 # Changelog
 
-## [1.1.1] - 2026-05-05
+## [1.1.2] - 2026-05-05
+- **架构解耦**: 
+  - 正式移除 `log` 包对数据库日志（`DB` 方法及 `DBLog` 结构）的内置支持，推动“日志格式随业务走”的架构对齐。
+  - 导出 `GetCallStacks` 方法，支持外部包捕获符合截断配置的调用栈。
+- **内部优化**: 
+  - `fillBase` 回归私有，强化 `Log(entry)` 的自动填充契约，降低外部摩擦。
 - **体验对齐**:
   - 修复 `viewer.go` 中空错误字符串导致日志类型被跳过显示的 Bug。
   - `Log` 方法集成 `fillBase` 自动补全逻辑，对于直接调用 `Log(entry)` 的自定义日志类型，若未设置时间戳则自动填充元数据，无需手动干预。
