Google releases initial versions of 64-bit Chrome for Windows
Google has started to publicly test a 64-bit version of <a href="http://macnn.com/rd/311080==http://www.electronista.com/articles/14/05/28/policy.change.forces.chrome.users.to.install.exten sions.only.from.chrome.web.store/" rel='nofollow'>Chrome</a>, the company has announced, in an attempt to improve the speed and security of the browser. Two versions of the 64-bit Chrome for Windows, <a href="http://macnn.com/rd/311081==https://www.google.com/chrome/browser/index.html?extra=devchannel" rel='nofollow'>Dev</a> and <a href="http://macnn.com/rd/311082==https://www.google.com/intl/en/chrome/browser/canary.html" rel='nofollow'>Canary</a>, are available to download by default on Windows 7 and Windows 8, though it will still offer the 32-bit version in both channels as an alternative option. <br />
<br />
"The majority of our users on Windows 7 or higher now have systems capable of running 64-bit applications, and this version of Chrome can take advantage of these newer capabilities," <a href="http://macnn.com/rd/311076==http://blog.chromium.org/2014/06/try-out-new-64-bit-windows-canary-and.html" rel='nofollow'>writes</a> software engineer Will Harris on the <em>Chromium Blog</em>. <br />
<br />
The move to 64-bit will allow the browser to use a "more modern instruction set," recent compiler and processor optimizations, and a new calling convention allowing for function parameters to be passed by registers quickly, in theory giving an average speed boost of 25 percent. By using <a href="http://macnn.com/rd/311077==http://blogs.technet.com/b/srd/archive/2013/12/11/software-defense-mitigating-common-exploitation-techniques.aspx" rel='nofollow'>High Entropy ASLR</a> on Windows 8 and other functions, security is hoped to be improved in Chrome, while earlier testing of the browser reported a "marked increase" in stability compared to the 32-bit version. <br />
<br />
<em>The Next Web</em> <a href="http://macnn.com/rd/311078==http://thenextweb.com/google/2014/06/03/google-launches-64-bit-version-chrome-starting-dev-canary-channels-windows-7-windows-8/" rel='nofollow'>expects</a> that, based on a six-week development cycle used on Chrome, a 64-bit beta release is unlikely to arrive before August, with the stable version of the browser likely to ship some time afterward. <br />
<br />
A 64-bit version of the Chrome browser has been available for Linux for some time now, and though there is not currently a version for OS X, it does appear that <a href="http://macnn.com/rd/311079==https://code.google.com/p/chromium/issues/detail?id=18323" rel='nofollow'>some development</a> has taken place on the project.
