Last week brought a total of 1,228 changes, 529 at WebKit and 699 at Chromium. Highlights include CurveCP, a possible alternative to the TCP transport layer, multi-core SVG Filters and DynamicsCompressorNode.
A private extension API has been added to Chromium adding the capability to communicate with handshake-less TCP service via a proxied Web Socket, such as IRC and SSH. This addresses one of the limitations which were made in favor of security and will, for now, only be available for selected extensions like an SSH client.
Furthermore, an initial implementation of Dan Bernstein’s CurveCP transport layer landed in Chromium. While the plans are still unknown and not everyone is optimistic about the layer itself, CurveCP is similar to TCP but uses high-speed high-security elliptic-curve cryptography to protect every packet against espionage and sabotage.
Web Inspector has been enhanced with the ability to collect background networking events. These are events which occur while the Inspector itself is closed, but will be available when you open it up again. Non-color properties won’t receive a color picker in the Styles pane anymore and incrementing or decrementing very large numeric values in CSS rules no longer results in an invalid declaration.
Now that the ParallelJobs Framework has been available for about a month, work has started to enhance several SVG filters to distribute work over multiple processor cores. The FELighting, FEGaussianBlur and FEConvolveMatrix filters have been updated, yielding performance improvements between 10 and 30 percent.
As for specification-related improvements, HTML5’s numeric input won’t show a zero anymore if the input’s range does not allow the value 0. The region of an area element will be updated when it dynamically has been altered, border-radius properties with negative values will be ignored and document.activeElement will now point to the active iframe element in case content within it has been focused.
