Selenium 4.0 Alpha Release Updates

May 7, 2019

The wait is finally over, and the Selenium 4.0 Alpha release has been launched.

The wonderful comments from Simon Mavi Stewart about Selenium 4.0 alpha release as below:

The Selenium team has not yet announced it, but Selenium 4 Alpha is available to download at the MVN Repository. The below dependency should be added to pom.xml to get the alpha version.
From the word Alpha, we have come to know that there is a high chance it might not be stable enough. The current Selenium 4 is in an Alpha version, so it is not recommended to use for testing. We can start to use once it changes from Alpha to Beta.

Selenium 4 Alpha has undergone many significant changes, but it won’t impact your existing automation scripts.
