The Vue team shipped [email protected] on 11 September 2026, pushing the biggest release since Vue 3 toward the finish line: the long-awaited Vapor Mode.
Rendering without a virtual DOM
Vapor Mode is a new compilation strategy that drops the virtual DOM entirely for opted-in components. Instead of a diffing layer, the compiler turns templates straight into imperative DOM operations, so a state change touches only the nodes that actually change. Independent benchmarks put Vue on par with Solid and Svelte 5. The mode is fully opt-in and can be adopted gradually alongside classic components.
New reactivity and steadier hydration
Under the hood, the reactivity system has been rebuilt on alien-signals, cutting memory use and improving speed. Recent release candidates focused on reliability: hydration fixes for multi-root components, async setup and slots, plus cleaner interop between Vapor and virtual-DOM components.
Why it matters for developers
With rc.8 the feature set is frozen and a stable 3.6.0 is imminent. Teams running homelab dashboards or self-hosted front ends on Vue can now trial Vapor Mode in individual views without rewriting the whole app.
