# 支持新的日志等级 FATAL

该版本新增了一个日志等级 `FATAL` 和其对应的打印函数 `Fatal`，签名如下：

```go
func Fatal(message string, args ...any)
```



`FATAL` 记录致命信息，代表目前最高等级的日志（大于先前版本的 `ERROR`），默认情况下，输出到标准错误。在加入 `FATAL` 之后，日志等级排序如下（从低到高）：

1.  `VERBOSE`
2.  `DEBUG`
3.  `INFO`
4.  `WARN`
5.  `ERROR`
6.  `FATAL`





# New Log Level ---- FATAL

This version has added a new log level `VERBOSE` and its corresponding print function `Verbose`, with the following signature:

```
func Fatal(message string, args ...any)
```



`FATAL` is used to record fatal messages, representing the highest-level log currently (with a priority higher than the `ERROR` level in previous versions). By default, it is output to standard error. After the introduction of the `FATAL` level, the hierarchy of log levels (from lowest to highest) is as follows:

1.  `VERBOSE`
2.  `DEBUG`
3.  `INFO`
4.  `WARN`
5.  `ERROR`
6.  `FATAL`
