 # 变更记录 - @go/db
 
-## [1.3.1] - 2026-05-13
+## [1.0.11] - 2026-05-13
+- **基础设施对齐**:
+    - 移除 `encoding/json` 原生依赖，全面切换至 `apigo.cc/go/cast.UnmarshalJSON` 以增强类型兼容性。
+    - 移除测试代码中对 `os.Remove` 的直接调用，统一切换至 `apigo.cc/go/file.Remove` 以支持隔离文件系统。
+- **稳定性增强**:
+    - 验证并更新了测试用例，确保在 Go 1.25.0 环境下的执行稳定性。
+    - 更新 `TEST.md` 性能基准，反映基础设施对齐后的最新指标。
+
+## [1.0.10] - 2026-05-10
 - **功能增强**:
     - 全面支持“复杂标识符”：改进了 `LIKE` 拦截逻辑中的正则表达式，支持带引号（`` ` ``, `"`, `'`, `[]`）和特殊字符（如 `-`）的表名与字段名。
     - 优化 `cleanIdentifier`：能够更精准地剥离多段式标识符（如 `table.column`）中的包装引号。
