+# [4.0.0](https://github.com/vuejs/vuex/compare/v4.0.0-rc.2...v4.0.0) (2021-02-02)
+
+This is the official Vuex 4 release.
+
+The focus for Vuex 4 is compatibility. Vuex 4 supports Vue 3, and it provides the exact same API as Vuex 3, so users can reuse their existing Vuex code with Vue 3.
+
+There are a few breaking changes described in a later section, so please check them out.
+
+You can find basic usage with both Option and Composition API in the `example` directory.
+
+It's still released under `next` tag in NPM package as same as Vue 3. We're planning to remove `next` tag once Vue 3 is ready to remove it.
+
+There have been a lot of contribution to make Vuex 4 stable. Thank you all for your very much appreciated help. It wouldn't have been possible without this wonderful Vue community!

+
+## Breaking changes
+
+### Installation process has changed
+
+To align with the new Vue 3 initialization process, the installation process of Vuex has changed.
+
+To create a new store instance, users are now encouraged to use the newly introduced `createStore` function.
+
+```js
+import { createStore } from 'vuex'
+
+export const store = createStore({
+  state() {
+    return {
+      count: 1
+    }
+  }
+})
+```
+
+> Whilst this is not technically a breaking change, you may still use the `new Store(...)` syntax, we recommend this approach to align with Vue 3 and Vue Router Next.
+
+To install Vuex to a Vue instance, pass the store instance instead of Vuex.
+
+```js
+import { createApp } from 'vue'
+import { store } from './store'
+import App from './App.vue'
+
+const app = createApp(App)
+
+app.use(store)
+
+app.mount('#app')
+```
+
+### Bundles are now aligned with Vue 3
+
+The following bundles are generated to align with Vue 3 bundles:
+
+- `vuex.global(.prod).js`
+  - For direct use with `<script src="...">` in the browser. Exposes the Vuex global.
+  - Global build is built as IIFE, and not UMD, and is only meant for direct use with `<script src="...">`.
+  - Contains hard-coded prod/dev branches and the prod build is pre-minified. Use the `.prod.js` files for production.
+- `vuex.esm-browser(.prod).js`
+  - For use with native ES module imports (including module supporting browsers via `<script type="module">`.
+- `vuex.esm-bundler.js`
+  - For use with bundlers such as `webpack`, `rollup` and `parcel`.
+  - Leaves prod/dev branches with `process.env.NODE_ENV` guards (must be replaced by bundler).
+  - Does not ship minified builds (to be done together with the rest of the code after bundling).
+- `vuex.cjs.js`
+  - For use in Node.js server-side rendering with `require()`.
+
+### Typings for `ComponentCustomProperties`
+
+Vuex 4 removes its global typings for `this.$store` within Vue Component to solve [issue #994](https://github.com/vuejs/vuex/issues/994). When used with TypeScript, you must declare your own module augmentation.
+
+Place the following code in your project to allow `this.$store` to be typed correctly:
+
+```ts
+// vuex-shim.d.ts
+
+import { ComponentCustomProperties } from 'vue'
+import { Store } from 'vuex'
+
+declare module '@vue/runtime-core' {
+  // Declare your own store states.
+  interface State {
+    count: number
+  }
+
+  interface ComponentCustomProperties {
+    $store: Store<State>
+  }
+}
+```
+
+### `createLogger` function is exported from the core module
+
+In Vuex 3, `createLogger` function was exported from `vuex/dist/logger` but it's now included in the core package. You should import the function directly from `vuex` package.
+
+```js
+import { createLogger } from 'vuex'
+```
+
+### Bug Fixes Included Since 4.0.0-rc.2
+
+* export missing `storeKey` ([4ab2947](https://github.com/vuejs/vuex/commit/4ab294793a2c20ea6040f01f316618682df61fff))
+* fix tree shaking notworking in webpack bundle ([#1906](https://github.com/vuejs/vuex/issues/1906)) ([#1907](https://github.com/vuejs/vuex/issues/1907)) ([aeddf7a](https://github.com/vuejs/vuex/commit/aeddf7a7c618eda7f316f8a6ace8d21eb96c29ff))
