We’re very happy to announce the release of Selenium 4.20.0 for Javascript, Ruby, Python, .NET, Java and the Grid! Links to everything can be found on our downloads page.

Highlights

  • Chrome DevTools support is now: v122, v123, and v124 (Firefox still uses v85 for all versions)
  • Selenium has at least 2.3M active users in the last 30 days. 500k more than last month!
  • Java and JavaScript keep adding more WebDriver BiDi features.
  • .NET C# and JavaScript now publish nightly builds to GitHub packages.
  • Nightly packages are tested daily with the examples from the Selenium documentation.
  • The code used to invoke Selenium Manager has been refactored in all languages, making it easier to maintain and improve.
