Google has updated the Chrome application to version 42, bringing a couple new features and some performance improvements.
Sites will now be able to set up notifications through Chrome so the app can send you alerts without having to download the main site's app. It could be useful for something like a shopping site or social network where the user didn't want to download the app but still wanted to keep up with it. Not exactly a common use-case scenario, but having the option is nice.
It'll also be easier to create home screen shortcuts to your phone through Chrome thanks to a new banner that will start appearing on sites you frequent.
The update isn't huge, but it's something. Keep an eye out for it over the next few days. If you don't feel like waiting, you can grab the update directly from the link below.

Sounds a good use case for Facebook, the app is not one you would want.
