Selenium 4.0 and W3C: What You Need to Know
summary
Selenium 4 implements the W3C WebDriver standard so most tests are 90% drop‑in change — update the library, switch to the W3C capability keys (platformName, browserName, browserVersion or vendor:options), and use ChromeOptions/immutable capabilities. The JSON wire protocol is being phased out (JSON Wire Protocol removed), leaving legacy users potentially pinned to Chrome 72 until they migrate. Selenium Grid modernizes for Docker/Kubernetes, merging hub and node, Selenium IDE adds smart locators and plugins, and Appium already targets the new protocol.
