The latest update to Google Search isn’t a major one, but is most likely preparing for their open sourced Google Now cards update which allows developers to put their own content into Google Now from their apps. Other changes we did notice included tweaks for media playback cards, a new UI layout for “relationship with contacts” which allows you bind contacts with family nicknames, such as labeling someone as your mother or father, and telling Google to “Call Dad”.
Below is the link for download, which will simply update your current app. The over-the-air update will probably roll out in the next few days, so this is a quick way to get the update now.
