Exactly 1,234 patches landed in the Chromium repository last week, and 751 in WebKit’s, totaling up to 1,985 changes. Highlights include many form-related changes, the Battery Status API and performance improvements.

All signed and float Typed Arrays will now show up as normal arrays in Web Inspector. Taking heap snapshots should now be 12% faster and work is being done in preparation of supporting snippets in the Script Panel. A meta bug covering that work is available on WebKit’s Bugzilla.

CSS parsing now follows the specification when it unexpectedly runs into the end of a file and widths set on a column group won’t affect a column’s width anymore for fixed-layout tables. Three issues with the Flexible Box Layout implementation have been fixed, the “em” unit will be used correctly even when a :first-line pseudo-element changes the size and calc() can now mix percentages and absolute values for gradients and fonts.

The HTML5 meter and progress elements aren’t form--associated anymore, out-of-document radio buttons are now grouped when associated with a form and the form-attribute for labels had its behavior updated. The outer element is now labelable, while hidden input fields have lost that capability. Despite being reverted, support for color inputs seems to be really close for Chromium now.

Samsung has landed an implementation for the Battery Status API, to be enabled on the EFL port. As for Speech Recognition, stubs for WebCore’s controller and the client landed, as well as the SpeechRecognitionEvent part of the API. The MediaStream’s PeerConnection implementation has been deprecated as it’s moving towards a JSEP API. Meanwhile, Nikolas Zimmermann has been busy implementing proper animVal support for SVG.

Besides support for Mozilla’s FullScreen API, WebKit now also supports the very similar W3C Fullscreen API. The primary differences lie in capital usage for the methods and behavior while exiting fullscreen.

Other changes which occurred last week:
