Vercel consolidated eight PRs of error messaging improvements into a single merge while simultaneously landing TanStack Start support across the entire DevKit stack.

The friendlier-errors consolidation [1] finally unblocks work that stalled for months—eight separate PRs folded into one atomic change that makes Workflow failures readable again. In parallel, TanStack Start is now a first-class citizen: the workbench [2] landed with full e2e coverage, a getting-started guide is live, and the examples repo [6] shipped a reference implementation that boots cleanly. The framework grid on the homepage lost its "coming soon" badge. Under the hood, a nasty race condition in world-local [3] got fixed—concurrent invocations with identical correlationIds were silently overwriting each other on step_created and wait_created events. That's the kind of bug that haunts you in production. Tarball hosting [4] spun out of docs into its own deployment unit, which means faster builds and cleaner separation. On the Vercel platform side, the Next.js adapter bumped to the latest [5], keeping the integration current with upstream changes.
