Hutool 39 New ((full))

5.8.39 为豆包和 Grok 模型新增了 ，并支持豆包模型通过特定参数进行视频生成。这意味着 Hutool 统一 API 的应用范围从单纯的文本对话扩展到了多模态生成领域，开发者无需针对不同模型编写差异化代码。

Below is a complete, scannable blog post covering this hypothetical release. 🚀 Announcing Hutool 39: Making Java Even Sweeter!

Replaces long, boilerplate Java code with single-line static methods. Forward Thinking:

import cn.hutool.core.date.DateUtil;

：修复了 NumberUtil.isNumber 方法对以 "L" 结尾的数值（如长整型字面量）判断不准确的问题。

// AES-GCM encryption var aes = new AesGcm("1234567890123456".getBytes()); var encrypted = aes.encrypt("Secret".getBytes());

to highlight a specific module of Hutool, or should we adjust it to reflect an actual current version like hutool/README-EN.md at v5-master - GitHub

<dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>5.8.0</version> </dependency>

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