Google is updating its dev-channel version of the Chrome browser this week with an updated JavaScript engine and a long list of bug fixes.
Chrome 10.0.642.2 is an update for Windows, Linux and Mac and includes the new V8 version 3.0.7.0 JavaScript engine.
The new version of V8 includes performance improvements on the IA32 (x86) platform as well as enhancing the debugger.
It’s not clear to me how much of a performance delta there is between V8 3.x and its predecessors, but I don’t doubt that once Chrome 10 hits beta that Google will be sure to trumpet its speed.
