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.
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. hutool 39 new
Then, best practices: How to integrate these new features into codebase, performance considerations, avoiding common pitfalls. I should also mention migration from previous versions
This is a hypothetical example if they added a parseIso8601 method. Also, if there's a new way to handle
import cn.hutool.http.HttpUtil;
I should outline the guide in sections. The structure could include an introduction to Hutool, new features overview, detailed examples, best practices, and troubleshooting tips. Each new feature section should explain what's new, how to use it, and maybe code examples.
