Release Notes

October brings Tusk Drift closer to full public beta.

Our API test automation product now has comprehensive instrumentations for modern software enginering teams. Drift SDK now supports Next.js apps and instruments MySQL, Redis, Firestore, and gRPC, among other commonly-used packages.

We've also added AI-powered deviation analysis to our Cloud offering to help developers identify unintended API behavior changes and get suggested fixes. You can play around with the product in a GitHub Codespace in our public repo.

On the unit test generation side (Tusk Tester), we've introduced a new agentic workflow with coverage-guided testing, and refreshed our model selection. These improvements make Tusk smarter, 2x faster, and more adaptable to large repos––whether web or mobile.
