The development of Selenium 3 is officially discontinued. The next major version of Selenium 4 is being prepared for release. New commands that have been recently added to the W3C WebDriver standard will appear. A lot of legacy code will be removed, including the driver for “old” versions of Firefox. But the main changes will take place in Selenium Server and Selenium Grid. In short, the server will be completely redesigned, the new implementation is written from scratch. Yes, communication protocols will remain old, but the internal device will change beyond recognition. In particular, if earlier Selenium Grid consisted of two types of nodes (hub and end nodes), the new version will have four types of nodes. In my report, I will try to explain why we changed everything, who will get better from this, what will be the possibilities for customizing the grid in the new version and how to migrate from the old version to the new one.
