Changelog

Copy visual context from Vercel Toolbar comments directly to agents. Streamlines feedback-to-code workflow with deployment details and component data.

Workflow 4.1 Beta now stores every state change as an event and reconstructs workflow state by replaying them, so failures can be recovered.

Vercel now detects and deploys Koa, an expressive HTTP middleware framework to make web applications and APIs more enjoyable to write.

Python versions 3.13 and 3.14 are now available for use in Vercel Builds and Vercel Functions. Python 3.14 is the new default version for new projects and deployments.

Vercel Sandbox is now GA, providing isolated Linux VMs for safely executing untrusted code. Run AI agent output, user uploads, and third-party code without exposing production systems.

Cubic joins the Vercel Agents Marketplace, offering teams an AI code reviewer with full codebase context, unified billing, and automated fixes.

AssistLoop is now available in the Vercel Marketplace, making it easy to add AI-powered customer support to Next.js apps deployed on Vercel.

Next.js now supports a custom deploymentId in next.config.js, enabling Skew Protection for vercel deploy --prebuilt workflows. Set your own deployment ID using a git SHA or timestamp to maintain version consistency across prebuilt deployments.
