  204. ## 4.0.0
  207. This builds upon [the second release candidate](https://github.com/select2/select2/tree/4.0.0-rc.2), **so review all previous release notes** before upgrading from previous versions of Select2.
  209. ### Supported environments
  210. - jQuery 1.7.2+
  211. - Modern browsers (Chrome, Firefox, Safari)
  212. - Internet Explorer 8+
  214. ### New features
  215. - Fully compatible with AMD and UMD based loaders.
  216. - Advanced plugin system that [uses custom adapters](https://select2.org/advanced/adapters-and-decorators).
  217. - Full support for `jQuery.noConflict`.
  218. - A `<select>` is the recommended element and [can be used for all options](https://select2.org/upgrading/migrating-from-35#no-more-hidden-input-tags). There is limited backwards-compatible support for the `<input>` element in [full builds](https://select2.org/getting-started/builds-and-modules).
  219. - [Declarative configuration through `data-*` attributes](https://select2.org/configuration/data-attributes)
  220. - Easy to configure theme system and new default theme
  221. - You can use more specific locales (like `en-US`) and Select2 will be able to determine what translation files to load.
  223. ### Breaking changes
  224. - Select2 now uses the MIT license
  225. - [The full build](https://select2.org/getting-started/builds-and-modules) of Select2 no longer includes jQuery - You must include jQuery separately on your page.
  226. - Select2 will prevent the inner scrolling of modals (and other scrollable containers) when it is open to prevent the UI from breaking. [Read more at the commit.](https://github.com/select2/select2/commit/003d6053a9fff587c688008397e7d5824463fe99)
  227. - jQuery is no longer listed as a dependency in the `bower.json`/`component.json` files.
  228. - [`<select>` has replaced `<input type="hidden" />`](https://select2.org/upgrading/migrating-from-35#no-more-hidden-input-tags) for **all options** (_including remote data_)
  229. - The [`matcher` has been revamped](https://select2.org/upgrading/migrating-from-35#advanced-matching-of-searches) to include full context, a compatibility module (`select2/compat/matcher`) has been created
  230. - The [display always reflects the order](https://select2.org/upgrading/migrating-from-35#display-reflects-the-actual-order-of-the-values) data is sent to the server
  231. - The click mask is no longer the default (again). You can get back the old functionality by wrapping your `selectionAdapter` with the `ClickMask` (`select2/selection/clickMask`) decorator.
  232. - Select2 no longer stops the propagation of events happening within the dropdown and selection. You can use the `StopPropagation` modules available in the [full builds](https://select2.org/getting-started/builds-and-modules) to prevent this. [https://github.com/select2/select2/commit/8f8140e3b00c5d5bb232455137c4c633d7da4275]
  233. - The enter key no longer toggles the state of multiple select items in the results, but instead will only select them. Use CTRL + Space instead to toggle the state. [https://github.com/select2/select2/commit/017c20109471fa5b835603faf5dc37f7c2c2ea45]
  234. - Warnings will now be triggered in the developer console if Select2 detects an unsupported configuration.
