#### How to migrate :

##### Re-build your CSS with the new version of the library.

##### If you use a CDN url, please update it.

```diff
- <script src="https://unpkg.com/css-prefers-color-scheme/browser"></script>
+ <script src="https://unpkg.com/css-prefers-color-scheme/dist/browser-global.js"></script>
```

```diff
- <script src="https://unpkg.com/css-prefers-color-scheme/browser.min"></script>
+ <script src="https://unpkg.com/css-prefers-color-scheme/dist/browser-global.js"></script>
```

##### Use `prefersColorSchemeInit` to initialize the polyfill in the browser.

```diff
- initPrefersColorScheme()
+ prefersColorSchemeInit()
```

##### Remove `@media (prefer-color-scheme: no-preference)` from your CSS.

`@media (prefers-color-scheme: no-preference)` was removed from the specification and should be equivalent to not having any media query.

```diff
- @media (prefers-color-scheme: no-preference) {
- 	.some-selector {
- 		/* your styles ... */
- 	}
- }
+ .some-selector {
+ 	/* your styles ... */
+ }
```
