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.
Chrome Apps and Extensions APIs
signedInDevices API
allows you retrieve a list of the user’s signed-in devices.
MediaGallery API
now supports import of Picasa albums.
The
Identity API
now provides
events
such as sign-in and sign-out.
Websites in incognito tab can now
connect
to Apps with user consent.
chrome.runtime API
now optionally provides TLS channel ID to extensions or apps to allow for stronger security.
