Appendix A. What’s New in Selenium 4

This appendix provides a summary of the novelties available in Selenium 4. The aim of this content is twofold. First, it enumerates the new features in the core components of the Selenium suite (i.e., WebDriver, Driver, and IDE), providing a link to the book chapter that explains each aspect. In addition, this appendix describes other aspects of the Selenium project that changed with Selenium 4, such as documentation and governance. The second objective is to identify the deprecated parts and the corresponding new features when migrating from Selenium 3 to 4.
