   - 添加了 `get_logger_from_old`
     - 用于从现有 logger 中获取一个新的 logger
 - 现在 `info` 级别的默认颜色更白了 (255, 255, 255)
+- `Logger`
+  - 添加了 `default_tag` 属性 (已经在 `0.3.8` 中添加)
+    - 用于设置默认的 tag
+    - 默认为 `None` (无默认 tag)
+    - 可以通过 `logger.tag = "tag"` 来设置
+    - 或者 `logger.set_tag("tag")` 来设置
+      - 可以链式调用
+      - 类似
+      - `self.logger = config.get_logger("root").set_tag("tag")`
+    - 也可以通过 `logger.tag = None` 来取消默认 tag
+    - 或者 `logger.clear_tag()` 来清除默认 tag
