# December 2025 Changelog

Marcel Tan

Co-Founder & CEO

## Release Notes

December brought the debut of our [AI Trace Assistant](/content/third-party-integration-testing/index.html), a debugging companion that has contextual understanding of your Tusk Drift observability data. Go beyond Sentry-level observability by drilling into request _and_ response bodies.

We also shipped CoverBot support for Java/Kotlin repos and made reliability improvements to Tusk Drift's deviation analysis and test suite maintenance.

The [Node.js SDK](https://github.com/Use-Tusk/drift-node-sdk) now has Turbopack support for Next.js, while the Tusk Drift CLI has an onboarding agent that installs and initializes the SDK with a single command. We've given the CLI secure replay functionality that runs all test operations in a [local sandbox](https://github.com/Use-Tusk/fence) to prevent unintended external requests.

Not a bad way to close out 2025.
