ROS 2 Humble Hawksbill 正式发布啦

Humble Hawksbill 是一个长期支持 (LTS) 版本，将一直支持到 2027 年 5 月。它是 Ubuntu 22.04 (Jammy Jellyfish) 上的第一个 ROS 2 版本。此版本有两个 Tier 1 操作系统：Ubuntu 22.04 Jammy Jellyfish（arm64 和 amd64 架构）和 Windows 10。如果是 ROS 新手，官方建议使用 Tier 1 操作系统进行试用。

那么名字里有什么？“humble ”是指“以尊重的精神反思、表达或提供”，以及hawksbill 是一种遍布世界各地的海龟。Hawksbill 海龟因其标志性的喙而很容易识别。官方在社区的帮助下选择了这个名字。

Humble 有许多新功能。这很难选择，但这里有一些官方最赞的：

• 类型适配：在 rclcpp 中，可以使用自定义数据结构并将它们隐式转换为通过 ROS 网络发送，或者如果使用进程内通信则直接传递。这对于处理复杂的数据结构（如图像）很方便。
• launch_pytest：一个 pytest 插件，用于在 Python 中编写测试。
• 可组合节点的前端支持：现在可以在启动文件中指定可组合节点。
• 内容过滤主题：订阅者可以过滤想要查看的消息类型。
