API Changes

This section documents version-specific API changes — prioritize recent major/minor releases.

• NEW: createVaporApp() (experimental) — new in v3.6, creates a Vapor-mode app instance without pulling in the Virtual DOM runtime; use createApp() for standard VDOM apps source

• NEW: vaporInteropPlugin (experimental) — new in v3.6, install into a VDOM createApp() instance to allow Vapor components inside VDOM trees; without it, Vapor SFCs cannot be used in VDOM apps source

• NEW: <script setup vapor> attribute (experimental) — new in v3.6, opts an SFC into Vapor Mode compilation; only works with <script setup>; does not support Options API, app.config.globalProperties, or getCurrentInstance() source

• NEW: useTemplateRef(key) — new in v3.5, preferred replacement for plain ref variable names matching ref="key" attributes; supports dynamic string IDs at runtime unlike the old static-only pattern source

• NEW: useId() — new in v3.5, generates stable unique IDs per component instance guaranteed to match between SSR and client hydration; replaces manual ID management for form/accessibility attributes source

• NEW: onWatcherCleanup(fn) — new in v3.5, registers a cleanup callback inside a watch or watchEffect callback; replaces the onCleanup parameter pattern and can be called from nested functions source
