 ## [Unreleased]
 
+## [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

+- **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 …`）
+

-| 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.

-## Layout before and after
-
-### Before (typical v1.1.x)
-
-```
-/data
-├── pichost.db
-├── blog/
-│   └── 2026/08/TeKJ2fD6cB6j.webp
-├── twikoo/
-└── images/
-```
-
-Index keys might look like `blog/2026/08/TeKJ2fD6cB6j.webp`.
-
-### After (v1.2.0)
-
-```
-/data
-├── pichost.db
-├── mapping.json
-└── images/
-    ├── blog/
-    │   └── 2026/08/TeKJ2fD6cB6j.webp
-    └── 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.

+| **Create site backup** | Export `.phost.tar.gz` with `pichost.db` and all images (including objects on cloud backends); shows estimated size and package contents |
+| **Restore from backup** | Upload locally or pick an existing package under `data/backups/`, preview, then confirm; skip or overwrite conflicting images |

+- Uninitialized instances can use the **Restore backup** tab on `/setup` (always overwrite mode)

+docker exec pichost backup-restore /data/backups/pichost-xxx.phost.tar.gz
+docker exec pichost backup-restore /data/backups/pichost-xxx.phost.tar.gz --overwrite
+docker exec pichost storage-sync --from local --to s3-xxx --dry-run
+docker exec pichost storage-sync --from local --to s3-xxx --set-default

+
+Local development (project root):

+```bash
+npm run backup-export
+npm run backup-restore -- data/backups/pichost-xxx.phost.tar.gz
+npm run storage-sync -- --from local --to s3-xxx --dry-run

+
+### Manual backup
+
+You can still back up `data/images/`, `data/pichost.db`, and bucket objects directly; prefer the full-site export above.
