The Google Search app has been updated bringing the usual bug fixed and improvements, but it also adds hotword support for British and Canadian English. The Google Experience Launcher also gets updated with a new name. It's now called the Google Now Launcher, which could mean that a Play Store launch is imminent. Some of the updates for the launcher include new Google Now Launcher name on the splash screen start up, 6 columns on tablet home screens, AirBNB reservations in Google Now, and icon imports from old home screens.
If you have the Nexus 5, the launcher will get updated automatically and you won't see the new branding, but if you are using the old Google Experience Launcher on another device, we have the update below. Of course you can install it even if you haven't tried it before. Either way, you will need the Android 4.1+ and the original Google Home Launcher app installed in order to see the Google Now Launcher. We have download links after the break.

Is there a reason why Google is holding out on their launcher (why only the nexus device has it)?
