177 authors landed 763 changes in WebKit’s repository last week. This update discusses them, up to revision 134188.

Web Inspector’s console messages now accept multiple formatting blocks by using %c multiple times. The new console.clear() method will, surprisingly, clear the console. An option has been added for disabling rulers, pressing Ctrl+A in the Network Panel now selects the resources rather than the entire panel and warning messages have been added for invalid cross-frame options and usage of the dpi and dpcm units outside of printed media stylesheets.

Canvas images reprojected using the -webkit-canvas() CSS function will now use the full backing store rather than the scaled ones, which improves quality on many mobile devices. Support for the “desktop-width” directive in the meta viewport element has been removed. Also newly supported are date pickers for <input type=month> and <input type=week>, and Skia is now able to use reference URL filters on composited layers.

It’s now possible to show a list of tracks available for media elements, an UI for which will be implemented soon. A touchEvent’s client{X,Y} attributes will have the right scrolling adjustments applied, proper escaping of quotes will now be applied in various HTML extension methods (String.prototype.anchor, link, etc) for JavaScriptCore and getUserMedia() will now throw a TypeError instead of a DOMException.

The Content Security Policy DOM implementation has been updated to match the specification. The interface is now called document.securityPolicy and various methods are now exposed as read-only properties.
