Chrome 32 Beta: Animated WebP images and faster Chrome for Android touch input

Thursday, November 21, 2013

The latest Chrome Beta channel release includes a slew of new developer features that make the web faster and safer for users. Unless otherwise noted, changes apply to desktop versions of Chrome and Chrome for Android.

Animated WebP

The animated WebP image format offers some important improvements as an alternative to animated GIF, including true alpha channel (8-bit) as compared to a binary (1-bit) alpha in GIFs. Also, each frame can be lossy or lossless as needed. Compare the animated WebP version (372 KB) of the picture below to the animated GIF version (870 KB). The WebP version is 57% smaller.



300ms tap delay removal on Chrome for Android

Starting this release, responsive mobile websites will get a performance boost in Chrome for Android because we’ve disabled double-tap zoom. Previously, to support double-tap zoom, Chrome had to delay every touch event sent to the webpage by 300ms to allow the user to tap a second time. Now mobile-friendly sites that are already formatted to automatically fit in the page width will receive click events instantly and can respond to user input more quickly.

NPAPI plug-ins blocked by default

As we announced a few months ago, all but a handful of Netscape Plugin Application Programming Interface (NPAPI) plug-ins will be blocked by default starting in today’s Beta. Check out the developer guide to learn more.

Vibration API

New in Chrome for Android, the Vibration API allows web developers to programmatically provide tactile feedback in the form of vibration. Use cases include improved accessibility and more engaging browser-based games.
