How is Selenium 4 different from Selenium 3?

Selenium 4 brings significant upgrades over Selenium 3, enhancing automation testing with better features and improved performance. One key difference is the WebDriver BiDi APIs, enabling better browser interaction. Selenium 4 also introduces relative locators, making element identification easier. Unlike Selenium 3, the new version offers improved grid architecture for better test distribution. Another major upgrade is enhanced native Chrome DevTools Protocol (CDP) support, providing better debugging options. If you're learning through a Selenium course online for beginners, mastering Selenium 4 is crucial for modern automation testing. Upgrading from Selenium 3 to Selenium 4 ensures better efficiency and compatibility.
