 # Changelog
+
+## [0.48.6-public] - 2024-07-17
+
+### Added
+- **Serializable Support**:
+  - Key data types like `ArrayRecord`, `Column`, `TableSchema`, and `TypeInfo` now support serialization and deserialization, enabling caching and inter-process communication.
+- **Predicate Pushdown**:
+  - Introduced `Attribute` type predicates to specify column names.
+
+### Changed
+- **Tunnel Interface Refactoring**:
+  - Refactored Tunnel-related interfaces to include seamless retry logic, greatly enhancing stability and robustness.
+  - Removed `TunnelRetryStrategy` and `ConfigurationImpl` classes, which are now replaced by `TunnelRetryHandler` and `Configuration` respectively.
+
+### Improve
+- **SQLExecutor Optimization**:
+  - Improved performance when executing offline SQL jobs through the `SQLExecutor` interface, reducing one network request per job to fetch results, thereby decreasing end-to-end latency.
+
+### Fixed
+- **Decimal Read in Table.read**:
+  - Fixed issue where trailing zeroes in the `decimal` type were not as expected in the `Table.read` interface.
+
+
 ## [0.48.5-public] - 2024-06-17
 ### Added
 - Added the `getPartitionSpecs` method to the `Table` interface. Compared to the `getPartitions` method, this method does not require fetching detailed partition information, resulting in faster execution.

 # 更新日志
 
+## [0.48.6-public] - 2024-07-17
+
+### 新增
+- **支持序列化**：
+  - 主要数据类型如 `ArrayRecord`、`Column`、`TableSchema` 和 `TypeInfo` 现在支持序列化和反序列化，能够进行缓存和进程间通信。
+- **谓词下推**：
+  - 新增 `Attribute` 类型的谓词，用于指定列名。
+
+### 变更
+- **Tunnel 接口重构**：
+  - 重构了 Tunnel 相关接口，加入了无感知的重试逻辑，大大增强了稳定性和鲁棒性。
+  - 删除了 `TunnelRetryStrategy` 和 `ConfigurationImpl` 类，分别被 `TunnelRetryHandler` 和 `Configuration` 所取代。
+
+### 优化
+- **SQLExecutor 优化**：
+  - 在使用 `SQLExecutor` 接口执行离线 SQL 作业时进行优化，减少每个作业获取结果时的一次网络请求，从而减少端到端延时。
+
+### 修复
+- **Table.read Decimal 读取**：
+  - 修复了 `Table.read` 接口在读取 `decimal` 类型时，后面补零不符合预期的问题。
