selenium v4.12正式版本发布！速看需要了解的内容！

Posted 2023-02-27

参考技术A 目前selenium的最新版本是v4.1.2（截止到2022年3月7日），看了一下v4.0.0到v4.1.2的升级变化，发现selenium4正式版与 rc版本相比，核心功能并没有发生变化，主要变化的内容总结出以下两点：

1. 对CDP协议高版本的不断支持,关于cdp协议，可以参考文章

使用ChromeDevTools协议编写自己的ChromeDriver

2. Selenium Grid的bug修复 以及稳定性的提升

备注：关于v4.1.2中新增的功能Add new desktop cast command for Chromium，查了一下就是chrome的投屏功能，涉及的自动化测试场景应该非常有限。

如果大家想要了解Selenium4.0的重要功能变化情况，可以看一下我之前写的文章：
