+
+### :star: New Features
+
+#### Composable API
+
+New style API for Vue 3. See the following docs:
+
+- [createI18nComposer](https://github.com/intlify/vue-i18n-next/blob/master/docs/vue-i18n.createi18ncomposer.md)
+- [I18nComposerOptions](https://github.com/intlify/vue-i18n-next/blob/master/docs/vue-i18n.i18ncomposeroptions.md)
+- [I18nComposer](https://github.com/intlify/vue-i18n-next/blob/master/docs/vue-i18n.i18ncomposer.md)
+- [useI18n](https://github.com/intlify/vue-i18n-next/blob/master/docs/vue-i18n.usei18n.md)
+
+
+### :lollipop: Examples
+
+See the [`examples`](https://github.com/intlify/vue-i18n-next/tree/master/examples) directory.
+
+The examples are offered that use the following two API styles:
+
+- composable
+  - new vue-i18n API optimized for Vue 3. details about API
+- legacy
+  - vue-i18n API almost compatible with vue-i18n v8.x
+
+
+### :heavy_exclamation_mark: Known issues
+
+#### :boom: Breaking changes compared to vue-i18n v8.x
+
+- API
+  - The return value of `$t` and `t` methods is **string** only. object and array values ​​are no longer returned.
+  - The return value of `$tc` and `tc` methods is **string** only. object and array values ​​are no longer returned.
+  - `VueI18n` class cannot used with `new`. It can only be used via the `$i18n` property of Vue instance.
+    - In vue-i18n-next, by replacing `new VueI18n` with `createI18n`, you can use existing `VueI18n` options as they are.
+    - See the `examples/legacy` directory.
+  - `VueI18n.prototype.getChoiceIndex`
+    - -> Legacy API style: `pluralizationRules` option of `createI18n` factory function (like `new VueI18n(...)`)
+    - -> Compsable API style: `pluralRules` option of `createI18nComposer` facatory function
+  - `VueI18n.version` -> `import { VERSION } from 'vue-i18n'`
+  - `VueI18n.availabilities` -> `import { availabilities } from 'vue-i18n'`
+  - See the details [here](https://github.com/intlify/vue-i18n-next/blob/master/docs/vue-i18n.md)
