Google has a new Beta version of Earth available for download or updating, depending if you have a previous version of Earth on your system or not. According to Google, their new Earth software includes the following:

New! in Earth 4.3 (beta)

Photo-realistic Buildings

With Google Earth 4.3, see 3D buildings faster and in more cities than ever before. Now you can access hundreds of new buildings from the world’s cities, including San Francisco, Boston, Orlando, Munich, Zurich, and dozens more.

Swoop Navigation

Fly seamlessly through the landscape with new navigation controls. Swoop from outer space to street level and leap from one building top to another. Use the look joystick to view buildings as if you were standing right in front of them.

Light and Shadow

With the new Sunlight feature, you can watch the sunrise and sunset from anywhere. Move the time slider to watch dusk, dawn and shadows move across the Earth.

Street View

Street View, available in Google Maps, is now in Google Earth! Fly into panoramic images of select cities and take a 360 degree tour.
