Support for the overflow-wrap property has been added, which is a new property to which word-wrap is a shorthand. Within the calc() function, expressions using the “em” unit will now zoom correctly and it’s now possible to use CSS Variables within expressions, assuming support for both is available in your build. Robert fixed yet another CSS 2.1 issue, so WebKit now prevents the margins of collapsed blocks from collapsing with parent margins.
Dirk introduced the “clip-path” CSS property into WebKit, which restricts the region of an element that can be painted. Changes landed making this work for both HTML and SVG elements, together with a fix which makes sure that the correct origin of polygons will be applied.
Last week saw 993 Chromium commits and 650 WebKit ones, totaling up to 1,643 changes in total.
Chrome binaries will now be signed with compatibility GUIDs for Windows 8, which mainly impacts theming in High Contrast mode and heuristics about potential compatibility issues. Furthermore, forwarding of search queries in Windows 8 UI mode has been implemented, and mouse input events from styli will no longer be ignored.
Web Inspector’s Profile panel is getting a great new (experimental!) feature from Andrey, namely WebGL inspection. The Timeline panel is now able to show the cause for a style recalculation, the console.time() method now uses performance.now() for more accuracy and more work has been doneon improvingperformance.

The postMessage() function now accepts any kind of data as its message, allowing you to post arrays and objects as well. Changing the class attribute on any kind of element will now update the classList as well, and work is being done for allowing pointer lock in sandboxed iframes. The automatic DOM transactions feature for Undo Manager is now implemented, just like the item() method, and the undoscope attribute has been removed.
Last week, 764 Chromium commits and 615 WebKit commits landed, totaling up to 1,379 changes.
Especially for Web Applications, finding certain files in the Network tab can be difficult, as there can be hundreds. Web Inspector now gained support for filtering the display based on search results! The BlackBerry 10 user-agent can now be selected in the Settings dialog, and workisbeingdone to improve performance by loading panels lazily.
SVG Filters can now be drawn in the correct colorspace for WebKit ports which don’t use CoreGraphics.

Finally, many more languages now have their localized quotes available for the <q> element.

Web Inspector’s editor can now be replaced with CodeMirror by Jan Keromnes, as an experimental feature. It supports basic editing, search, replace and saving, but much more work is to be done before it’s completely usable. The function scope is now visible in the UI, and support for two CSS Region events has been added to the protocol.
A total of 1,599 commits landed last week, 745 for WebKit and 854 for Chromium.
Extensions using script badges will soon be able to use the Command API, allowing them to declare keyboard shortcuts for triggering events on an extension. Browser integration will become a lot richer with this addition!

The webkit prefix has been dropped from the Vibration API implementation as it reached Candidate Recommendation. Overflow will no longer apply to table rows and row-groups, instead, it only applies to block containers, and a bunchofimprovementshave been made to the Flexible Box implementation as well.

Work isbeing done on re-implementing support for quotes and the <q> element.
Web Inspector’s User Agent setting screen has been renamed to Overrides.
As for new features, a build flag was added announcing work on CSS Blending and Compositing.

A compile time flag has landed, marking the beginnings of an implementation of the HTML5 <dialog> element. Meanwhile, support for the old hixie-76 Web Socket protocol has been removed.
With just 770 commits last week, 333 at Chromium and 437 at WebKit, the impact of the Independence Day celebrations is quite visible. Since the open-sourcing of Chromium in 2008, there have been only 11 weeks during which WebKit received more commits than Chromium.
The context menu for nodes in Web Inspector now includes a “Scroll into view” item. Snippets can be evaluated and the visual appearance of Web Socket frames has been improved.
