This is the full Vue 3.6 beta reference, and you'll want it loaded whenever you touch a .vue file or anything importing from the vue package. It covers the latest APIs including experimental Vapor Mode (the new no-VDOM compiler), the stable Composition API helpers like useTemplateRef and useId from 3.5, and all the breaking changes since 3.3. The best practices section is solid on performance patterns like shallow reactivity for large data and computed stability tricks. If you're working with Vue SSR, the lazy hydration strategies alone justify keeping this active. The API changelog is thorough enough that you won't need to context switch to the docs for most questions about what changed between versions.
