We just got word that the Facebook app for Windows Phone got bumped to v1.5, which you can grab right now in the Marketplace.

Earlier, we reported that this app was supposed to be getting notifications and that it was coming "soon". While an update did in fact come soon, we're not seeing any options under Settings for notifications but perhaps we're missing something (it's only been about 5 minutes since we updated). We did noticed the "Refresh" setting is now "Cache expiration" and set at 10 minutes, but other than that...

Anyways, you can grab the app here. Sound off in comments on anything you notice different or better and we'll update this post with the info.

Thanks, @deeper2k, for the heads up
