React v0.11.2

16 septembre 2014 par Paul O’Shannessy

This blog site has been archived. Go to react.dev/blog to see the recent posts.

Today we’re releasing React v0.11.2 to add a few small features.

We’re adding support for two more DOM elements, <dialog> and <picture>, as well as the associated attributes needed to use these elements: open, media, and sizes. While not all browsers support these natively, some of our cutting edge users want to make use of them, so we’re making them available to everybody.

We’re also doing some work to prepare for v0.12 and improve compatibility between the versions. To do this we are replacing React.createDescriptor with React.createElement. createDescriptor will continue to work with a warning and will be gone in v0.12. Chances are that this won’t affect anybody.

And lastly, on the heels of announcing Flow at @Scale yesterday, we’re adding the ability to strip TypeScript-like type annotations as part of the jsx transform. To use, simply use the --strip-types flag on the command line, or set stripTypes in the options object when calling the API. We’ll be talking about Flow more in the coming months. But for now, it’s helpful to know that it is a flow-sensitive JavaScript type checker we will be open sourcing soon.

The release is available for download from the CDN:

We’ve also published version 0.11.2 of the react and react-tools packages on npm and the react package on bower.

Please try these builds out and file an issue on GitHub if you see anything awry.
