Next.js v16.4.6 released with backported bug fixes
Vercel published Next.js v16.4.6 on 2026-11-09. The release backports bug fixes, including pinning Tailwind to 4.3.3 in create-next-app and tests, automatic compression of route handler responses when not already compressed, and Turbopack garbage collection fixes for development.
Why it matters
Builders on Next.js 16 receive patch-level fixes for create-next-app Tailwind setup, route handler response compression, and Turbopack dev memory behavior. The release notes state it does not include all pending canary changes.
Who should care
Next.js developers, teams maintaining Next.js 16 LTS applications, agencies running Next.js sites in development with Turbopack.
