Android: Google's rolling out an update to Google Maps on Android that integrates your Google Calendar events and Google contacts into Google Maps. Provided you're signed into Google Maps and Calendar, your calendar events should populate Maps automatically. You'll see a new tab under Your Places marked as "Upcoming", which includes all your upcoming events. Those upcoming events also include bookings and reservations pulled from Gmail.
Google Maps also gets a new labelling system where you can label frequently visited places with a name, like "daycare" so it's easier to navigate there without typing in a bunch of stuff. Finally, your Google contacts are integrated on the map now too, and provided you have an address listed for someone in your contacts you can simply type their name to pull up their address. Android users should start seeing these features today.
