Google announced version 3 of the google maps API.

Some things I noticed right away:

• no API key required! before you had to sign up for an API key, but now you can shed your API key woes (I know I had them) and not have to sign up for one again.
• mobile browser support (iphone and android)
  
• You now have to specifiy the sensor variable in your include of google maps
  <script type="text/javascript"src="http://maps.google.com/maps/api/js? *sensor=true* ">
  the sensor is for detecting user’s location with mobile sensors like GPS
• No more polluting the global namespace with tons of variables. Google is moving over to their google namespace. so instead of new GMap2 you do new google.maps.map
• New mouse event object.
• Default UI so that as Google maps updates their UI, you get to enjoy the new interface without updating code.
• it is like 3AM now so that is enough changes to see before I go to bed. =P

The only thing I couldn’t figure out is where is the directions object? A lot of my maps applications use driving directions, so I’ll be holding off on migrating over until I figure that out with the new API.
