+### 新功能
+
+#### 任务调度器（Task Scheduler）
+一个灵活的任务调度系统，用于管理 Ray Worker 节点上的周期性维护任务。
+
+**内置任务：**
+- **ImageCleanupTask**：使用 [docuum](https://github.com/stepchowfun/docuum) 进行 Docker 镜像清理，支持可配置的磁盘阈值
+
+**配置示例：**
+```yaml
+scheduler:
+  enabled: true
+  worker_cache_ttl: 3600
+  tasks:
+    - task_class: "rock.admin.scheduler.tasks.image_cleanup_task.ImageCleanupTask"
+      enabled: true
+      interval_seconds: 3600
+      params:
+        threshold: "1T"
+```
+
+**可扩展性：**
+通过继承 `BaseTask` 并实现 `run_action(runtime: RemoteSandboxRuntime)` 方法来创建自定义任务。
+
+#### Entrypoints
+
+- **新增**: 批量查询沙箱状态 API (`POST /sandboxes/batch`)
+  - 在单个请求中高效检索多个沙箱的状态信息
+  - 接受包含 `sandbox_ids` 列表的 `BatchSandboxStatusRequest` 请求
+  - 返回包含所有请求沙箱状态详情的 `BatchSandboxStatusResponse` 响应
+  - 支持可配置的最大数量限制（默认值来自 `batch_get_status_max_count` 配置）
+
+- **新增**: 沙箱列表和过滤 API (`GET /sandboxes`)
+  - 使用灵活的查询参数查询和过滤沙箱
+  - 通过 `page` 和 `page_size` 参数支持分页
+  - 返回包含条目列表、总数和 `has_more` 标识的 `SandboxListResponse` 响应
+  - 支持按沙箱属性过滤（例如：部署类型、状态、自定义元数据等）
+  - 最大页面大小可通过 `batch_get_status_max_count` 配置
+
+#### Sandbox
+
+- 修改 Sandbox 日志格式：时间戳使用 ISO 8601 格式，默认时区为 Asia/Shanghai（亚洲/上海）
+- 丰富 SandboxInfo：添加 create_time、start_time、stop_time
+- 添加计费日志：当 sandbox 关闭时记录计费日志
+
+---
+
+### 增强
+
+#### 性能优化
+- 实现 get_status 接口逻辑与 Ray 的解耦：将 API 响应耗时从 1s 以上显著降低至 100ms 级别；支持新旧逻辑的动态在线切换。
+- 将ray相关操作从sandbox manager中下沉至ray service。

+### New Features
+
+#### Task Scheduler
+A flexible task scheduling system for managing periodic maintenance tasks across Ray workers.
+
+**Built-in Tasks:**
+- **ImageCleanupTask**: Docker image cleanup using [docuum](https://github.com/stepchowfun/docuum) with configurable disk threshold
+
+**Configuration Example:**
+```yaml
+scheduler:
+  enabled: true
+  worker_cache_ttl: 3600
+  tasks:
+    - task_class: "rock.admin.scheduler.tasks.image_cleanup_task.ImageCleanupTask"
+      enabled: true
+      interval_seconds: 3600
+      params:
+        threshold: "1T"
+```
+
+**Extensibility:**
+Create custom tasks by extending `BaseTask` and implementing the `run_action(runtime: RemoteSandboxRuntime)` method.
+
+#### Entrypoints
+
+- **NEW**: Batch sandbox status query API (`POST /sandboxes/batch`)
+  - Efficiently retrieve status information for multiple sandboxes in a single request
+  - Accepts `BatchSandboxStatusRequest` with `sandbox_ids` list
+  - Returns `BatchSandboxStatusResponse` containing status details for all requested sandboxes
+  - Supports up to configurable maximum count (default from `batch_get_status_max_count`)
+
+- **NEW**: Sandbox listing and filtering API (`GET /sandboxes`)
+  - Query and filter sandboxes with flexible query parameters
+  - Supports pagination via `page` and `page_size` parameters
+  - Returns `SandboxListResponse` with items, total count, and `has_more` indicator
+  - Enables filtering by sandbox attributes (e.g., deployment type, status, custom metadata)
+  - Maximum page size configurable via `batch_get_status_max_count`
+
+#### Sandbox
+
+- Modify Sandbox log format: use iso 8601 format for timestamp, default time zone is Asia/Shanghai
+- Enrich SandboxInfo: add create_time, start_time, stop_time for metrics
+- Add Billing log when sandbox is closed
+
+---
+
+### Enhancements
+
+#### Performance Optimizations
+- Decouple the `get_status` API logic from Ray, reducing API latency from 1s+ to 100ms+; support dynamically toggling between the new and legacy logic.
+- Sink ray operations from sandbox manager into ray service.
