+## [Unreleased]
+
+## [1.5.0] - 2026-10-17
+
+### 新增
+

+
+## [1.2.8] - 2026-09-04

+
+### 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

+
+### 改进
+
+- README 补充技术栈说明
+
+### 移除
+
+- `/stats` 路由（不再兼容跳转）
+
+## [1.2.4] - 2026-08-31
+
+### 修复
+
+- 访问控制（Referer 防盗链）留空时仍会拦截外链图片：浏览器直开无 Referer 可访问，博客/论坛嵌入带 Referer 会 403 图裂；现仅在配置了白名单时才校验
+
+## [1.2.3] - 2026-08-30
+
+### 修复
+
+- 开启「简短图片链接」且按年/月分组时，纯文件名直链（如 `/xxx.webp`）误解析为 `images/xxx.webp` 导致 404；现先经 SQLite 索引反查完整 key
+
+## [1.2.2] - 2026-08-30
+
+### 修复
+
+- 双域名：设置页保存时误清空管理域（`site_base_url`）；仅改图片域时保护已有网站域配置
+- 双域名：设置 API 配置值与 request origin fallback 混淆，导致「当前生效」显示错误
+- 双域名：未配置的第三 Host（`pages.dev`、裸 IP 等）可绕过 Host 隔离访问后台
+
+### 改进
+
+- 设置 API 拆分 `siteBaseUrl` / `imageBaseUrl`（配置值）、`effective*`（直链）、`runtime`（当前访问检测）
+- `PATCH /api/settings` 增加 `domainSeparation` 字段与保存校验
+- 设置页：检测地址展示、关闭双域名确认、反代 Host 不一致警告；首次设置不再自动填入 origin
+- Host 中间件：双域名开启时对未知 Host 返回 404（开发 `localhost` 例外）
+- 文档站：新增 [更新日志](https://o96u.github.io/PicHost/guide/changelog)；重写 Cloudflare 部署说明；同步 FAQ / 双域名文档
+
+## [1.2.1] - 2026-08-29
+
+### 新增
+
+- 登录滑动拼图验证（缺口对齐）；验证与登录分两步，登录接口校验 `captchaId` / `captchaPosition`
+- VitePress 文档站（`docs-site/`）：中英文指南，部署至 GitHub Pages <https://o96u.github.io/PicHost/>
+- `npm run docs:dev` / `docs:build` / `docs:preview`；CI 增加 `docs:build`；`.github/workflows/docs.yml` 发布文档
+
+### 修复
+
+- 修复统计页删除图片后图库不刷新的问题
+- 修复分页跳转输入框在 `type="number"` 下无法跳转的问题
+- 修复非首页路由下复制链接格式偏好不持久化的问题（`useUploadPreferences` 首次使用时自动加载）
+- 滑动验证 UI：滑块垂直居中、缺口尺寸与滑块一致
+
+### 改进
+
+- README 精简为产品宣传页，详细说明指向文档站
+- 双域名文档补充：未知 Host 风险、Cloudflare 橙云部署、勿用 Pages/Workers 整站反代
+- 文档截图更新（登录页等）；旧 `docs/*.md` 长文迁入 `docs-site/`
+
+## [1.2.0] - 2026-08-28
+
+### 变更
+
+- 图片统一存放在 `data/images/`；遗留 `blog/`、`twikoo/` 等并列目录需迁移后升级
+
+### 新增
+
+- CLI 迁移工具：`docker exec pichost migrate` / `migrate --apply`（`server/cli/migrate-to-single-images.mjs`）
+- 扫描 `data/` 下除 `images` 外所有顶层目录中的图片，输出 `data/mapping.json`
+- 启动时自动同步图片索引（扫描磁盘、归一化遗留 key、清理孤儿记录），并打印同步日志
+
+### 改进
+
+- 启动时归一化遗留 SQLite key、清理无文件的孤儿索引；支持删除仅索引无文件的记录
+
+## [1.1.5] - 2026-08-28
+
+### 修复
+
+- 修复 API 上传后图库预览偶发失败、需等待刷新才显示的问题
+- 图库卡片加载失败后自动重试，刷新列表时重置预览状态
+
+### 改进
+
+- 出图前校验存储文件实际存在，避免索引与磁盘短暂不一致
+- 图片 404/403 与域名隔离 404 禁止 CDN 缓存，降低反代误判影响
+

 ## Features
 
-- **Drag, click, or Ctrl+V paste** to upload; admins can use custom `folder` paths
+- **Drag, click, or Ctrl+V paste** — server-side WebP, Referer hotlink protection
-- **Server-side WebP** (sharp), Referer hotlink protection, configurable public base URL
+- **Multi-user** — login with slider, Turnstile, or Cap verification; optional registration; users see only their images
-- **Multi-user** — username/password login; optional registration; users see only their images
+- **Multi-backend storage** — local disk + S3-compatible (R2 / COS / OSS / AWS) + Telegram channel/group; hybrid `proxy` / `public` URLs
-- **Upload preferences** (home card flip): client-side compression, auto-copy links, per-user auto-delete
+- **Gallery** — browse, search, filter by storage/source/tags, grid/list views, batch delete and batch tagging; stats overview and source breakdown; image detail modal with link formats
-- **Multi-backend storage**: local disk + S3-compatible (Cloudflare R2 / Tencent COS / Alibaba OSS / AWS S3); admins manage backends at **Storage** (`/storage`)
+- **Tags** — per-user colored tags; tag on upload (single or batch); manage in Settings (create, recolor, merge, delete); API supports `tagIds` and batch tagging
-- **Hybrid URLs**: `proxy` (same-origin via PicHost) or `public` (302 to CDN / bucket URL)
+- **Backup & migration** — full-site export/restore (`.phost.tar.gz`), cross-backend sync; restore from backup on uninitialized `/setup`
-- **Gallery** — browse, search, batch delete; admin sees uploader badges
+- **API & Twikoo** — global / per-user tokens; `POST /api/index.php` compatible
-- **Stats** — upload/delete metrics, folder breakdown; admin sees registered user count
+- **Zero-config Docker** — first-run web wizard, no secrets upfront

