Chrome Beta Release Now Prefetching Faster [chrome.blogspot.com]
To get you where you want to go even faster, Chrome will now start loading some web pages in the background, even before you’ve finished typing the URL in the omnibox. If the URL auto-completes to a site you’re very likely to visit, Chrome will begin to prerender the page. Prerendering reduces the time between when you hit Enter and when you see your fully-loaded web page--in some cases, the web page appears instantly.
Security features updated
To help protect you against malicious downloads, Chrome now includes expanded functionality to analyze executable files (such as “.exe” and “.msi” files) that you download. If a file you download is known to be bad, or is hosted on a website that hosts a relatively high percentage of malicious downloads, Chrome will warn you that the file appears to be malicious and that you should discard it. We’re starting small with this initial Beta release, but we’ll be ramping up coverage for more and more malicious files in the coming months. Remember, no technical mechanism can ever protect you completely from malicious downloads. You should always be careful about which files you download and consider the reputation of their source.
