When Google holds an event, expect big news to go down. Between the announcement of a streaming music service that combines Google's cloud library with your own  downloads to an updated search system that uses conversational speech, the Android crowd had plenty to get excited about during the tech company's Google I/O Wednesday keynote. Here, catch up on what changes are coming to the Google-sphere.
Hangouts, the video chatting feature for Google+ , is now a standalone app for Android and iOS and Chrome extension. By eliminating the barriers that stand between users of various platforms, the app just might change the way we communicate.
The New Google Maps
Google announced an update to Maps , with a beautiful new interface and more personalized search. You set standard locations, like home and work, but it's the personal landmarks that make the map useful. These landmarks are restaurants or other places you frequent. Maps can suggest similar places to you and get better at recommendations over time.
With improvements to Google Search , you'll be able to speak commands not just from your mobile app, but also from Chrome on desktops, using less-robotic speech and receiving spoken responses from Google.
The new Google+ will deliver a modernized stream  and new social discovery experience to its 190 million active "Plus-ers." With changes to the stream, photo editing, and the use of hashtags, will this be the push you need to adopt the social network?
Music Subscription Service
Google Play Music All Access  is the tech company's take on the growing popularity of services like Rdio and Spotify, which give customers instant access to millions of songs based on monthly subscription models.
Gmail Quick Actions
