2.6 Internal Change: Scoped Slot Function Return Value

This change only affects render function users. If you only use templates, you can ignore this change.

The Problem

In render functions, scoped slots are exposed on this.$scopedSlots as functions. Up until now, calling a scoped slot function can return a single VNode or an Array of VNodes based on what the parent component is passing in. For example, given this component:

const Child = {

export default {
  async mounted() {
    // if an async error is thrown here, it now will get
    // caught by errorCaptured and Vue.config.errorHandler
    this.posts = await api.getPosts()
  }
}

<script type="module">
import Vue from 'https://unpkg.com/vue/dist/vue.esm.browser.js'
  
new Vue({
  // ...
})
</script>
