A web developer’s guide to the latest Chrome Beta

Other new features in this release

CSS custom filters have landed behind a flag. They enable sweet cinematic effects like page flipping with just CSS and HTML. You can turn them on with chrome://flags.

Chromium now parses the autocomplete attribute according to spec. Use it to specify which type of saved user data the browser should use to prefill input elements. Examples are name and street-address.

A few brand new features landed with a prefix: -webkit-hyphens gives you more control over hyphenation at line breaks, and -webkit-clip-path enables you to clip DOM content to an SVG shape.

Un-prefixed APIs

IndexedDB, a client-side storage API offering fast access to large amounts of structured data

Intl, which adds support for JavaScript internationalization of date format, number format, collation and non-standard segmentation, and more time zones

postMessage, a feature enabling cross-origin communication (including support for fast transferable objects)

requestAnimationFrame for silky smooth JavaScript animations

performance.now() for reliable, high-resolution timing
