Selenium Builder v.2.0 has been released with significant improvements, including built-in support for Selenium 2/Webdriver, allowing users to record, edit, and playback test scripts in the new version. The tool now also supports exporting scripts into various programming languages such as Java, Ruby, Python, PHP, Node.js, and C#. Additionally, Selenium Builder introduces a clean JSON-based format for storing scripts, which can be played back by a standalone interpreter. The tool also features plugin architecture, allowing users to extend its functionality with plugins that can be installed and managed directly from the interface. Furthermore, the new release includes support for Sauce Labs integration, GitHub integration, foreign language support, and more.
