GrowthBook has released version 1.0, introducing significant enhancements such as feature flagging and a Chrome DevTools extension, aimed at improving productivity and experimentation capabilities. Feature flagging allows for advanced segmentation and gradual rollouts in A/B testing, now available for Javascript and React SDKs, with further compatibility expected soon. The new Chrome DevTools extension simplifies the testing of different site variations directly within the browser. Additionally, the update enhances the accessibility and management of experiment reports through a dedicated "My Reports" page and enables easier experiment imports directly from the Experiments page. The platform now also includes automatic detection of users exposed to multiple variations in experiments, custom SSL certificate support for Postgres/Redshift, and support for custom delimiters in Google Analytics, alongside numerous other improvements and bug fixes.
