Google has promoted the 64-bit version of Chrome for Windows to the browser's more stable Beta distribution channel, and boosted Chrome for OS X to 64-bit on the more preliminary Canary and Dev builds. Chrome for Windows 64-bit shifted to Beta on July 30 after about two months on the less-polished Canary and Dev lines. Google has touted the 64-bit version as more stable and faster than its 32-bit predecessor, which has been the Chrome standard since its 2008 debut.
