@changed: useContext() -> useNuxtApp() note: any keys that previously exists in useContext() is now moved into useNuxtApp().nuxt2Context, so you can't directly use it from useNuxtApp()
@changes: route (previously in useContext()) is no longer in ref, so you should directly use the value of it, for example:
before: const currentRoute = route.value.name
is now: const currentRoute = route.name
Miscellaneous
$config & this.$config is now separated into 2 types, app and public (which configured in nuxt.config.ts -> publicRuntimeConfig)
so, if you want to use any configs that defined in publicRuntimeConfig you should use $config.public
Don't know why but seems like you don't need to re-import composable file in every files that need it, for example if you have already imported a composable file in /layouts/Layout.vue, then you don't need to re-import it when you want to use it in the child component
Template refs is not working, the value is encapsulated in _setupState
