Here's the highlight: Though Firefox remains the leader on the SunSpider test, with a score of 2,110, Chrome edged very close with 2,140. A lower score is better; because of some variation in results, the numbers I quoted are an average of several runs.
According to Mark Larson, Google's Chrome program manager, Chrome 0.4.154.33 fixes a crash when opening the Options dialog box on 64-bit Windows and some issues using Hotmail. "Hotmail still does not properly recognize Google Chrome," though, Larson said in his announcement of the new version, though it can be fooled into thinking it's using a more mainstream browser.
