3.2.0 (2021-08-09)

Compatibility Notes

This release contains no public API breakage. However, there are a few compatibility related notes:

Due to usage of new runtime helpers, code generated by the template compiler in >= 3.2 will not be compatible with runtime < 3.2.

This only affects cases where there is a version mismatch between the compiler and the runtime. The most common case is libraries that ship pre-compiled Vue components. If you are a library author and ship code pre-compiled by Vue >= 3.2, your library will be only compatible Vue >= 3.2.
This release ships TypeScript typings that rely on Template Literal Types and requires TS >= 4.1.

Bug Fixes

compat: update cjs dist file names (#3893) (434ea30)

3.1.0 (2021-06-07)

Features

Migration Build
compiler-core: whitespace handling strategy (dee3d6a)
support component-level compilerOptions when using runtime compiler (ce0bbe0)
config: support configuring runtime compiler via app.config.compilerOptions (091e6d6)
support casting plain element to component via is="vue:xxx" (af9e699)
devtools: improved KeepAlive support (03ae300)
devtools: performance events (f7c54ca)
onServerPrefetch (#3070) (349eb0f)

Performance Improvements

only trigger $attrs update when it has actually changed (5566d39)
compiler: skip unncessary checks when parsing end tag (048ac29)
avoid deopt for props/emits normalization when global mixins are used (51d2be2)

Deprecations

app.config.isCustomElement has been deprecated and should be now nested under app.config.compilerOptions. [Docs]
delimiters component option has been deprecated and should now be nested under the compilerOptions component option. [Docs]
v-is has been deprecated in favor of is="vue:xxx" [Docs]

Minor Breaking Changes

this.$props and the props object passed to setup() now always contain all the keys for declared props, even for props that are absent (4fe4de0). This has always been the behavior in Vue 2 and is therefore considered a fix (see reasoning in #3288). However, this could break Vue 3 code that relied on the keys for prop absence checks. The workaround is to use a Symbol default value for props that need absence checks:
```
const isAbsent = Symbol()

export default {
  props: {
    foo: { default: isAbsent }
  },
  setup(props) {
    if (props.foo === isAbsent) {
      // foo is absent
    }
  }
}
```
optionMergeStrategies functions no longer receive the component instance as the 3rd argument. The argument was technically internal in Vue 2 and only used for generating warnings, and should not be needed in userland code. This removal enables much more efficient caching of option merging.

Code Refactoring

adjust component options merge cache strategy (1e35a86)

Performance Improvements

avoid deopt for props/emits normalization when global mixins are used (51d2be2)

BREAKING CHANGES

optionMergeStrategies functions no longer receive the component instance as the 3rd argument. The argument was technically internal in Vue 2 and only used for generating warnings, and should not be needed in userland code. This removal enables much more efficient caching of option merging.

BREAKING CHANGES

reactivity: Reactivity APIs adjustments:

readonly is now non-tracking if called on plain objects. lock and unlock have been removed. A readonly proxy can no longer be directly mutated. However, it can still wrap an already reactive object and track changes to the source reactive object.
isReactive now only returns true for proxies created by reactive, or a readonly proxy that wraps a reactive proxy.
A new utility isProxy is introduced, which returns true for both reactive or readonly proxies.
markNonReactive has been renamed to markRaw.

Reverts

Revert "feat(reactivity): add effect to public api (#909)" (#961) (9e9d264), closes #909 #961

BREAKING CHANGES

reactivity: markReadonly has been removed.
runtime-dom: Only props starting with on followed by an uppercase letter or a non-letter character are considered event listeners.
runtime-core: this.$emit() and setupContext.emit() no longer return values. For logic that relies on return value of listeners, the listener should be declared as an onXXX prop and be called directly. This still allows the parent component to pass in a handler using v-on, since v-on:foo internally compiles to onFoo.

