Hutool 39 New Apr 2026

Check for other possible features. Maybe they improved the HttpUtil for asynchronous requests or better error handling. Or added new data structure utilities, like a custom List implementation. hutool 39 new

DateTool might now support ISO 8601 formatting more easily, or have better handling of time zones. BeanUtil could have more efficient copying or handling of null values. Maybe new methods in StringUtil for string manipulation. import cn

Another thought: Hutool often adds more stream-like APIs, simplifying collections. Maybe 3.9 introduced more functional programming features. Or maybe a new Date/Time tool that's more robust. Also, perhaps better support for Java 17 features if the version aligns with that. hutool 39 new
