Chrome's push notification feature has graduated from the Canary channel and is now part of the latest Beta release. And you know what that means, right? It's just one step away from being incorporated into the stable browser. Chrome Beta 42 (for all platforms) comes with two new APIs that allows websites to send you notifications even if the browser isn't open. Each message comes with "Site Setting" beneath it, though (as you can see below the fold), providing a way to quickly switch off notifications from that particular service or website.
