v4.1.0

Release Highlights

Holdouts
Holdout experiments measure the long-term impact of features by maintaining a control group that doesn't receive new functionality. While most users experience your latest features and improvements, a small percentage remains on the original version, providing a baseline to measure cumulative effects over time.

Experiment Dashboards
Experiment Dashboards let you create tailored views of an experiment. Highlight key insights, add context, and share a clear story with your team. Dashboards are available for all Enterprise customers. We have a lot planned for this in the future, so stay tuned!

Vercel Native Integration
We're excited to announce that GrowthBook is now available as a native integration in the Experimentation category on the Vercel Marketplace! This integration makes it easier than ever to add feature flagging and A/B testing to your Vercel projects, with streamlined setup, unified billing, and ultra-low latency performance.

AI Features
This release deeply integrates AI to help accelerate your workflows within GrowthBook. Auto-summarize experiment results, get help writing SQL, improve hypotheses, and detect similar past experiments, and more. These features are available to everyone, even self-hosted (just supply an OpenAI key).

Pre-computed Dimensions
You can now pick a set of key experiment dimensions and pre-compute them along with the main experiment results. This allows for more efficient database queries, and instant dimension breakdowns in the UI.

FerretDB Support
FerretDB is a MongoDB-compatible database that is open source and free to use. It serves as a drop-in replacement for MongoDB, converting MongoDB wire protocol queries to SQL and using PostgreSQL as its backend storage engine.

Sanity CMS Integration
Sanity is a real-time content backend for all your text and assets. You can now use GrowthBook feature flags to seamlessly test different content variations within Sanity.

MCP Updates
We've updated our MCP Server to allow creating experiments directly from your AI tool of choice without needing to context switch to GrowthBook. This change unlocks a bunch of new exciting workflows and we can't wait to see how you use it!

New Experiment Results Tooltip
We've completely redesigned the tooltip when mousing over experiment results. The new design provides more context and insights at a glance, making it easier to understand the impact of your experiments.

SQL Auto-Complete
We've added context-aware SQL auto-complete suggestions for table and column names to help you write queries faster and with fewer errors.

Official Segments and Dimensions
You can now mark specific segments and user dimensions as Official via the GrowthBook API. This will give them a little badge in the UI and lock down editing to prevent unwanted changes. Use this to differentiate important segments and dimensions from ad-hoc or exploratory ones.

Self-Hosting Improvements
For anyone self-hosting GrowthBook, we've greatly improved observability and customization. We now support full monitoring and tracing of all background jobs, plus distributed tracing within the Python stats engine. We also added a number of new env vars to more easily split the GrowthBook monolith into microservices for those that need extra scalability.

Full Changelog: v4.0.0...v4.1.0

v4.0.0

Release Highlights

GrowthBook MCP Server
AI tools like Cursor can now interact with GrowthBook via our new MCP server. Create feature flags, check the status of running experiments, clean up stale code, and more.

Safer Rollouts
Building upon our Safe Rollouts release last version, we added gradual traffic ramp up, auto rollback, a smart update schedule, and a time series view of results. All of these combine to add even more safety around your feature releases.

Decision Criteria
You can now customize the shipping recommendation logic for experiments. Choose from a “Clear Signals” model, a “Do No Harm” model, or define your own from scratch.

Search Filters
We’ve revamped the search experience within GrowthBook to make it easier to find feature flags, metrics, and experiments. Easily filter by project, owner, tag, type, and more.

Insights Section
We added a brand new left nav section called “Insights” with a bunch of tools to help you learn from your past experiments.

• The Dashboard shows velocity, win rate, and scaled metric impact by project.
• Learnings is a searchable knowledge base of all of your completed experiments.
• The Experiment Timeline shows when experiments were running and how they overlapped with each other.
• Metric Effects lists the experiments that had the biggest impact on a specific metric.
• Metric Correlations let you see how two metrics move in relation to each other.

SQL Explorer
We launched a lightweight SQL console and BI tool to explore and visualize your data directly within GrowthBook, without needing to switch to another platform like Looker.

Managed Warehouse
GrowthBook Cloud now offers a fully managed ClickHouse database that is deeply integrated with the product. It’s the fastest way to start collecting data and running experiments on GrowthBook. You still get raw SQL access and all the benefits of a warehouse native product, without the setup and maintenance cost.

Feature Flag Usage
See analytics about how your feature flags are being evaluated in your app in real time. This is built on top of the new Managed Warehouse on GrowthBook Cloud and is a game changer for debugging and QA.

Vercel Flags SDK
GrowthBook now has an official provider for the Vercel Flags SDK. This is now the easiest way to add server-side feature flags to any Next.js project. We have an even deeper Vercel integration coming soon to make this experience even more seamless.

Official Framer Plugin
You can now easily run GrowthBook experiments inside of your Framer projects. Assign visitors to different versions of your design (like layouts, headlines, or calls to action), track results, and confidently choose the best experience for your audience.

Personalized Landing Page
There’s a new landing page when you first log into GrowthBook. Quickly see any features or experiments that need your attention, pick up where you left off, and learn about advanced GrowthBook functionality to get the most out of the platform.

Experimentation Left Nav
There’s a new “Experimentation” section in the left nav. Experiments and Bandits now live within this section, along with our Power Calculator, Experiment Templates, and Namespaces. We’ll be expanding this section soon with Holdouts and more, so stay tuned!

REST API Updates

• Filter the listFeatures endpoint by clientKey
• Support partial rule updates in the putFeature endpoint
• New Queries endpoint to retrieve raw SQL queries and results from an experiment
• Added Custom Field support to feature and experiment endpoints
• New endpoints for getting feature code refs
• New endpoint to revert a feature to a specific revision

Performance Improvements
We’ve drastically improved the CPU and memory usage when self-hosting GrowthBook at scale. On GrowthBook Cloud, we’ve seen a roughly 50% reduction during peak load, leading to lower latency and virtually eliminating container failures in production.
