Ruby overhang, HTML5 track element and a full-screen button
Published on in Browser Vendors, Google Chrome, Last Week, tech, WebKit. Version: Chrome 12
The 630 commits at WebKit and 707 commits at Chromium add up to a total of 1,337 commits. And I’m not even kidding. Highlights are two removed events, automated ruby overhang behavior and offline audio rendering for the Web Audio API.
Quite some visual changes have been made to Chromium. The concept of scrolling tabs has been introduced for the Touch UI, ensuring that selected tabs stay in the view. Users of Side Tabs will have noticed two new arrows at the top of the tab-bar, allowing you to scroll through the tabs upwards and downwards. The profile button has been moved a bit, making space for a new full-screen button and a stub implementation has been added for Panels, one thing I really miss for extensions.
Following some discussion and a change to the HTML specification, WebKit has removed support for the onformchange and onforminput events. The CSS parser won’t accept #papayawhip as a valid color anymore, WebKit’s Server-Sent Events implementation will now only accept UTF-8 as its encoding and negative shadow spread should not round inset shadows. Finally, hidden iframes won’t receive focus anymore.
Dan Bernstein had a go at improving WebKit’s ruby implementation by adding support automated overhang, which means that ruby text can overhang characters adjacent to the base text. While this has become the default and only behavior for WebKit, as the ruby-overhang CSS property has not been implemented yet, the specification’s draft does not reflect the new initial value yet.
Now that the Web Audio API has been in development for well over a year, work has begun on making it testable. Offline audio rendering has been added to the AudioContext API and DumpRenderTree (the testing-framework) for WebKit’s Mac port has been improved with supporting audio tests.

And that’s it again. If you hadn’t noticed yet, last Tuesday I announced that I’ll be joining the Google Chrome team in June. While the set-up of these updates may change, I definitely intend to continue making them!
