How To Upgrade to Selenium 4

The Selenium team has upgraded to version 4 with several changes aimed at improving performance and reducing the need for custom functionalities in testing frameworks. The upgrade process is expected to be relatively painless, especially for users of officially supported languages (Ruby, JavaScript, C#, Python, and Java). However, some deprecated methods may cause issues, particularly if custom code has been built around them. Users are advised to check for updates on the Sauce Labs platform configurator, which provides more combinations and examples for upgrading dependencies and using new features. Key changes include removing support for legacy protocol, replacing capabilities with W3C WebDriver standard, and introducing changes in waits and timeouts. Potential issues that may arise during or after the upgrade process have been identified, along with suggested fixes to mitigate these problems.
