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.

3.1.1 (2021-06-07)

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.
