配置（`docker exec pichost clear-domains`）
+
+### 文档
+
+- FAQ、双域名、反向代理文档补充锁死原因与恢复步骤
+
+## [1.2.7] - 2026-09-03
+
+### 新增

+## Admin 404 / locked out after dual-domain setup?
+
+**Cause:** With dual-domain enabled, PicHost returns **404 for every request** whose Host is not the configured site or image hostname. Common triggers:
+

-# v1.2.0 local disk migration guide
-
-From v1.2.0, **all local image files** live under `data/images/`; SQLite `keys` also start with `images/`. Legacy top-level folders next to `images` (e.g. `data/blog/`, `data/twikoo/`) are no longer used.
-
-Migration is **two steps**: run the **CLI** to move files on disk, then let **startup sync** align the SQLite index.
-
----
-
-## Migrating from other image hosts (EasyImage, Lsky, Chevereto, …)
-
-There is **no** dedicated “pull from URLs” or “import via vendor API” tool. Moving from **legacy PicHost** or **another self-hosted** install uses the same **local file** workflow:
-
-1. Locate the **image files** on the old server (copy the tree, not just the database).
-2. Place them under PicHost `data/` as a **top-level folder** next to `images` (any name — it becomes `images/{name}/...`).
-3. Run `migrate` / `migrate --apply`, then restart PicHost.
-
-| Source | Typical path on old server | After copy into PicHost |
-| ------ | -------------------------- | ----------------------- |
-| PicHost v1.1.x | `data/blog/`, `data/twikoo/` | Already under `data/` → run `migrate` |
-| EasyImage(s) | `i/` or `upload/` | e.g. `data/easyimage/` → `migrate` |
-| Lsky | `public/uploads/` etc. | e.g. `data/lsky/` → `migrate` |
-| Chevereto etc. | `images/` or `content/` | e.g. `data/chevereto/` → `migrate` |
-| Custom | your folder name | `data/your-folder/` → `migrate` |
-
-The CLI scans **every top-level directory under `data/` except `images`**, not only `blog` / `twikoo`.
-
-**Limits:** files only — accounts, tokens, and old public URLs are not imported. `mapping.json` maps old **storage keys**, not full old-site URLs. For S3/R2-only legacy hosts, sync blobs to `data/…` or attach the bucket in PicHost **Storage** settings.
-
----

-    └── twikoo/
-```
-
-Index key: `images/blog/2026/08/TeKJ2fD6cB6j.webp`.
-
----
-
-## Step 1: CLI file migration
-
-Run **before or after** upgrading the image; backup `data/` first.
-
-```bash
-docker exec pichost migrate          # preview + mapping.json
-docker exec pichost migrate --apply  # move files
-```
-
-Local: `npm run migrate` / `npm run migrate -- --apply`.
-
-| Item | Behavior |
-| ---- | -------- |
-| Scan | Every top-level directory under `data/` **except `images`** |
-| Target | `data/images/{original-top-dir}/{relative-path}` |
-| Extensions | jpg, jpeg, png, webp, gif, svg, ico |
-| Sidecar | `.meta.json` next to an image is moved if present |
-| Other files | Not moved; parent directory kept if anything remains |
-| Mapping | `data/mapping.json` — old key → new key |
-
-Script: `server/cli/migrate-to-single-images.mjs`.
-
----
-
-## Step 2: Startup index sync (automatic)
-
-Runs on every start (`npm run dev`, Docker). No manual command.
-
-```text
-[INFO] 开始同步图片索引：扫描本地磁盘 ...
-[INFO] 磁盘扫描完成：...
-[INFO] 开始归一化遗留图片路径 ...
-[INFO] 开始校验索引与磁盘一致性，清理无文件的孤儿记录
-[INFO] 图片索引同步结束
-```
-
-| Step | Purpose |
-| ---- | ------- |
-| Scan `data/images/` | Insert missing index rows for files on disk |
-| Normalize legacy keys | `blog/...` → `images/blog/...` when files are in place |
-| Purge orphans | Remove index rows with no file on disk |
-| Repair Content-Type | Fix `application/octet-stream` entries |
-
-The CLI only **moves files**. Index alignment runs at startup — **restart** after `migrate --apply`.
-
----
-
-## Recommended upgrade flow
-
-1. Backup `data/`.
-2. `docker exec pichost migrate` — review output and `mapping.json`.
-3. `docker exec pichost migrate --apply`.
-4. Deploy v1.2.0 and restart.
-5. Check logs for successful index sync.
-6. Use `mapping.json` to update external URLs if needed.
-
-Skip step 1 if you only use object storage or everything is already under `data/images/`.
-
----
-
-## URLs
-
-| Old key | `blog/TeKJ2fD6cB6j.webp` |
-| New key | `images/blog/TeKJ2fD6cB6j.webp` |
-
-With “hide folder” mode, short URLs like `/TeKJ2fD6cB6j.webp` may still resolve by filename. Use `mapping.json` for bulk replacements.

