GrowthBook 2.5 is a significant update that enhances its feature flagging and A/B testing platform, aiming to streamline experimentation-driven software development. This release introduces Metric Fact Tables for simplified metrics creation, Remote Evaluation Mode for JavaScript and React SDKs to enhance performance and privacy, and SCIM integration for Okta to automate user provisioning. It also includes a Data Pipeline Mode for BigQuery and Snowflake, reducing query costs, and AI-powered copy suggestions in the visual editor for content enhancement. Users can now simulate feature flag rules with User Archetypes and utilize new API endpoints for managing feature flags, while multi-organization deployments accommodate complex business structures with isolated environments. Additional improvements include better experiment velocity graphs, Snowflake query tagging, and enhanced experiment search and stats engine selection.
