## ⚠️ Breaking Changes

### AOF persistence layout changed

The legacy single `record.aof` file is no longer loaded. AOF remains the incremental write log: persisted data now uses numbered snapshots alongside rotated AOF log files in the database directory.

**Migration:**

1. Open the database with `v0.5.2` and export its records through the existing application or store API.
2. Upgrade to `v0.6.0`.
3. Import the exported records into a new database directory.
4. Retain the old `record.aof` until the imported data is verified.

<summary>翻譯</summary>

不再讀取舊版單一 `record.aof` 檔案。AOF 仍保留作為增量寫入日誌；資料庫目錄現在使用編號快照搭配輪替的 AOF 日誌檔。

**遷移方式：**

1. 使用 `v0.5.2` 透過既有應用程式或 Store API 匯出資料。
2. 升級至 `v0.6.0`。
3. 將匯出資料匯入新的資料庫目錄。
4. 驗證匯入資料前，保留舊的 `record.aof`。
