Next.js 16 changed revalidateTag to take a cacheLife profile as a second argument for stale while revalidate behavior, for example revalidateTag('posts', 'max'). The single argument form is deprecated. A new updateTag gives read your writes semantics inside a Server Action. A new refresh call updates uncached data only.