-## Storage layout
-
-```
-/data
-├── pichost.db          # SQLite: users, sessions, settings, storage_backends, images index
-├── images/             # Default upload folder (when using local backend)
-├── blog/               # Example custom folder
-└── twikoo/             # Twikoo comment images
-```
-
-Pattern: `folder/YYYY/MM/randomId.webp` + `.meta.json`. With cloud backends, blobs live in the bucket; SQLite `images` tracks `backend_id` and `key`. Back up all of `/data` plus bucket data.
-
-## API overview
-
-| Method | Path                 | Description            |
-| ------ | -------------------- | ---------------------- |
-| POST   | `/api/images/upload` | Upload image           |
-| GET    | `/api/images`        | Paginated list         |
-| DELETE | `/api/images`        | Delete one (`key`)     |
-| POST   | `/api/index.php`     | Twikoo / EasyImage 2.0 |
-
-Upload example:
-
-```bash
-curl -X POST "https://pic.example.com/api/images/upload" \
-  -H "Auth-Token: YOUR_TOKEN" \
-  -F "folder=blog" \
-  -F "image=@./demo.png"
-```
-
-Full docs and copyable cURL snippets are on the **API** page after deployment.
-
-## Twikoo
-
-| Setting           | Value                               |
-| ----------------- | ----------------------------------- |
-| `IMAGE_CDN`       | `easyimage`                         |
-| `IMAGE_CDN_URL`   | `https://your-domain/api/index.php` |
-| `IMAGE_CDN_TOKEN` | Same as `API_UPLOAD_TOKEN`          |
-
-## Reverse proxy
-
-- Proxy to port **6892**; HTTPS recommended
-- Nginx: `client_max_body_size` ≥ 12m
-- Set `IMAGE_BASE_URL` (single domain) or `SITE_BASE_URL` + `IMAGE_BASE_URL` (dual-domain separation)
-
-### Recommended architecture (dual domains)
-
-**One Docker instance + two domains**, both fully proxied to `6892` (isolation via PicHost middleware):
-
-```nginx
-# admin.example.com — admin + API + images
-server {
-  server_name admin.example.com;
-  location / {
-    proxy_pass http://127.0.0.1:6892;
-    proxy_set_header Host $host;
-    proxy_set_header X-Forwarded-Proto $scheme;
-    client_max_body_size 12m;
-  }
-}
-
-# pic.example.com — same full proxy; PicHost middleware blocks non-image paths
-server {
-  server_name pic.example.com;
-  location / {
-    proxy_pass http://127.0.0.1:6892;
-    proxy_set_header Host $host;
-    proxy_set_header X-Forwarded-Proto $scheme;
-  }
-}
-```
-
-FN NAS [Lucky](https://github.com/gdy666/lucky) reverse proxy (public hostname → backend `http://<LAN-IP>:6892`):
-
-| Site domain (admin) | Image domain |
-| :-----------------: | :----------: |
-| ![Lucky site](docs/screenshots/lucky-site.png) | ![Lucky image](docs/screenshots/lucky-image.png) |
-
-See **[docs/domain-separation.en.md](docs/domain-separation.en.md)** for Caddy/NPM notes, env vars, and setup fields.
-
-## Development
-
-```bash
-npm run dev          # Dev server
-npm run build        # Production build
-npm run start        # Run .output
-npm run lint         # ESLint

-## 反向代理
-
-- 反代到容器 **6892** 端口，建议 HTTPS
-- Nginx：`client_max_body_size` ≥ 12m
-- 公网访问请配置 `IMAGE_BASE_URL`（单域名）或 `SITE_BASE_URL` + `IMAGE_BASE_URL`（双域名分离）
-
-### 推荐部署架构（双域名分离）
-
-**单 Docker 实例 + 两个域名** 均可全量反代到 `6892`（隔离由 PicHost 中间件负责）：
-
-```nginx
-# admin.example.com — 后台 + API + 出图
-server {
-  server_name admin.example.com;
-  location / {
-    proxy_pass http://127.0.0.1:6892;
-    proxy_set_header Host $host;
-    proxy_set_header X-Forwarded-Proto $scheme;
-    client_max_body_size 12m;
-  }
-}
-
-# pic.example.com — 同样全量反代；PicHost 中间件会拦截非图片路径
-server {
-  server_name pic.example.com;
-  location / {
-    proxy_pass http://127.0.0.1:6892;
-    proxy_set_header Host $host;
-    proxy_set_header X-Forwarded-Proto $scheme;
-  }
-}
-```
-
-飞牛 NAS [Lucky](https://github.com/gdy666/lucky) 反向代理示例（前端域名 → 后端 `http://<内网IP>:6892`）：