BREAKING CHANGES

runtime-core: attribute fallthrough behavior has been adjusted according to https://github.com/vuejs/rfcs/pull/154
<portal> has been renamed to <teleport>.

target prop is also renamed to to, so the new usage will be:
```
<Teleport to="#modal-layer" :disabled="isMobile">
  <div class="modal">hello</div>
</Teleport>
```
The primary reason for the renaming is to avoid potential naming conflict with native portals.
asyncComponent: async component error and loading options have been renamed to errorComponent and loadingComponent respectively.
runtime-core: createAsyncComponent has been renamed to defineAsyncComponent for consistency with defineComponent.

runtime-core: adjust attr fallthrough behavior

Updated per pending RFC https://github.com/vuejs/rfcs/pull/137
- Implicit fallthrough now by default only applies for a whitelist of attributes (class, style, event listeners, a11y attributes, and data attributes).
- Fallthrough is now applied regardless of whether the component has
runtime-core: revert setup() result reactive conversion

Revert 6b10f0c & a840e7d. The motivation of the original change was avoiding unnecessary deep conversions, but that can be achieved by explicitly marking values non-reactive via markNonReactive.

Removing the reactive conversion behavior leads to an usability issue in that plain objects containing refs (which is what most composition functions will return), when exposed as a nested property from setup(), will not unwrap the refs in templates. This goes against the "no .value in template" intuition and the only workaround requires users to manually wrap it again with reactive().

So in this commit we are reverting to the previous behavior where objects returned from setup() are implicitly wrapped with reactive() for deep ref unwrapping.

BREAKING CHANGES

directives: custom directive bindings no longer expose instance

This is a rarely used property that creates extra complexity in ensuring it points to the correct instance. From a design perspective, a custom directive should be scoped to the element and data it is bound to and should not have access to the entire instance in the first place.

BREAKING CHANGES

runtime-core: replace watch(fn, options?) with watchEffect

The watch(fn, options?) signature has been replaced by the new watchEffect API, which has the same usage and behavior. watch now only supports the watch(source, cb, options?) signature.
reactivity: reactive arrays no longer unwraps contained refs

When reactive arrays contain refs, especially a mix of refs and plain values, Array prototype methods will fail to function properly - e.g. sort() or reverse() will overwrite the ref's value instead of moving it (see #737).

Ensuring correct behavior for all possible Array methods while retaining the ref unwrapping behavior is exceedingly complicated; In addition, even if Vue handles the built-in methods internally, it would still break when the user attempts to use a 3rd party utility function (e.g. lodash) on a reactive array containing refs.

After this commit, similar to other collection types like Map and Set, Arrays will no longer automatically unwrap contained refs.

The usage of mixed refs and plain values in Arrays should be rare in practice. In cases where this is necessary, the user can create a computed property that performs the unwrapping.

reactivity: better computed tracking (#710) (8874b21)

BREAKING CHANGES

watch: watch behavior has been adjusted.
- When using the watch(source, callback, options?) signature, the callback now fires lazily by default (consistent with 2.x behavior).
  
  Note that the watch(effect, options?) signature is still eager, since it must invoke the effect immediately to collect dependencies.
- The lazy option has been replaced by the opposite immediate option, which defaults to false. (It's ignored when using the effect signature)
- Due to the above changes, the watch option in Options API now behaves exactly the same as 2.x.
- When using the effect signature or { immediate: true }, the initial execution is now performed synchronously instead of deferred until the component is mounted. This is necessary for certain use cases to work properly with async setup() and Suspense.
  
  The side effect of this is the immediate watcher invocation will no longer have access to the mounted DOM. However, the watcher can be initiated inside onMounted to retain previous behavior.

adjust createApp related API signatures (c07751f)
remove implicit reactive() call on renderContext (6b10f0c)

Performance Improvements

ssr: avoid unnecessary async overhead (297282a)

BREAKING CHANGES

object returned from setup() are no longer implicitly passed to reactive().

The renderContext is the object returned by setup() (or a new object if no setup() is present). Before this change, it was implicitly passed to reactive() for ref unwrapping. But this has the side effect of unnecessary deep reactive conversion on properties that should not be made reactive (e.g. computed return values and injected non-reactive objects), and can lead to performance issues.

This change removes the reactive() call and instead performs a shallow ref unwrapping at the render proxy level. The breaking part is when the user returns an object with a plain property from setup(), e.g. return { count: 0 }, this property will no longer trigger updates when mutated by a in-template event handler. Instead, explicit refs are required.

This also means that any objects not explicitly made reactive in setup() will remain non-reactive. This can be desirable when exposing heavy external stateful objects on this.
createApp API has been adjusted.
- createApp() now accepts the root component, and optionally a props object to pass to the root component.
- app.mount() now accepts a single argument (the root container)
- app.unmount() no longer requires arguments.
New behavior looks like the following:
```
const app = createApp(RootComponent)
app.mount('#app')
app.unmount()
```
