Today we’re sending out React 15.6.2. In 15.6.1, we shipped a few fixes for change events and inputs that had some unintended consequences. Those regressions have been ironed out, and we’ve also included a few more fixes to improve the stability of React across all browsers.

Additionally, 15.6.2 adds support for thecontrolList attribute, and CSS columns are no longer appended with apx suffix.

Installation

We recommend usingYarn ornpm for managing front-end dependencies. If you’re new to package managers, theYarn documentation is a good place to get started.

To install React with Yarn, run:

yarnadd react@^15.6.2 react-dom@^15.6.2

To install React with npm, run:

npminstall--save react@^15.6.2 react-dom@^15.6.2

We recommend using a bundler likewebpack orBrowserify so you can write modular code and bundle it together into small packages to optimize load time.

Remember that by default, React runs extra checks and provides helpful warnings in development mode. When deploying your app, make sure touse the production build.

In case you don’t use a bundler, we also provide pre-built bundles in the npm packages which you caninclude as script tags on your page:

• React
  Dev build with warnings:react/dist/react.js
  Minified build for production:react/dist/react.min.js
  
• React with Add-Ons
  Dev build with warnings:react/dist/react-with-addons.js
  Minified build for production:react/dist/react-with-addons.min.js
  
• React DOM (include React in the page before React DOM)
  Dev build with warnings:react-dom/dist/react-dom.js
  Minified build for production:react-dom/dist/react-dom.min.js
  
• React DOM Server (include React in the page before React DOM Server)
  Dev build with warnings:react-dom/dist/react-dom-server.js
  Minified build for production:react-dom/dist/react-dom-server.min.js
  

We’ve also published version15.6.2 ofreact andreact-dom on npm, and thereact package on bower.
