3.2.0 (2021-08-09)
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.

-
this.$props
and theprops
object passed tosetup()
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.

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

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.

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 theeffect
immediately to collect dependencies. -
The
lazy
option has been replaced by the oppositeimmediate
option, which defaults tofalse
. (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 withasync 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.

- ssr: avoid unnecessary async overhead (297282a)
-
object returned from
setup()
are no longer implicitly passed toreactive()
.The renderContext is the object returned by
setup()
(or a new object if no setup() is present). Before this change, it was implicitly passed toreactive()
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 fromsetup()
, 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 onthis
. -
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()
