GrowthBook version 0.8.0 introduces significant updates, including a complete redesign for improved user experience, greatly accelerated statistical analyses, and enhanced dimensional analysis features. The new design features updated navigation, colors, and layout, while performance improvements have reduced analysis processing times by optimizing the interaction between the Typescript API and Python statistics engine. Dimensional analysis now includes automatic dimensionality reduction for high-cardinality dimensions, maintaining the top 20 values for clear insights and grouping other values to minimize false positives. The Jupyter Notebook Export has been improved to include detailed dimension breakdowns with additional data columns, requiring the latest gbstats version from PyPi. Additionally, mutually exclusive experiment support has been added through namespaces in the JS and React SDKs, preventing conflicts by allocating users into non-overlapping bucket ranges for simultaneous experiments, allowing for enhanced test velocity and segmentation. The update also incorporates various other enhancements and bug fixes.
