+## 3.0.0 / 2023-10-18
+
+### refactor / chore
+
+- upgrade dependencies
+
+# BREAKING CHANGE
+
+Remove some unused/unneeded code which drops support for older browser versions. Results in slightly decreased bundle size.
+
+- remove unneeded polyfill for translateStyle - [browser support since 2017](https://caniuse.com/?search=transforms)
+- remove unneeded polyfill for `Number.isFinite` - [browser support since 2015](https://caniuse.com/?search=Number.isFinite) AND polyfilled by babel/core-js
+
+## 2.0.5 / 2023-10-10
+
+### fix
+
+- Check if `requestAnimationFrame` is defined in shouldUpdate
+
+## 2.0.4 / 2023-09-12

+
+## 2.0.3 / 2023-05-08

+
+## 2.0.2 / 2023-02-23

+### chore
+
+- upgrade `fast-equals` to latest. No breaking changes - see https://github.com/planttheidea/fast-equals/blob/master/CHANGELOG.md

+# react-smooth
+
+react-smooth is a animation library work on React.
+
+[![npm version](https://badge.fury.io/js/react-smooth.png)](https://badge.fury.io/js/react-smooth)
+[![build status](https://travis-ci.org/recharts/react-smooth.svg)](https://travis-ci.org/recharts/react-smooth)
+[![npm downloads](https://img.shields.io/npm/dt/react-smooth.svg?style=flat-square)](https://www.npmjs.com/package/react-smooth)
+[![Gitter](https://badges.gitter.im/recharts/react-smooth.svg)](https://gitter.im/recharts/react-smooth?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge)
+
+## install
+```
+npm install --save react-smooth
+```
+
+## Usage
+simple animation
+
+```jsx
+<Animate to="0" from="1" attributeName="opacity">
+  <div />
+</Animate>
+```
+steps animation
+
+```jsx
+const steps = [{
+  style: {
+    opacity: 0,
+  },
+  duration: 400,
+}, {
+  style: {
+    opacity: 1,
+    transform: 'translate(0, 0)',
+  },
+  duration: 1000,
+}, {
+  style: {
+    transform: 'translate(100px, 100px)',
+  },
+  duration: 1200,
+}];
+
+<Animate steps={steps}>
+  <div />
+</Animate>
+```
+children can be a function
+
+```jsx
+<Animate from={{ opacity: 0 }}
+  to={{ opacity: 1 }}
+  easing="ease-in"
+  >
+  {
+    ({ opacity }) => <div style={{ opacity }}></div>
+  }
+</Animate>
+```
+
+you can configure js timing function
+
+```js
+const easing = configureBezier(0.1, 0.1, 0.5, 0.8);
+const easing = configureSpring({ stiff: 170, damping: 20 });
+```
+
+group animation
+
+```jsx
+const appear = {
+  from: 0,
+  to: 1,
+  attributeName: 'opacity',
+};
+
+const leave = {
+  steps: [{
+    style: {
+      transform: 'translateX(0)',
+    },
+  }, {
+    duration: 1000,
+    style: {
+      transform: 'translateX(300)',
+      height: 50,
+    },
+  }, {
+    duration: 2000,
+    style: {
+      height: 0,
+    },
+  }]
+}
+
+<AnimateGroup appear={appear} leave={leave}>
+  { list }
+</AnimateGroup>
+
+/*
+ *  @description: add compatible prefix in style
+ *
+ *  style = { transform: xxx, ...others };
+ *
+ *  translatedStyle = {
+ *    WebkitTransform: xxx,
