Today we are releasing React 15.6.0. As we prepare for React 16.0, we have been fixing and cleaning up many things. This release continues to pave the way.
In React 15.6.0 the onChange
event for inputs is a little bit more reliable and handles more edge cases, including the following:
range
with the arrow keys (issue 554)Thanks to Jason Quense and everyone who helped out on those issues and PRs.
We are also including a couple of new warnings for upcoming deprecations. These should not affect most users, and for more details see the changelog below.
After the last release, we got valuable community feedback that deprecation warnings were causing noise and failing tests. In React 15.6, we have downgraded deprecation warnings to use console.warn
instead of console.error
. Our other warnings will still use console.error
because they surface urgent issues which could lead to bugs. Unlike our other warnings, deprecation warnings can be fixed over time and won’t cause problems in your app if shipped. We believe that downgrading the urgency of deprecation warnings will make your next update easier. Thanks to everyone who was involved in the discussion of this change.
We recommend using Yarn or npm for managing front-end dependencies. If you’re new to package managers, the Yarn documentation is a good place to get started.
To install React with Yarn, run:
yarn add react@^15.6.0 react-dom@^15.6.0
To install React with npm, run:
npm install --save react@^15.6.0 react-dom@^15.6.0
We recommend using a bundler like webpack or Browserify 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 to use the production build.
In case you don’t use a bundler, we also provide pre-built bundles in the npm packages which you can include as script tags on your page:
We’ve also published version 15.6.0
of react
and react-dom
on npm, and the react
package on bower.
