Google Chrome 29.0.1516.3 Dev is now available for download for all major platforms, thus giving users the option to check out some new features before hitting the stable build.Given the fact that Google has just updated its listing, no release notes are available for the time being, but since we're talking about a developer build, expect the app to be a bit unstable, regardless of whether you are running Windows, Linux or Mac OS X.
Of course, some developer tools are also included to help determine the cause of the errors you may encounter, so it's pretty obvious that you can't use this build as your everyday browser.
Still, if you're looking to download a stable version of Chrome, check out the build available on this page.
