On average, web-pages now load approximately 5% faster than earlier Chrome releases thanks to optimizations made by Google's developers. Chrome is already known for being rather fast, but now it's becoming even faster.
Besides being faster, Chrome 27 for Linux, Mac OS X, and Windows also introduces the new chrome.syncFileSystem API, and various other improvements. There's also been a number of bug/security fixes as part of this new release.
More details on the new Google Chrome web-browser release can be found via the project's blog.
