This update discusses the 1,305 WebKit changes up to revision 128,016, and the 1,707 Chromium changes up to revision 155668, and is therefore covering the last two weeks.
Within Web Inspector, the $() function now aliases querySelector rather than getElementById, meaning you can also select on classes, elements or more advanced selectors. Stylesheets using SASS’ SCSS format will now be highlighted. The experimental WebGL front-end is now able to link you the relevant call in the source code and status bar glyphs now have high-DPI images.
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.
Using Content Security Policy will now disable dynamic script evaluation in workers. Automatic features (i.e. autoplay) will now work in sandboxed iframes if they allow scripts and TextTrack modes will now be reported as strings. MediaSource objects now have a duration property, non-anchored <dialog> elements will now be vertically centered and dynamically removing preserve-3d from a layer now yields the wanted effect. Finally, the MediaSource, SourceBuffer and SourceBufferList objects have received WebKit-specific prefixes.
Tommy has been working on WebRTC’s PeerConnection interface, adding the asynchronous createOffer method, the createAnswer method, ICE-related functionality and support for local and remote descriptions.
In terms of experimental features, Dave’s been working on the new Multiple Column implementation again, and added support for painting the contents, column repainting and unforced column breaking, next to some clean-ups. The CSS Shaders implementation now features various new blending and compositing modes.

And that’s it again, thanks for reading! For Chromium OS updates, François published some great updates again.

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 done on improving performance.
Simon landed support for sticky CSS positioning, which limits an element to be positioned within both it’s container and the viewport. Support for parsing the -webkit-text-decoration-style has been added, the arguments for the blend-mode property can now be parsed and CSS masking and filters are now being applied in the right order.
Blob and File System URIs are now considered to be same-origin for Content Security Policy and computed styles for 2D Transforms have been aligned with the specification. An initial implementation of CSS Exclusions’ shape-inside property landed, WebKit didn’t miss out on the usual set of Flexbox improvements and David’s work on re-implementing Multiple Columns on top of CSS Regions saw two more commits.
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.
Another new feature which is in the works, is being able to use the “overflow-y” property as a way to make the render view paginated, as part of implementing the Generated Content for Paged Media specification.

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 work is being done to improve performance by loading panels lazily.
Parsing support for CSS’ blend-mode property, defined in the CSS Compositing and Blending specification, has landed. The volume sliders for fullscreen and normal media elements will now stay in sync, the first call to webkitRequestAnimationFrame won’t return 0 anymore and z-indexes now work on flexible items without explicitly positioning them.
SVG Filters can now be drawn in the correct colorspace for WebKit ports which don’t use CoreGraphics. Mike implemented the plugin-types and form-action Content Security Policy directives, together with their respective DOM APIs, and support for author Shadow DOM is now available for the <meter> element. Finally, many more languages now have their localized quotes available for the <q> element.
Other changes which occurred last week:
- The third-party storage blocking system now also covers WebSQL databases.
- A compile time flag was added for the new CSS 3 text decoration properties.
- Chromium received a new audio render method supporting synchronized input and output.
- Sticky CSS positioning has been enabled on Apple’s Windows port.
- DNS Prefetching has been enabled for the BlackBerry WebKit port.
- Gyuyoung Kim is the latest member of the WebKit Reviewer team, congratulations!

Various new features are still under development in WebKit, and may be near the horizon: @supports and parts of Generated Content for Paged Media (GCPM).

Jim Carrey is going to be very pleased with this change made by Anthony last week, namely kicking Chromium to Number 23. You can read about many changes made for Chrome 22 in this series of articles.
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 new “all” value for the -webkit-user-select property can now be parsed and initial support for text-decoration-line landed. Four more bugs in the Flexible Box Module implementation were fixed, namely the lack of support for inline flexing, percentage sizing in quirks mode, percent-based margins and behavior when using box-sizing.
ArrayBufferView objects can now be send through Web Sockets, the indexed getter for Microdata will now return undefined instead of empty strings, classList can now remove classes with uppercase characters and window.URL has been unprefixed. The <progress> element now supports author Shadow DOM. Content Security Policy now is nosier about errors and more work was done on CSS Region’s CSSOM implementation.
In terms of new features, a compile-time flag for CSS Hierarchies has been added, and work is being done on implementing Proximity Events in WebKit.
