Hutool 39 New

import cn.hutool.core.io.FileUtil;

Need to mention that in the guide. Also, if there's a new way to handle system properties or environment variables, that could be part of the new features.

Map<String, Object> map = new HashMap<>(); map.put("user.name", "Alice"); map.put("user.age", 30); hutool 39 new

Need to ensure the examples are syntactically correct. For instance, using the new DateUtil method:

import cn.hutool.http.HttpUtil;

Examples are crucial. For each new feature, a short code example. Make sure the code is correct and shows practical applications. For instance, using a new method in BeanUtils to convert a Map to a Bean with nested properties.

I should also mention migration from previous versions if there are breaking changes. But since the user didn't specify, I can note that it's a backward-compatible update with minimal breaking changes, and provide any necessary tips for upgrading. import cn

This is a hypothetical example if they added a parseIso8601 method.
