• Double clicking on a map zooms into the clicked location
• Scroll wheel functions to zoom in / out.
• Zooming retains the previously loaded images until the new ones load.
• UI layout tweaks. The links from the right hand side of the search bar have now been moved to a more “tabbed” look underneath it

On the whole, I like the new features. The navigational controls are more intuitive, although I am going to have to unlearn some of the old behaviours. The scroll wheel functionality appears to me to be back-to-front. Certainly, in Google Earth scrolling the wheel down zooms in, and up zooms out. The implementation in Maps, though, is the opposite.
