Google Chrome beta version 17.0.963.26 released comes with two of Chrome's core principles improvements: speed and security -- along with "New Extensions APIs, updated omnibox prerendering, download scanning protection, and other small changes."
On the speed improvement "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," informs Google.
And, on the security releaed improvements Chrome's Safe Browsing technology should now help protect from additional types of malware attacks, as "Chrome now includes expanded functionality to analyze executable files (such as ".exe" and ".msi" files) that you download," revealed Google.
"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," informs Google.
"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," Google said.
Try out these changes in the new Chrome Beta.
Also, released today in the version 16.0.912.75 of Chrome for the Stable channel for Windows, Mac, Linux and Chrome Frame.