-
-迁移分 **两步**：先用手动 CLI **搬文件**，再由服务 **启动时自动同步索引**。
-
----
-
-## 从其它图床迁入（EasyImage / 兰空 / Chevereto 等）
-
-**没有**单独的「一键从外链拉取」或「对接某某图床 API」工具。从 **PicHost 旧版** 或其它自托管图床迁入，走的是同一套 **本地文件迁移**：
-
-1. 在旧图床服务器上找到图片**物理目录**（整目录拷贝，不要只拷数据库）。
-2. 把该目录放到 PicHost 的 `data/` 下，作为与 `images` **并列的顶层文件夹**（文件夹名任意，会保留为 `images/{文件夹名}/...`）。
-3. 执行 `migrate` / `migrate --apply`，再重启 PicHost。
-
-### 常见来源示例
-
-| 来源 | 典型图片目录（在旧服务器上） | 放入 PicHost 后示例 |
-| ---- | ---------------------------- | ------------------- |
-| PicHost v1.1.x | `data/blog/`、`data/twikoo/` | 已在 `data/` 下，直接 `migrate` |
-| EasyImage / EasyImages | `i/` 或安装目录下的 `upload/` | 拷到 `data/easyimage/` 再 `migrate` |
-| 兰空图床 (Lsky) | `public/uploads/` 等 | 拷到 `data/lsky/` 再 `migrate` |
-| Chevereto 等 | `images/` 或 `content/` | 拷到 `data/chevereto/` 再 `migrate` |
-| 任意自定义目录 | 你的顶层文件夹名 | 拷到 `data/你的目录名/` 再 `migrate` |
-
-脚本会扫描 `data/` 下**除 `images` 外所有顶层目录**里的图片，不限于 `blog` / `twikoo`。子目录结构会原样保留在 `images/{顶层名}/` 下。
-
-### 操作示例（Docker）
-
-```bash
-# 在宿主机：把从旧图床打包的目录放进挂载卷（名称自定）
-# 例如：./data/easyimage/2026/01/photo.jpg
-
-docker exec pichost migrate          # 预览
-docker exec pichost migrate --apply
-# 重启容器 → 启动日志会补全 SQLite 索引
-```
-
-### 说明与限制
-
-- **只迁移文件**：旧图床的账号、Token、外链 URL **不会**自动导入；`mapping.json` 里的 key 是「旧磁盘相对 key → 新 key」，**不是**旧站完整 URL，替换外链需自行对照。
-- **对象存储**：若旧图床图片在 S3/R2 桶里，请用桶工具同步到本地 `data/某目录/`，或直接在 PicHost **存储**页配置同一桶（不经过本 CLI）。
-- **已直接在 `data/images/` 下**：无需 `migrate`，重启后启动同步会自动建索引。

