Google released an update for Chrome Dev channel. The new revision is 23.0.1262.0 and it is available for all supported platforms (Windows, Mac, Linux, and ChromeFrame).
The new V8 version adds validity checking to API functions and calls and activates fixed ES5 read-only semantics by default.
On Mac, the change consists in the fact that the favicons for chrome:// URLs (i.e. Settings, bookmark manager, history) are better looking because they are high DPI.
On Linux, the new sandbox should be more robust when denying socket calls.
