Last week, 751 changes landed in the WebKit repository. Highlights include landing of the Battery Status API and support for the W3C version of the Fullscreen API.
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.
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.