-```
-
-对应 `key`：`images/blog/2026/08/TeKJ2fD6cB6j.webp`。
-
----
-
-## 第一步：CLI 迁移磁盘文件
-
-在 **升级镜像之前或之后**均可执行；建议在升级前完成，并先备份整个 `data/` 目录。
-
-### Docker
-
-```bash
-# 预览：列出待迁移文件，写入 data/mapping.json（旧 key → 新 key）
-docker exec pichost migrate
-
-# 确认无误后执行文件移动
-docker exec pichost migrate --apply
-```
-
-### 本地开发
-
-```bash
-npm run migrate              # 预览
-npm run migrate -- --apply   # 执行
-```
-
-### 脚本行为
-
-| 项目 | 说明 |
-| ---- | ---- |
-| 扫描范围 | `data/` 下**除 `images` 外所有顶层目录**（不限于 blog/twikoo） |
-| 迁移目标 | `data/images/{原顶层目录名}/{相对路径}` |
-| 图片类型 | `.jpg` `.jpeg` `.png` `.webp` `.gif` `.svg` `.ico` |
-| 伴随文件 | 若存在同名的 `.meta.json` 会一并移动 |
-| 非图片文件 | 不移动；若目录内仍有其它文件，**保留原目录**不删除 |
-| 映射表 | `data/mapping.json`，例如 `"blog/foo.webp": "images/blog/foo.webp"` |
-
-脚本路径：`server/cli/migrate-to-single-images.mjs`。
-
----
-
-## 第二步：启动时自动同步索引
-
-每次 PicHost 启动（`npm run dev`、Docker 容器启动）会自动执行，**无需手动命令**。日志示例：
-
-```text
-[INFO] 开始同步图片索引：扫描本地磁盘 {"path":".../data/images/"}
-[INFO] 磁盘扫描完成：已补全缺失索引 {"inserted":3}
-[INFO] 开始归一化遗留图片路径（如 blog/ → images/blog/）
-[INFO] 遗留路径归一化完成：无需调整
-[INFO] 开始校验索引与磁盘一致性，清理无文件的孤儿记录
-[INFO] 孤儿索引清理完成：未发现孤儿记录
-[INFO] 开始修复存量 Content-Type 元数据
-[INFO] Content-Type 修复完成：无需修复
-[INFO] 图片索引同步结束
-```
-
-| 步骤 | 作用 |
-| ---- | ---- |
-| 扫描 `data/images/` | 磁盘上有、索引里没有 → **补全** `images` 表 |
-| 归一化遗留 key | 将 `blog/...` 等旧 key 更新为 `images/blog/...`（文件已在正确路径时） |
-| 清理孤儿索引 | 索引里有记录、磁盘无文件 → **删除**幽灵记录（避免图库出现删不掉的项） |
-| 修复 Content-Type | 修正错误的 `application/octet-stream` |
-
-CLI 只负责**搬文件**；索引对齐、遗留 key、孤儿记录由启动同步处理。执行 `migrate --apply` 后**重启一次**服务即可。
-
----
-
-## 推荐升级流程
-
-1. **备份** `data/`（含 `pichost.db` 与各目录）。
-2. `docker exec pichost migrate` 预览，检查输出与 `mapping.json`。
-3. `docker exec pichost migrate --apply` 执行迁移。
-4. 拉取 / 部署 **v1.2.0** 镜像并重启容器。
-5. 查看启动日志，确认「图片索引同步结束」无报错。
-6. 用 `mapping.json` 批量替换博客、Twikoo 等外链中的旧路径（若需要）。
-
-仅使用对象存储、或图片早已全部在 `data/images/` 下时，**跳过第一步**；第二步仍会在启动时运行，通常几秒内完成且无变更日志。

-## 外链与直链
-
-| 场景 | 说明 |
-| ---- | ---- |
-| 旧 key | `blog/TeKJ2fD6cB6j.webp` |
